Why, do people think G43's are bad on Panzergrenadiers? They increase mid and almost double long range damage, and has better move accuracy. You are able to move in closer while still dishing out a large amount of damage. Personally, I have had a G43 PG beat two Rifles at long range, all in light cover.
STG 44 close :15.78
STG 44 Far: 1.86
G43 close: 14.73
G43: 3.26
Grenadier's MG 42 Close: 7.66
Far: 7.19
With the 2 G43s on PG you are almost doing as much damage as grenadier with a mg 42. Not only G43s are cheaper they can move and shoot, so in my opinion they are better than mg 42.
