Also, I would suggest to exchange two abilityes:
-"Za Rodinu!" - attack rush of Command Squad
-"Red Banner" rush of Strelki.
Logically, there must be only 1 Red Banner per player, wich supposed to be a Banner of Company. And it is more really and logically to give that "man with banner" to Command squad (wich supposed to be "curfew platoon" - "Banner Guard Platoon").
And with Strelki - instead of "man with banner" after upgrade, Officer could be added, with ability "Za Rodinu" - "attack rush".
