“Vietnam . . . A Marine walking point for his unit during Operation Macon, a marine moves slowly, cautious of enemy pitfalls . . .”

By an unknown photographer, 1966

‘“Walking point” on patrol in Vietnam meant being the first to face ambush, sniper fire, or booby traps. According to one account, this duty meant a man needed to develop a “sixth sense for danger” in order to protect himself and his comrades.
