I'm not on AGW, but a Marine Master Sniper, who's also a good friend of mine, teaches our precision rifle, police marksman, and sniper courses for our school/training facility here.
He was deployed in Iraq with the 1st Marine Division, and taught at the sniper school as well as the mountain warfare school.
I've shot with pretty much every Tier 1 type soldier around here at the school and Sigarms Academy (I'm a Tac Conceal Pistol Instructor with Sig), and our x-Marine is by far and away the best most meticulous rifle shooter I've ever met.
There's a good reason that Delta and the Teams train at the Marine sniper schools.
P.S., his confirmed count is 47, and he told me he did another 100+, and I believe it.
