If no-one else noticed assault commandoes have a grenade that is in terms of stats looks identical to volks/vsturms. Can they have ranger grenades or more throw range to balance for how bad this low AoE grenade is against axis inf that is usually more spread out than their allied counterparts.
Another option is to swap this grenade out for a better one with weapon training unlock making you invest into better grenades for offense or go for defensive unlocks for more effective hp+ambushes.
