A Good and powerful Wehrmacht coy includes only 2 units. StuGs and Volks. Perhaps 2 - 3 MG42s is acceptable.
One of the best games of EIRR that i've had was a 3v3 with Nightrain and someone, we all fielded 10 stugs and 26 volks squads each. Nothing more, nothing less.
How to counter 30 stugs and 78 squads of volks with assault nades?
