1. As we all know flamethrowers shred infantry always, just send in your crocodile and infantry no more. Adding a flamethrower emplacement to the game, possibly for US faction as a backup for when your mg bunkers get destroyed OR using the flamethrower on pinned troops.

2. Russians/Soviets have very good artillery and can destroy most things in it's way and im not talking just howitzers but the mortars and KT trucks. What Soviets lack is a basic anti tank structure and i think the kv-2 would fit perfect. i believe it uses the howitzer rounds which again refers to howitzers. Obviously it has to have a weakness and yes, slow turret rotation and slow reloading balance it out.

3. Not sure if it's daft or a good idea but a wooden bunker with around 2-3 snipers in. they are overkill to troops however weak to mortars/airstrikes etc.

4. Not sure about you players but i love to start a game up and just defend however about an hour in the game the AI refuse to attack and if they do it's like 1 medium tank every 5 minutes. Also when blocking the AI at first it messes how they play afterwards when they slowly push.
