Found this article *excerpt* about Al Queda incorporating american training tactics into their training....including sniping..
"It had been cribbed from an appendix in a Marine Corps manual seeking to standardize sniper training, a copy of which was found with terrorist course schedules in a Harkat house in Kabul."

Would Ali Mohamed, who spent so much time at Ft. Bragg and who was largely responsible for developing the al Qaeda training program, have gone through sniper training in the U.S.?
