in Nam. Nobody else does, either, when being shot-at, with no ear protection, with the enemy moving, using cover, except by LUCK. Luck in a hit or miss scenario, is greater than 50% hits, for number of shots fired. Since the military fires about 50,000 rds of rifle amno for each hit that they get, and most hits are POOR hits, you are looking at 100,000 rds per GOOD hit, and they don't really do a lot of shooting with rifles, beyond easy scoped 223 range, either. So there's TONS of missing done inside 100m.
