Maybe not end it, but perhaps make life a little harder for the enemy. Here goes:
We take the AK brass that is littering the countryside and clean it up, then reload it for them. Only some of it is not full of powder, it is loaded with either a high explosive to destroy their action or perhaps thermite to melt it to worthlessness? We leave this stuff somewhere for a traiterous iraqi soldier or policemen to steal to give to his al qaida buddies. We do this a lot and sooner or later they've destroyed a bunch of rifles and don't kow if their rifle is going to work when they need it to. Maybe we could leave RPG rounds laying about with a fuse set to detonate upon attempted launch.
