U.S. troops had this problems when they were transitioning to the M16 from the M14 rifle. One U.S. soldier I met after Vietnam (he was paralyzed by a mortar), said he wanted to keep the M14. M14 was good, it had a better knock down component than the lighter .222 of the M16. M16's problems were finally ironed out--mostly. Still is this our problem today also? We need more troops if we are sending in minimal forces to engage the enemy. But, do we end up like the Russians?
