I was in the 2/502 Inf 101st Abn Div 67-68. Each BN had a Recon Plt. I was with the Recondo's, the recon plt of the 2/502. We didn't wear helmets, we wore a black beret with the 101 Recon Patch. Useless except for wiping the sweat out of your eyes. Didn't wear the LBE either. Worked out of my ruck.
We had a sniper assigned to us for a bit, he carried a standard Model 70, in '06 with a fixed 4X Weaver, exactly like the top rifle in the below photo.
The AMU started using Model 70 Tgt Rifles in 308 in the mid to later 60s. The bottom rifle is one such rifle I got from the CMP Auction. It was Made in '65. I was set up with sight bases for an "across the course gun" and had blocks for the Unertl style scopes.
I never heard of and doubt the 308 Model 70s were used because that was about the time the AMU was fielding M21s. They were used on the rifle ranges.
Mine fields a Vortex 6-24 X 50. I use it in PR matches and HP 1000 yard any-rifle-any sight and with the Redfield Palma sights for the Any-rifle-iron-sights and a cross the course matches. Sucker shoots as good if not better then my RPR in 6.5 CM although I will confess I don't get the range with the 308 as I do with the 6.5.
I love my Winchesters, all of them.
