1 - If I understand correctly CWC in ground combat seems to help only the attacker (no column left shift for defender), correct ? if yes, why not at least a +1 dr modifier (a sort of attack coordination light disruption) ?According to the rules, you are correct. I am sure Mitch will chime in about his thinking at some point.
2 - using the new alternate air system (PMs) in 1.2.5 first dot:
"remove ... one for each Airbase Captured/Destroyed in the last turn or in this turn’s First SOF Phase"
so no PM is removed for Airbase destroyed in previous turns, if I am in T4 destroyed in T2 and T1, correct ? again if yes, why (in consideration of second dot (strike markers) ?
Yes, on Turn 4, no PM is removed for Airbases/Airfields destroyed on Turns 1 and 2. This mimics Advanced Air Game and the enemy player getting to choose Air Units to move from Ready to Flown. The temporary effect represents planes rebasing to other Airbases/Airfields after a delay.
3 - using the new alternate air system (PMs) how can I shift the AWACS adv marker ?Using the Air Superiority difference as normal in the Advanced Air Rules.
4 - using the new alternate air system (PMs) how can I use the CWCs in 1 & 2 Strike Ph (1.3.5) ? I don't see any way to use them in the Alternate Air Rules, therefore that only applies to the regular Advanced Air Rules.
