I was wondering about this, and would appreciate clarification.
AT and infantry guns are considered rear area units, therefor when they are coupled with infantry and other front line troops they will have an increases survivability if i understand this correctly. So my question is this, if i have an anti-tank brigade (10 at guns 5 trucks) with no infantry but in the same hex as an infantry division (say 40 inf, 10 mg, etc..) will the AT guns get the rear area protection from infantry not in the same formation but in the same hex? On the battle screen, it shows the two formations in separate columns so i wonder if this is the case. I have been trying a new strategy of having my AT guns separate from infantry and mobile, so that i can mass them where they are most needed and save production cost on having AT guns in all inf. units. If i don't get the rear area bonus though, this strategy obviously wont work.
Also, since artillery is rear area i was wondering if anyone has experimented with keeping them in their formations themselves, rather then behind. I would think they are too expensive to risk, but i would imagine it would give quite a boost to the unit's firepower. Also, in stalemate, your units would be able to attack with the artillery to reduce the organization, strength, and moral of the units they face, keeping the enemy on the defensive. Saves on the few PP for the extra artillery groups, but if you use the barrage your unit is no longer available to attack or move. Your thoughts?
