(I will be posting each game turn in this thread as it plays out, probably one-two turns per week.)

Season: Summer

Optional Rules:
15.1 Air Cushion Vehicles
15.5.1 OPLAN 5029 Leaked
15.5.2 OPLAN 3600 Leaked
15.10 Busan Nuked
15.11 Refugees

Rules from Game Series Supplemental #1
Cyber Warfare Rules
Alternate Advanced Game Air System
Optional Rule 1.0 Naval Air Defense Umbrella
Optional Rule 2.0 Stacking for US BCTs
Optional Rule 4.0 Ports as Hardened Targets
Optional Rule 5.0 Low Odds Attacks

Situation:
With tensions peaking, the US sees a widow of opportunity for action closing as the North barrels forward with a program to field multiple nuclear-capable ICBMs. Similarly, North Korean fears of an imminent US invasion cause Pyongyang to see its own window of opportunity closing: either attack now and have a chance of victory, or wait while the US conducts a buildup of forces that the North will have no chance of stopping. While the US, Japan, and ROK conduct some of the largest combined exercises ever, the North fields one long range missile using minimal denial and deception techniques and a second missile using more advanced denial and deception. While the allies are consumed with watching the every movement of these two systems, the North implements a plan to deliver a nuclear payload via shipping container to Pusan. After the explosion, the North denies all culpability and variously blames Islamic terrorism directed at the US forces based there and on an alleged secret ROK weapons program. World opinion is in turmoil with some countries, such as Russia, Iran, Venezuela et. al., supporting the North's version of events. Even the US is uncertain what exactly happened for weeks afterwards. Claiming the US and ROKs would use this as a pretext for invasion, the North invokes its sovereign right of self-defense and invades the South. The ROKs will not accept a second nuclear detonation on their peninsula, and so the allies plan a conventional war to unite the peninsula. Japan’s offer of assistance is accepted excluding the deployment of ground forces.


Concept of Operations, North Korea:

Main Attack
2nd Corps, 5th Corps, the 820th, the 815th and the 806th have the main attack. After penetrating DMZ, conserve combat power until supporting attack in the east succeeds and can begin flanking the ROK forces concentrated opposite 2nd and 5th Corps. As the main attack succeeds in isolating ROK forces within Seoul, the 806th will break away and take population centers deep within the ROK.

Supporting Attack
1st Corps and the 108th have the supporting attack. They will penetrate the DMZ and proceed south beyond the mountains, then turn west and flank the ROK forces opposite the main attack. 108th, if possible, will break away and capture population centers. Supporting attack will get priority for SOF support.

Holding Action
1st 2nd and 4th Corps conduct holding actions to pin opposing ROK forces in place. 1st and 4th Corps advance through the DMZ only after the main and supporting attacks push through the ROK defenses in the central and eastern areas.

Held in Reserve
The 425th, 11th Corps, 10th Corps, the PDC and all Red Guard units will remain in reserve, to blunt any ROK or US counter-attacks.

SOF
SOF’s first priority will be to attack HQs and Supply depots to facilitate the success of the Supporting Attack. Second priority will be to attack, and target for SCUDs, airfields, ports of debarkation, and supply depots.

Deep Fires (SCUDs and Air)
SCUDs and Air will reduce enemy sortie generation by attacking airfields, and hinder enemy reinforcement by attacking ports of debarkation. If either the main or supporting attack seem at risk of bogging down, Air will switch to CAS as much as possible.

Cyber
First priority is to suppress enemy air operations, second to support friendly air operations, third to support the ground fight.




Concept of Operations, South Korea:

Defense of DMZ
TROKA east of Seoul and FROKA will hold dug-in positions in the DMZ as long as possible without being destroyed. They will inflict maximum damage on North Korean forces from advantageous defensive positions. SROKA will be in reserve, positioning itself to support gaps in the TROKA AO east of Seoul but west the major mountain range near the coast.

Defense of Seoul
TROKA near Seoul, and the CDC, will deter or defeat a direct North Korean attack on the capital.

Trading Ground for Time
After North Korean forces have penetrated the DMZ, ROK forces will fall back as much as necessary to maintain a cohesive line along terrain advantageous to the defense. ROK forces will seek to create a ring around Seoul.


Counter-Attack
US forces will make an amphibious landing near Wonsan. US forces will seize and hold Wonsan airfield to enable the air insertion of additional forces from both ROK and US. This force will then travel west to capture Pyongyang and destroy defending North Korean forces. As North Korean forces are pulled away from the attack in the South, ROK forces will push north, trapping the North Koreans between the advancing units from the South and the US units moving west.

Held in Reserve
Homeland Reserve and Mobilization Reserve units will form task forces to retake towns and cities overrun by North Koreans. If necessary, these task forces will move to assist defending Seoul.

SOF
SOF’s first priority will be to maximize losses on invading North Korean units by attacking HQs and supply depots. Second priority will be to facilitate deep fires.

Deep Fires (Cruise Missiles and Air)
Cruise Missiles and Air will destroy North Korean air defense system and attack SCUDs. After air supremacy is established, priority will shift to assisting the ground fight either in the defense, or on the counter-attack.

Cyber
First priority is to facilitate deep fires objectives against the air defense system and SCUDs. Second priority is to defend key infrastructure from North Korean attack.

Only days after the port at Pusan was obliterated by a nuclear explosion, while the Allies still were still scrambling to determine what exactly happened, the North's shrill accusations that the South and US were bringing nuclear weapons to the peninsula in preparations for a pre-emptive strike finally changed to strident assertions of their own right to self-defense.

Then the DMZ exploded.

North Korean forces began shelling across the lines while their combat engineers worked to clear lanes through the DMZ. ROK intel detects two concentrations of NK forces: a smaller force just north of Seoul with 2nd and 4th Corps, and a larger force east of Seoul with 5th Corps supported by multiple mechanized units and an artillery brigade. First indications are the main attack will come down the middle with a supporting attack coming north of Seoul.

Additional North Korean mechanized and artillery forces are moving south from their garrisons far in the North. The final destination of these units is unknown, and the ROKs suspect at least some of the mech forces will serve as a strategic reserve.

The North launches salvo after salvo of SCUDs during the first couple days targeting airbases across the South, grounding the entire ROK air force due to damage to airfields and runways and inflicting some permanent losses to ROK aircraft. (The North only hit five out of ten targeted airbases. None were destroyed. The collateral damage caused the ROKs to permanently lose two air package markers, and the aggregate of the strike markers caused the ROK to forfeit five air package markers from its "ready to fly" batch; the ROK only had four "ready to fly" so the SCUDs knocked them out of the fight for now. Fortunately, the Carl Vincent out there in the Sea of Japan still has air assets to throw into the fight immediately.)

The ROKs prepare to defend as long as they can while the ROK/US air force gets fully spun up, and while a substantial invasion force makes it way into Wonsan.

(Hmmm, graphics aren't looking too clear. Can't remember how I've done it in the past. Ahha! Got it.)

Yeah if I don't write it out this way, I'll get lost in the sauce trying to move all these units, and it will just turn into a bar brawl. Definitely helps me out having a large framework within which to work.

As the North Korean offensive takes shape, ROK intelligence revise their assessment of the North's initial strategy: they had been correct in that the main attack is coming right down the middle of the DMZ, but the supporting attack is in the east. North Korea's 2nd and 4th Corps are for the most part holding their ground, pinning the opposing ROK forces in place.

North Korean forces achieve spectacular success, suffering very few losses, in the initial push across the DMZ. The North has already employed chemical weapons three times in order to maintain the momentum of the offensive.

ROK forces so far are managing to keep a cohesive defensive line before the NK Main Attack. ROK defending forces in the east also are still maintaining a fairly cohesive line, but their right flank is open and they are in danger of having the North's 108th Corps swing around to their rear.

The US Marines have already put to sea for their attack at Wonsan. Their plan is to seize the port and airbase, allowing for follow-on forces, then push west toward Pyonyang. The ROK forces in the south just need to hold out long enough to allow for the counter-offensive to bite.

The ROK airforce suffered badly due to the SCUD attacks in the initial outbreak of hostilities, and still has not really entered the fight.

Main Attack
North Korea's 5th Corps continues its push, achieving a breakthrough by pushing back the US 1st Mechanized Brigade of the 2nd Infantry Division. ROK and US forces are already organizing a retrograde of the entire defensive line to attempt to deny NK the opportunity to exploit that breakthrough. Maintaining a cohesive defensive line is critical.

Supporting Attack
North Korea's 1st Corps is getting bogged down fighting the ROK's 8th Corps in the mountains. The ROKs, however, were forced to abandon defense of the flat ground to the east, leaving the way more or less open for the North's 108th Mech Corps to proceed south. ROK forces will continue to attempt to delay the advance of the 108th, though it now seems impossible for the ROKs to maintain any kind of defensive line here.

Air Picture
ROK and US air assets are still struggling to put up as many sorties as they optimally would be capable of, due to the SCUD strikes that preceeded the North's initial ground attack. Nevertheless, what air assets do make it up are keeping the North from controlling the skies, and ground elements are working feverishly to repair as many air air bases and air fields as possible.

ROK/US Counter Attack
The US Marines continue waiting for the Navy to clear the approach to Wonsan, so that they can make their landing. Meanwhile, the 82nd Airborne has arrived in the South. Discussions are underway, considering the possibility of airdropping the 82nd into Wonsan first, if the US/ROKs can establish Air Superiority. If the 82nd can seize the port at Wonsan, the Marines will land there. The Counter Attack needs to happen soon, or else the defensive situation in the South will deteriorate to the point the Marines and the 82nd will have to bolster the forces in the South, and any counter-attack will have to wait. And no one wants to remain on the defensive against the North Korean juggernaut any longer than necessary.







Up in the mountains, the North Korean light infantry were having a field day infiltrating the ROK lines and getting behind the divisions of the ROK's 8th Corps:




More Detailed Notes on the Turn

Electronic Detection Phase
o US failed to effect the electronic detection, but destroyed on of NK’s best cyber chits
o ROKs detect 1st Corps HQ and Kangdong MRL BDE HQ in the east. Failed to detect 5th Corps HQ.
o NK detects 6th Corps HQ in Main Attack, and 8th Corps HQ in Supporting Attack



1st SOF Phase (ROKs)
o ROK SOF finds the 5th Corps HQ, two US and one Commonwealth SOF team that attack. The Commonwealth team is wiped out, but the second US team causes some mischief (strike 1)
o Another ROK SOF team dies trying to find a supply depot serving the Supporting Attack


Air/Naval Phase
o NK gets three Type B and two Type A package markers. ROK gets only two Type B. Commonwealth cyberwarfare operations attempt, but fail, to significantly disrupt NK sortie generation. (NK only has one cyber chit left. It survived this encounter, but once it’s gone, the Allies will have a field day.)
o Already the air picture is improving for the Allies, with the air space Contested


Time for 2nd SOF Phase
o NK puts four SOF raids against the ROK 7th Corps HQ, opposing the Supporting Attack. Two SOF teams are eliminated, and the HQ suffers a Strike 1. Three SOF raids go after the 6th Corps HQ opposing the Main Attack. The HQ suffers a step loss, all SOF teams survive.


1st Strike Phase
o Commonwealth attack destroys the North’s last cyber chit, but fails to impact the strike phase directly. The North’s systems are now more or less defenseless.
o Three NK package markers attack the reduced ROK 22nd Division of 7th Corps in the mountains opposing the Supporting Attack, but two PMs are forced to abort while the third did no real damage.
o Allies put two PMs on SCUD busting missions, to no avail. No losses to aircraft.
o A couple ROK units and a couple NK units get a Strike 1 marker from HQ strikes, and the North lands some SSM on Gangneung, home to some of the helos of 2ID. Damage to the airfield is Strike 1, but no collateral. This is not a good home for the helos, too vulnerable.


1st Supply Phase
o No real issues for either side, though the Allies needed to spend 1 Supply Point to get ammo, water, fuel, etc to the 8th Division of 5th Corps. The HQ was not quite close enough. Refugees are still crowding the roads, but the Allies are managing.


Initiative Movement and Combat
o ROK amphib move the Marine HQ out to sea, ready to assault the shores with the maneuver elements.
o ROK conducts no combat, conserving resources for the defense.
o Light Infantry infiltrate behind the ROK lines in the mountains. Not only do these two Light Infantry Brigades threaten the ROK line, but they also threaten the nearby HQs.
o 1st Marine Division of the Second ROK Army attempts to air assault into the mountains just south of the 23rd Division to bolster the defensive line, protect the HQ of the ROK 8th Corps, and to be in position to slow the advance of the 108th Mech when it attempts to move south along the main coastal highway. Unfortunately, the Marines got shot to crap, lost a step, lost an air mobile point, and were not able to land.
o A brigade of airborne NK SOF paradrops deep into the ROK, southeast of Jeomchon airbase. A second brigade is forced to abandon it mission by air defenses.
o Main Attack - The ROK 5th Corps’ 8th Division bears the full brunt of the North Korean offensive: 2x Light Infantry BDEs from NK 5th Corps; 1x Sniper BDE; 3x Infantry Divisions from NK 5th Corps; and NK 5th Corps’ Armor BDE; supported by 2x Artillery BDEs from the 620th. Odds are column 10, DRM -2. Die roll is a 2. Oh. No. The ROK’s 8th Division is destroyed.
o Supporting Attack – The ROK 22nd DIV and 102nd BDE feel the fury of the supporting attack: 3x Light Infantry BDEs (1x from 1st Corps, the other two national assets); 1x Sniper BDE; 3x DIVs from 1st Corps. Column 10, DRM -2. Die roll is a 3. “HOLD THE LINE!!!” The defending ROK units suffer one step loss, but pass their efficiency check and are able to hold onto their positions!


2nd Strike Phase
o US cyber attacks degrade NK air defenses (-2 DRM)
o Two NK Package Markers fly ground attack missions against Osan AB, destroying it! Luckily no collateral damage inflicted.
o Corps-level assets increase the damage to the NK 1st Corps HQ to a Strike 2 (1st Corps is spearheading the breakthrough the DMZ in the Supporting Attack)


2nd Supply Phase
o In the Supporting Attack, the North Korean penetration of the ROK line and subsequent encirclement of some of the ROK divisions is wrecking both ROK and North Korean supply lines. In the end, one ROK division and an infantry brigade are left out of supply in the mountains, both units at half strength, and will bear the brunt of another NK attack soon.


Reaction Movement and Combat
o Main Attack – The 815th and a Light Infantry BDE over-run a Combat Outpost. 1st BDE of 2ID gets hammered and pushed back by three NK infantry divisions, a Sniper BDE, and three artillery brigades. This will force the ROK defensive line back farther.
o Supporting Attack – Three NK divisions supported by three Light Infantry Brigades and a lot of MRLs bear down on the reduced, out of supply ROK infantry hunkering down in the mountains, with one step loss to each side, which eliminated one of the ROK units (the infantry brigade). The ROKs still hold their position!
o A brigade of NK SOF attempts to paradrop onto the flat ground NE of Gunsan Airbase, then move to secure the installation. They are turned back by AAA.

GT 3, Just Prior to Basic Movement and Combat Phase
Here is the situation in GT 3, a contested turn, just before the Basic Movement and Combat phase.

Main Attack
The North Korean push will likely lose some momentum due to the air and missile strikes against both the 5th Corps HQ and one of its divisions at the vanguard of the attack. North Korea's next move is to have 5th Corps sweep southwest, attacking the ROK's imposing 26th Mech Division while 12th Corps sweeps southeast to attack the ROK's 11th Division. The 820th Armor Corps will then push south between 5th and 12th Corps to achieve penetration of the defensive line.

The strike markers this turn should help out the allies a bit. Things looked grim for a moment when 2ID's brigade got beat back by 5th Corps and a hole opened up in the line. This will force all other ROK units to fall back. If the 820th gets through it will be chaos.

Supporting Attack
1st Corps's job is to facilitate the 108th Mech Corps' penetration and westerly turn. So far so good, but destroying these ROK divisions in the mountains is not easy, and the ROK 23rd Division is putting fires onto the coastal road, slowing the 108th's advance. Once the 108th gets through, 1st Corps may need to help defend it against the 82nd Airborne - if indeed that formation remains in South Korea.

The ROKs have few options here. They will stay in place and continue to delay the 108th. Two of the ROK 2nd Corps' divisions, the 15th and 7th, are effectively pinned in place, preventing the NK 806th Mech Corps from zipping down open roads. If and when the 806th gets committed to the Main Attack, all of the ROK 2nd Corps' assets can move to delay the 108th.

Losses
So far the North Koreans have lost only two light infantry brigades. The dice have been very kind to the North. But the tide will start to turn as the Allies (inevitably) establish control of the air and the North runs out of SCUDs.

Allied Counter Offensive
The North is putting up a fierce defense of the seas, making it still too dangerous to land troops. Getting control of the seas is taking longer than the Allies would like. Already, discussions are underway as to whether or not to commit the 82nd Airborne within the ROK, rather than have it participate in the attack at Wonsan.

The dice have been extremely kind to North Korea. Too kind, it's a bit odd. Every combat is resulting in losses only for the defenders. As of the end of GT3, the North's losses are up to 3x light infantry brigades, one of which was destroyed trying to take an airfield deep in the South.

The other area North Korea has been lucky, is with the Sea Control rolls. GT4 will be starting, and both "At Sea" boxes are still NK controlled.

The aggregate effect of the North's good luck, has been to wreck the Allies' original plan, ie defend in the South just a few turns until the US can lead a counter-offensive by taking Wonsan and then heading toward Pyongyang. The North has penetrated the DMZ with nearly all its combat power intact, and one of the North's rear area corps has already moved South to defend the Wonsan area. Taking Wonsan and securing the port and/or airport will no longer be easy, and in any case the units assigned to the counter-offensive are now desperately needed in the South to bolster a quickly crumbling defense.

I've also really stacked the odds against the Allies by nuking Pusan (this is wrecking the Allies' ability to put planes in the skies, which is critical to balancing the North's advantage on the ground - and also which is delaying heavier reinforcements like 2ID's Stryker BDE), and allowing the North to use chem. I've also not allowed the Allies to use their chem, nor have I allowed Japanese ground forces to assist.

GT3, End of Turn
Main Attack
"GAS! GAS! GAS!" A couple motorized infantry divisions destroyed a ROK division with the help of a little something special. Most of the text is on the map.

Supporting Attack
Most of the text is on the map. The ROK division that has been firing artillery onto the coastal road and slowing the 108th' southward movement is surrounded and in dire straits. Not sure if there is any way to save it, particularly since NK will have the initiative for GT4. The 82nd moved up, but was afraid to take a position on any flat ground against the mechanized forces of the 108th.

Allie Counter Offensive
Looks like this has been called off. The 82nd, which was originally intended to participate in an assault on Wonsan, was committed to defending against the 108th Mechanized Corps. There are a whole lot of Marines out there on ships at the moment and had also been intended to take Wonsan, but they are needed in the South unless the Allies around Seoul pull of a miracle and stop the NKs there.




Weather
o Overcast again

Initiative
o NK got 6 VP last turn, ROKs got none, making this a CONTESTED turn, ROKs go first.
o ROKs suffer Aviation Maintenance Problems, consigning removing one PM from those available this turn; North Koreans get Additional Vertical Lift Allotted, earning two more airmobile points this turn.

• Electronic Detection
o ROKs play cyber chit, which succeeds and survives, giving the allies a -2 DRM to the detection rolls. Allies detect the HQ of 5th Corps and the 108th.
o Norks detect the HQ of 2ID!

Air/Naval Phase
o Norks get 3 “Type A” PMs, and 1 “Type B” PM. ROK cyber attacks attempt but fail to reduce the number of these chits. The cyber chit survives.
o Allies get 5 “Type A” PMs, and 2 “Type B” PMs, based on the rolls and the presence of the CVN. All of these go into the “Ready Draw”. Then, because Pusan has been nuked, 2 random PMs are taken out (these turned out to be Type A!). Then, because an airbase was destroyed, one more random PM is removed (a Type B). End result, is the Allies have 3 Type A and 1 Type B in the Ready Draw. Norks have the same. Air is Contested.
o North Korea maintains control of the seas still!

2nd SOF Phase
o North Korean SOF conducts against 6th Corps HQ in Uijeognbu but fails and survives. Three SOF attacks allocated against two ROK supply depots opposite the Supporting Attack. Net result is no detection or damage to the depots, and one SOF team is lost.
o Allies allocate three SOF teams each against two Supply Depots, one supporting the Main Attack and one the Supporting Attack. No results, no losses.

1st Strike Phase
o NK launches a second series of salvos at airfields, using five SCUD points. NK has three left. Strike 2 on Daejon Airbase, no collateral. Wonju Airbase is destroyed, loss of airmobile point and 2x PMs from the Available Draw. Strike 1 Marker on Jeomchon Airbase, no collateral.
o North Korean Air: 2x PMs attack Daegu airbase, destroying it while avoiding any losses to the attackers. 2x additional North Korean PMs are reserved for CAS for the Main Attack.
o Allies Air: put a Strike 1 on Ongjin Air Base and a Strike 1 marker on 5th Corps HQ, meaning that HQ has no ability to support combat this turn.
o North Korean HQ: GHQ fires SSMs against 2ID HQ (which was detected electronically) but no effect. Other forward HQs place a couple Srike markers on ROK units in the Holding Action area, just north of Seoul.
o Allies HQ: JHQ ups the damage to 5th Corps HQ to a Strike 2, nearly destroying it. ROK 3rd Corps HQ and 2ID HQ together put a Strike 2 on a NK division at the vanguard of the attack. Similarly, the 1st Corps HQ leading the North Korean attack in the east gains a Strike 2 marker.

1st Supply Phase
o Nothing major here, but the Allies expended 2x supply points trying to resupply the 7th Corps divisions defending in the mountains in the northeast. The full strength division received supplies but nothing got through to the reduced strength division.

Basic Movement and Combat Phase
o North Korean Segment
1.All hell breaks loose on the ROK’s 26th Mech Division. All of 5th Corps, a light infantry brigade, and two artillery brigades attack with CAS (lucky rolls won’t stop for NK, and the CAS yielded a -4 DRM). The Mech Division defended with support from a ROK attack helicopoter unit and its HQs. Column was 10, -6 DRM. Rolled a 2. BOOM! Unbelievable.
2.The infantry elements of North Korea’s 12th Corps, supported by 2x light infantry brigades and one artillery brigade destroy the ROK’s 11th Division. The North used chemical rounds fired from the divisional arty.
3.A massive assault by 1st Corps against a single, out of supply and reduced ROK 8th Corps division ends as expected. No more ROK division.

o Allies Segment
1.No attacks, but the 82nd is now being committed to defense in the NE and will not wait for a counter-offensive.

Isolation Phase
o ROK 23rd Division, last of the 8th Corps, is now isolated in their mountain redoubt but pass their efficiency test. Whew.

Reinforcement and Replacement
o Nothing much noteworthy, except that the Marines made it on time, but the Stryker BDE of 2ID was delayed due to Pusan’s having been nuked.

The North Koreans still have five uncommitted corps and they are through the DMZ in the middle half of Korea. Very impressive! The South is in trouble northeast of Seoul.

GT4, Just Before Initiative Combat
Main Attack
Allied air is quickly growing into a serious threat. The North is out of SCUDs, and the ROK and US air forces are getting fully spun up. SSM, air, and helo strikes wreak havoc on the North Korean breakthrough. Supply lines are disrupted for all units at the vanguard of the attack. SSM and air strikes destroy the North's 5th Division, which had been at the very point of the spear. And worse, the Korean CIA and US activated Combined Plan TP Bluebird. A highly placed asset within the 5th Corps HQ staff transmitted real up to date, exact targeting information that supported a devastating US cruise missile attack, destroying the 5th Corps HQ. (This was the Allies random event this turn, it allowed a bonus SOF mission with a -2DRM which I used to put 5th Corps into T-1 targeted status. It had already been electronically detected.) 5th Corps is in disarray.

Nevertheless, the word from Pyongyang is "ADVANCE ADVANCE ADVANCE!". Time is not on the North's side. Allied air attacks will only get worse.

The Allies probably do not have the combat power to take advantage of the situation in the North's Main Attack. . . but they may try anyway. Remaining on the defensive is no way to win.

Supporting Attack
The North achieved spectacular success here in the first couple days, but then got bogged down after the defending ROK units from 8th Corps retreated into the mountains. That one isolated ROK division is in just the perfect spot to slow movement down the coastal road. Allied strikes made one of the supporting artillery brigades combat ineffective this turn, and the 1st Corps HQ is similarly unable to effectively support combat ops this turn. Pyongyang is screaming "You must advance!", but the commander of the 108th is afraid to give up unit formation integrity, and this is slowing his advance.

The North Koreans seem to be in really great shape. Losing that HQ is a pain but it can be rebuilt. That hole in the Allies lines looks very inviting for the mass of North Korean mechanized units.

Just wondering why you haven't sent in the 425th and PYG Corps? In my opinion both are better on the attack.

I am using the 425th is the strategic reserve. Earlier in the game, North Korea does not known where the Marines will land and where the Marines will go. In this game, the Norths 7th Corps has been able to defend the east coast, but in a game where the North has less luck with the combat rolls, 7th Corps would have needed to relieve 1st Corps in the supporting attack after 1st Corps penetrates the DMZ, because 1st Corps would have been chewed up. This would have left the east coast open to the Marines. It's handy to have a mobile force able to blunt a Marine invasion. PYG Corps is left in place to provide dedicated defense of Pyongyang in the event the Americans manage to air insert a significant force. If left undefended, Pyongyang would present a tempting target for a force of the 82nd and 101st. Supplying those inserted units becomes a challenge, but if a beachhead is created, that problem is solved. If Pyonagyang were to become seriously threatened, the North would need to shift combat power from its front lines, disrupting the attack. Leaving the 425th and PYG Corps in place lets the North handle an Allied counter offensive while continuing to press the ROKs.

US units, backed by air support, can really chew through North Korea units. North Korea has to be careful.

Another reason for not sending in the 425th, is that maneuver space is limited as it is, down in the main and supporting attacks. It'd be tough to work in the 425th as well. I don't like to use the mech forces until the infantry can push the ROKs south into more open ground, where the mech units' maneuverability can really be leveraged.

It almost looks like the 425th and PYG Corps might sit this one out.

GT4, End of Turn
Main Attack
The North's 5th Corps, struggling due to its supplies line having been cut and its HQ destroyed by the most craven of perfidious betrayals and a hail of US cruise missiles, converges once again on 2ID's armored brigade combat team. The US fights back bitterly, but in the end it is smashed, but not before destroying one of the attacking light infantry brigades. 5th Corps Juggernaut of death then turned on and destroyed a ROK infantry division. Again, the North lost a light infantry brigade. The ROK's 6th Corps then pressed a counter-attack, during which US cyber-attacks shut down the North's "blue" force tracker, resulting in the destruction of 5th Corps' armor brigade and forcing one of 5th Corps' light infantry brigades into a long retreat. Pyongyang sends personnel and materiel to reconstitute the 5th Corps HQ.

5th Corps and 12th Corps, with support of all three artillery brigades, will concentrate their efforts toward Uijeongbu and then Namyangju, heading driving toward Seoul. As the circle around Seoul closes, the ROKs are developing some defensive depth, and the attackers will certainly incur casualties, particularly also given the increased air attacks. Speed continues to be of the essence for the attackers.

The North's 8th Corps relieves the 815th Mech Corps from its position along the forward line north of Seoul. This allows the 815th to rapidly push south through defended territory where it will turn west and attack the defending ROK line at the flank, in support of the main push by 5th and 12th Corps. The 105th's movement through the DMZ was greatly slowed by air interdiction of a key LOC. Once it makes it through, it will work with the 815th.

The 806th has swung east to penetrate the DMZ, which has been left undefended in the mountains near Hwachon when the ROK 2nd Corps was forced to shore up the defense in the east. Unless and until the Main Attack falters, the 806th's first priority is to destroy the Allied HQs to its southeast.

Rear Area Defense
The North's naval forces, particularly its subs, have so far prevented a Marine landing. This fortuitous situation, however, will not last. Knowing the naval forces can no longer hold off the US Navy, the 425th has moved east to prepare to counter the Marines. US air strikes have been hitting the North's prepared coastal defense positions north and south of Tongchon for a couple days, and the landing is expected soon.

Supporting Attack
The Allied resistance here has been far stronger than expected.

Battle for Ganghyeon
The 82nd finally saw its chance to jump into the fight, and attacked the strung out 108th as the bulk of the NK corps' maneuver elements were coming through the pass in the mountains just west of Ganghyeon. Attacking the road-bound mech forces from positions on the high-ground to the south, the 82nd inflicted heavy losses and forced the 108th to fall back. The 82nd pursued them relentlessly and destroyed one of the 108th's brigades. The 82nd then liberated the town of Ganghyeon, where the entire formation took up defensive positions. The north quickly organized a counter attack bringing a huge array of forces to bear against the 82nd: the entire remaining brigades of the 108th attacking from the north and northwest, two amphibious light infantry brigades attacking from the south (where they had established a beachhead), a supporting artillery brigade, and two gunships just off the coast. The 108th led the attack by firing chem rounds into the town, immediately followed by the artillery barrage, and then the tanks and infantry fighting vehicles moved in. The 82nd was forced to retreat under heavy fire, losing three steps and inflicting one lost step on the 108th, which then retook the town - or whatever remained of the town. As the exhausted North Korean attackers attempted to consolidate and form a defense, with everyone forced to wear their MOP gear, the Allies struck back. Two divisions of the ROK 2nd Corps attacked the two mech brigades in the town as a Japanese SAG off the coast fired in support and US cyber-attacks jammed the mech brigades' comms. The two NK mech brigades collapsed. They lost three steps (one brigade was destroyed) and were forced to retreat. The attackers lost one step, and retook the town.

Commentary
It's very interesting to see how the tenor of the fight changes as the Allies build the strength to punch back. Initially, the North can choose to apply maximum force at a point of its choosing because the Allies need to try to defend the entire DMZ. I don't have the Allies waste any combat power trying to attack back in the first few turns, because they can never concentrate the combat power to do so effectively. And in this environment, the North can be relatively risk averse. It can afford to attack only when it's ready.

But now, with US forces getting involved and with the Allied air power making gains, the Allies can indeed concentrate enough combat power to go on the offensive and what is really interesting, is this situation forces the North to take more risks and, naturally, incur more losses. The US forces have a lot of agility (with the air mobility in particular and the ability to apply close air support to any fight anywhere) on the battlefield, and the North cannot sit back and wait for the perfect opportunity. The whole situation at this point in the game gets a lot more fluid.

GT5, End of Turn
The Allied defense continues to collapse inward toward Seoul and the Allied counter-attack in the east appears to be failing. High level discussions are underway between the ROK and the US regarding the use of nuclear weapons against either Pyongyang itself or against the North Korean forces in South Korea. Far from the front, ROK special forces and ROK CIA are laying the groundwork among civil leaders for the formation of an insurgency against the North if Seoul is captured. (The Korean Freedom Brigade - they'd conduct terrorist attacks throughout the peninsula and in China and Russia too while their political arm would establish a government in exile in Japan.)

The ROK has now agreed to full involvement by the Japanese, including the deployment of ground troops and the provision of combat supplies. A Japanese airborne brigade has already arrived at Suwon.

Main Attack
Rear area corps are moving forward as the North prepares for a full court press against Seoul. Once all forces are in place, 2nd and 4th Corps will shift from their holding action to active offenses, driving south. The North's 5th and 12th Corps continue to punch hard, with the support of the North's artillery brigades, pushing back a ROK division and a Stryker BDE that had been occupying a key piece of ground along the North's primary axis of approach.

The North's 820th and 806th Mechanized Corps are moving into positions to attack (it's taken the 806th a long time to clear a path through the DMZ).

US cyber actors infiltrated the North's C2 network (-2 DRM to detection rolls) and also shut down portions of the North's air-defense network (increased the AWACS advantage by one, and ensured no North Korean air units would be in play).

Supporting Attack
The 108th has suffered terribly, and its HQ element barely survived a surprise attack by the Marines. The 425th Mechanized Corps has moved south to lead the attack against the Marines from the North as elements of the 108th also prepare to attack from the south. 1st Corps takes positions in the mountains to ensure the ROK 2nd Corps and 82nd Airborne are unable to support the Marines. The North's success at suppressing Allied sortie generation helped tremendously be ensuring the counter-attacking Marines (and 82nd/ROK 2nd Corps) did not have any air support.

North Korean Suppression of Allied Air
The Allies had terrible luck here. It's GT5 and I had planned on the Allies having a lot of air support. Unfortunately, I rolled a "9" for the first roll to determine how many Type A PMs the Allies would get. BAD LUCK! And then, the Allies' random event was "Aviation Maintenance Problems", which removed one PM. THEN North Korean SOF attacks removed a few more PMs due to collateral damage rolls when the airbases/airfields took strike markers. . . after all was said and done, I think the Allies only had two Type B and two Type A PMs. Not great, and all were allocated toward Strikes in defending against the North's main attack. Those strikes were effective, but the lack of air support in the east really hurt, and possibly doomed, the counter-attack. Some CAS for the defending units would be nice too . . . haven't had that yet for the Allies, other than the attack helos.

Reinforcements
In addition to the problems caused by having had Pusan nuked, the Allies failed their roll and the entire force flow is delayed one turn. Elements of the 101st should have arrived . . . time is of the essence, because the North is advancing very quickly now against Seoul.

Next turn will be an Allied initiative turn, maybe that will help. The Allies just need a decent roll for air support for once. At least the North's SCUDs are done now.

VPs:
ROK: 88
NK: 63

Very impressive gains by the North Koreans! That hole in the line is enormous. You Sir are a much better general than I; never could get very far with the North Koreans. Next few turns could be real bad for the Allies.

North Korean Plan to Capture Seoul
North Korea will commit ten corps to the attack on Seoul. The objective is to seize control of all areas of Seoul north of the river. The ten corps will operate in three sectors. Each sector has one corps as the reserve. Once an online corps gets beat up, it will rotate off the line to be rebuilt and the reserve will step in.

Each sector has its own designated area of Seoul it must seize. Once all three sectors have achieved their goals, the fourth and southernmost area (but still north of the river) of Seoul will be taken.

Sector A
This is the weakest sector, with 3rd Corps being comprised, in part, of reserve elements not fully equipped with the best equipment. Also, this sector needs to cross the DMZ, and these North Korean corps have been engaged since day one in artillery duels with the opposing ROK forces and have a few bruised units to show for it.

Sector B
This sector has the widest frontage, and hence the most corps. This sector will also be supported by all three artillery brigades. In order to maintain clear LOCs, they will need to spend time clearing the cities of Guri and Namyangju, unfortunately.

Sector C
These are all the mechanized corps. This sector is responsible for taking Hanam in order to maintain a clear LOC. The current plan already accounts for the fact the 815th needs to be rotated offline, replaced by the 806th, due to its HQ being destroyed.


Phase 1
Sectors B and C push forward. Once they get closer to Seoul, the ROK units manning the DMZ will be forced to fall back toward the city. When this happens, Phase 2 starts.

Phase 2
Sector B continues forward toward its objective.

One of the corps from Sector C will attempt to use the ring road around the capital to cut off the ROK units north of the city and trap them between Seoul and the units in Sector A.

Sector A will move forward. Some artillery support will be shifted from Sector B to Sector A.

For the first few turns, while the North was crossing the DMZ, combat rolls were consistently and outrageously favorable to the North. I almost started over, it was getting so crazy. Just bad luck for the Allies.

Aside from that, nuking Pusan has been a killer. For instance, I just did the Air phase for GT6, and the initial rolls for the Allies would have given them 26 package markers. But after accounting for damaged airbases, and THEN accounting for a nuked Pusan, they only got to keep 10 package markers. So less then half. And then getting the heavier reinforcements takes a bit longer.

I can't really see a good plan for the Allies at this point. I guess they can focus on defeating the North in the east so those US forces out there can finally turn against the North's forces attacking Seoul. But the North has a lot of units out there in the east and after fighting them, the US might not have a lot of combat power left with which to press a counter attack.

GT6, Just Before Initiative Combat
GT6 is a ROK initiative turn.


Main Attack (aka Operation Paekdusan)
Sector A
Still holding and exchanging artillery fire with the ROKs in the DMZ.

Sector B
Allied ISR detects the HQs of both the 5th and 8th Corps. In a terrible mistake attributed to the fog of war, the North prepares to attack Uijoengbu, which is surrounded by prepared defenses. Instead, preparations should have been made to attack toward Namyangju to the south.

Sector C
806th and the 820th are moving into position, hoping to strike the ROK reserve units before the Capital Command is able reinforce those positions. The ground the two mech corps will need to cover is not the most conducive to large mechanized operations, and in particular the 820th will need to cross the river as well. If they move too slow, their attacks won't have a chance.

Supporting Attack (aka ROK Counter Attack)
Units are firing all over the place and coordinating operations has grown near impossible for both sides. It's an all out bar brawl. If nothing else, the Allies succeeded in completely stalling the North's supporting attack. The ambush of the 108th, by the 82nd Airborne and the ROK 2nd Corps, really hurt the North's efforts here.

That being said, it'll be a miracle if the Allies are able to break out of this mess with enough combat power to actually mount a counter-attack and relieve some of the pressure on Seoul.

Air Fight
ROK (of course) now have air superiority. This turn, based on the first rolls for the number of package markers, the Allies would have gotten 26 of them! BUT, I had to remove 7x of those PMs due to damaged airbases/airfields and THEN had to remove another 9x because Pusan was a smoking irradiated hole. But those 10x remaining PMs have already helped , particularly by blasting those artillery brigades. AND there is still some aircraft available for close air support finally!

Cyberwar
I think all of the North's cyber chits were gone by the end of turn 4. In any case, at this point, the Allies nearly always succeed in their cyber attacks and that is helping a lot.

GT6, End of Turn
Main Attack
Operation Paekdusan is basically a war of attrition at this point - not a lot of maneuvering going on. And as the North compresses the Allied defenders, the density of defenders is increasing and the defender's ability to reinforce weak points grows in efficiency - at least until the defenders run out of units.


Sector A
Holding. One of 4th Corps light infantry brigades was destroyed by persistent Apaches attacks followed by an assault conducted by ROK Marines.

Sector B
This is the main effort of Operation Paekdusan. So far, not doing too good. The assault on Uijeongbu failed, and one of the artillery brigades sustained quite a bit of damage from air strikes.

Sector C
The 820th moved too slowly and seems, at least for now, to have lost the chance to easily cross the river. The 806th, on the other hand made some nice progress. Sector C now has to contend with the ROK Capital Command, and this will be a tough fight.

Supporting Attack
The road along the coast and the east-west round between the mountain ranges turned into a massive ambush. The Navy's support fire helped the Allies immensely. The North's 1st Corps is still in some danger of being completely isolated, and the situation with the off-shore support has forced the 425th to swing around to the western side of the mountains. The US 101st is likely to be deployed up here, and the North is under some pressure to destroy the Allies counter-attack forces before they grow too large.

Next turn will be contested. ROKs had 27 25 VPs, North just barely squeaked by with 24 at the very end of the turn after earning 3 VP because a ROK reserve unit tried to form on Suwon, which the 820th had just cleared. Bad luck for the Allies. Only 24 points were needed to win initiative for GT7, and the ROKs would have had it, were it not for that pesky ROK reserve division in Suwon.

Battle for Suwon

There were still Apaches on the ground refueling when the first rounds began screeching overhead and tearing up the earth and tarmac. The squadrons here had been running ops nonstop and were not prepared for the evacuation. Many aircraft were told while in the air they could not return to Suwon, because Suwon would not belong to the ROK much longer. Some of those aircraft were already inbound to Suwon and did not have enough fuel left to make the trip to the either relocation point at Incheon or Cheongju. Those aircraft had to land at Suwon anyway. The sustainment element would be the last to leave. Fueling aircraft while under artillery fire was not in line with the safety regs, but the alternative was quite a bit bleaker.

After 15 minutes of bombardment with 152mm shells and 120mm mortars, the base defense saw the first dismounted enemy infantry moving along the hills only a few hundred meters away, at which point smaller caliber mortars began raining down along with heavy machine gun fire almost immediately supported by 30mm cannons on the infantry fighting vehicles that came into view on the roads approaching the base along three axis. The ROK defenders fired what few crew served weapons they had, killing some of the North Korean armor. These positions then drew fire from the North Korean tanks that had been approaching in an over-watch position but now we're racing forward. One of the aircraft jerked violently to the side as it took off, its rotor hit by a mortar round while it was just a couple stories off the ground. The Apache's tail then spun upwards and the aircraft plunged into the ground. The base defenders managed to stave off the tanks for about ten minutes before they were over-run. It was just enough time for the bulk of the aircraft to escape.

It was only a few days ago that North Korean SOF teams had terrorized the area, attacking the airbases and airfields nearby, lighting the night sky with explosions that rattled windows on the edge of the city. Now the sound of explosions just to the east rumbled continuously through the streets as the Suwon airbase fell under attack. Civil defense personnel raced through the streets alerting anyone able to leave immediately. The reserve unit here had begun organizing nearly as soon as hostilities erupted a couple weeks ago. Now any deference paid to the by-the-book procedures was tossed aside, and reservists raced to draw equipment from the Suwon reserve armory and organize ad hoc combined arms fire teams even as the 820th barreled into the city. It soon became obvious that to stay and fight was to die pointlessly. The ROKs defended as best they could, mounting a disorganized defense and trying to slow the North's advance through the city just long enough for some of the ROK vehicles and personnel to escape north into Seoul. Most of the ROK tanks (older model M48s) left as soon as they had fuel, without even waiting to load rounds for the main gun. One tank that did load up managed at least to wreck the tracks of two North Korean infantry fighting vehicles that did not expect to take fire, before itself exploding in flame after a North Korean sabot round passed completely through its body, hitting the fuel reservoir along the way.

(The clearing marker for the Suwon hex was a 6. And since the airbase and city are both on the same hex, this made failure a definite possibility. The north was a bit lucky to have succeeded in the clearing operation in one roll. The airbase just to the north is in trouble next.)

Allies: 113
NK: 87


Allies got a 50 VP boost at the beginning due to Pusan getting nuked, plus a few extra here and there due to the North's use of chem.

The tracker shows the North still has SCUDs, but I forgot to move the marker. NK used them all up in GT4 I think.
