I was with the Ft. Carson AMU unit in 1968, and later 5th. Army AMU in 69-70. During that time, we were rotating our top rifle shooters in & out of Vietnam on a regular basis.
When they were in Vietnam, they were snipers, and when they came back, they were National Match competitors.
At that point in time, both units had a very difficult time getting any GI issue sniper rifles, so we were building our own.
I know for a fact of several bull-barrel 30-06 Model 70's being pulled out of heavy 1,000 yard position stocks and dropped into Model 70 Varmint rifle stocks with a new glass bedding job. Scopes were the same Unertal & Lyman target scopes used in NRA competition.
M-14 National Match rifles were scoped with Leatherwood mounts and whatever 3-9 variables we could scrounge up, usually Redfields.
I also know of some of our .30-378 Mag 1,000 yard rifles going to Vietnam, along with a years tour-length supply of hand-loaded match ammo.
We also designed, tested, and built a few Unertal scope mounts that would fit any Browning .50 MG in Vietnam, and I can assure you, you wouldn't want one shooting at you 1 1/2 miles away.
At that time, the Army Sniper program was the same people running the AMU programs & shooting in the AMU Bullseye competition stateside, and it was a very close-knit, and closed group, both here, and over there.
The only thing I have to say is, I always thought the Marines had a much better & more vocal press spokesman in Maj. Jim Land then the Army ever had in our program.
That sucker could flat out generate some press releases for the Marines!
The Army took a much more low-key approach, and just didn't talk about it.
