Grenade Assault for Eiserner Wille

I thought this may be a good idea long ago and was told to post this here. Basically the idea is for something akin to the grenade assault ability in original CoH2, where the entire squad would throw grenades. This was a real tactic used by the germans and quite effective at surpressing(or sometimes killing) big groups. It was offset in the original game by requiring a lot of time out of combat(to simulate the time spent requisitioning this many grenades) but it could also of course be offset by high cost, being limited to certain infantry or being very spread out(to increase surpression but reduce damage)
