The idea of your calliope is like me. Opinion is right. The idea of rifle squad seems a little different. I question the combat power of the rifle squad because they have a lot of bad parts when they deal with OKW.
In fact 1xBAR Riflemen can beat STG44Volks at all range,OKW hard to deal in early game because they have StormPioneer at start
And if increase M1 damage to 10,max range dps will same as Grenadier k98 and more high in close-medium range,and Riflemen is 5 men squad with more Vet bonus than Ost and OKW mainline infantry
