The Marine Corp snipers were the most deadly and cost effective weapon used in Nam. This is why the brass ignored them and tried bury their accomplishments.
A friend of mine did 3 tours as a LARP sniper with the Corp in Nam. He had bounties on his head from the Viet Cong, the ChiComs and the Russians. He never talks about his actions and accomplishments. The three bounties say all that is needed be said. The enemies knew how effective he was.
Another great warrior who deserves more recognition than will ever happen. What a strange sort of prejudice the military has toward these men. Somehow it's legit to designate the targets they are given, but not acknowledge the great significance of their achievements.
I believe only those who have fought the enemy on the ground - and seen them - appreciate these men.
