In team games you meat assgrens every match. They are dangerous and if another member go with MG42 behind, they rape conscripts easy. On other side, i have no problem deal with this, if mate support me with maxim also.
Not main infantry, but as alternative opening are good.
I was actually talking about their grenade ability, the one where I pay 45mun to halt their DPS and make the enemy breakdance and maybe kill one, then continue shooting with MP 40's because it did jack-all to change the outcome of the fight.
