“In Viet Nam, the percentage of actualyoung American troops WW1, WW2 and Korea. This fact is beyond dispute.”
I think you left something out of this- it makes no sense as written....
Something didn’t copy correctly. The intended point was that the % of American troops in WW1, 2 and Korea who actually aimed at enemy soldiers and blew them away was very low. The VN-era reactive humanoid reactive targets were meant to improve that % buy conditioning a response. Round bullseye targets of previous wars didn’t do that.
