[NVSmith]

-I went through basic training at Ft. Gordon, GA, in the summer of 1963. We used the M-1 and qualfied using the standard course of fire out to 600 yards.
-We had a one hour block of instruction on the M-14 and were told not to worry about it because we would probably never see one again.
-A few months later I was in RVN carrying an M-14 but never qualified until after my tour was up and I went to Ft Dix. I think the max range was 300 meters. I never saw an M-16 during my first tour but we did have Colt marked AR-15s with "Property of US Government" stamped on them. They had the funny brownish furniture.
-We had M-14s and M-16s on my second tour but, again, no qualification. I finally qualified with the M-16 years later in the Reserves on that stupid 25 meter target.
