come on lads, use your noggin's... there are plaenty of non/less than lethal combat systems used. weapons such as tear gas grenade launchers count don't they? what about the arwen non lethal projectile gun... can fire an array of non-lethal munitions including crowd control gasses and rubber baton rounds (bloody hurt actually, had that welt for five weeks... don't ask). another could be the MGL (multiple grenade launcher) which is desinged for both lethal and less than lethal projectiles. and ofcourse theres the simple 12 bore bean bag rounds for any shotgun from a 870 to a spas 12.

after writing this i've realsied that it's all pending on what you mean by war. if it's just plain and simple war then it's likely that the above systems aren't going to be seen but in terms of unconventional warfare well that's a more likely application for these and the numerous other systems i can't remember the names of. hope this helps
