GG,
If you had ever had to fire a shot at a soldier who was trying to do the same to you,then you would know why 5.56mm is a poor subsitute to the 7.62NATO!
Damn for firing past 400meters! I'll be calling for 11C(mortarman)or arty "danger-close"!
For dug-in or bunkers we use to carry the M67 90mm recoilless-rifle.
Oh yea,forget about the US manufactured 7.62NATO!
Give me the German Ammo!
That kraut 7.62NATO uses mild-steel jacket bullets that break apart better than any 5.56mm!
Urban combat with barriers has the 7.62NATO hands down better than any 5.56mm load can produce!
