Re: This looks interesting....will this be a big help?
I can certainly see the benefit of the XM25, however there are a lot of factors which detract from the benefits.
#1, this will not be a primary weapon, so the rifleman carrying this will have to carry this thing, it's ammunition, spare battery AND his standard load-out.
#2, Ammunition costs are likely very high- this will limit live-round training and may even prove to be a limiting factor in use.
#3, I can see some commanders being wary of using a defilade defeating weapon for fear of injuring or killing "non-combatants" in the same space as the enemy. Right or wrong, it will happen.
Over-all, I would call it much more useful if it were smaller or somehow attached to an M4 like the M203.
