Dont worry, Ekko Tek.
The survival discrepancy will become a topic soon enough.
Germans have a very good unit called Grenadiers,you should try using them once in a while,they're very good,they have good accuracy from distance,and can shoot Panzerfausts and Rifle grenades,and are even upgradeable with a Lightmachinegun...
On a serious note now,STOP USING MG42 AS A SPEARHEAD UNIT...it's called SUPPORT WEAPON TEAM for a reason...
So you want to add 6 man to an MG42,which has a wider arc and better surpression...I wonder why did Relic did not recruit you?
