Misunderstood then, apologies. MG42 on grens still seems like a better idea than G43's which are a close range weapon (and shocks excel at that range)
G43 are Mid Range Weapons, also when dealt enough damage, can already snipe one of the models.. then it will be ping .. ping..ping.. schocks down to 3 men when they reach you, or your opponent retreats before (That is of course the "best case scenario").
