1. If my Activation range is 0-1 and the paragraph says to do an activation check +3 then I add that to the range (not my roll) and the range becomes 0-4 correct? In this case if I roll a 4 or less the roll succeeds and the German is activated. I,m pretty sure I got confused and was happy whn I did't succeed only to realize that without Germans I would have no VP.
That is correct. The modifier applies to the activation level not the die roll. The unmodified die roll is compared to the modified activation level. Any roll equal to or less than the activation level succeeds.
2. A German solider is wounded and falls prone, he looses his turn, the next round can he crouch to fire if that is his action paragraph?
He can but at a penalty. Since he's wounded the soldier would not get a free stance change so he would have to expend a movement point to change stance. Wounded soldiers have 2 movement points so he would have to expend half of those. This allows him to take a Move/Snap Fire action. At the end of this action he would not have movement points left to fall prone if instructed to do so. Wounded soldiers have a -1 combat modifier and the snap fire modifier is -2 so the soldier would have a -3 combat modifier before applying modifiers for terrain etc. Snap firing a weapon also changes the weapon jam percentages as well so be sure to take that into account if applicable.
3. If a solider is unaware can he still move around the board towards another objective that is not the German Solider?
Unaware soldiers cannot perform actions. Their counter stays in the Unaware section of the Action Round Track until they become aware on turn two or three (when automatically become aware).
4. For order of soliders in rounds do those with two actions take them one after another or take their second turn after everyone has had their first?
In rounds, all counters are activated from top to bottom. So if the Germans win initiative then their 2 Turns counters would activate first followed by US 2 Turn counters, followed by German 1 turn counters (including the counters activated previously which are now 1 Turn), followed by the US 1 Turn counters. Then any counters in the Panic boxes are moved to the Complete box and the next turn starts.
5. If I have multiple soilders on the same action track do I go in initiative order starting from 5 down, or do I choose?
For US counters in the same space you get to choose. For the Germans they go in alphabetical order. Since Germans with high initiatives have lower letters you will usually start on the right and work left. The exception to this would be some cases where a German commander is instructed to give a turn to another soldier. This may create an instance where this order would change but it doesn't happen often.
Hope that helps
