M1918 is most likely placeholder due Tunesia testing like the British stuff. The M1918 squad in Russia could be a placeholder until they replace them with Italian ones as the snail is lazy as fuck with uniforms (cough German paras cough). What will happen after that is up to Darkflow.
Chauchat saw limited usage by the Soviet during the first part of the Invasion so its deversed to be a premium gun. Scoped G41 could be a premium as well but guess its would be unfair for ze poor wehraboos.
Except that Soviet aside the T-60 and the T-50 doenst have armour and have like three crew members and that they have better reload time.
