Conscripts will start out normal as they do every game. Once T3 is reached, an upgrade will be available in that building. The upgrade will outfit all Conscript squads, old and new, with three PPSh-41 Submachine Guns. These PPSh's will be unique among SMG's in that they will not reduce DPS at any range, only increase it at closer ranges. I'd imagine it would have a similar damage curve (Not DPS) to the Thompson. When the upgrade is purchased, instead of showing the PPSh weapon icon, all Conscript Squad icons will change to this:

That will allow you to still see what other weapons you have picked up or upgraded, instead of being hidden by a PPSh icon. This would support the role of Conscripts as aggressive close-mid range units without hindering their alternative role as long-range defenders from cover. As for the Commander ability, replace it with an SVT-40 upgrade similar to Panzerfusilier's G43's, 3 semi-automatic rifles that are useful, but not too strong.
