The M855 5.56 NATO that we use in the military is actually more than capable of penetrating Class IIIA body armor. There's also the fact that you don't go around trying to shoot people through walls. That's how noncombatants get shot and you end up having a dead child on your concience the rest of your life or some other such thing. The only time you pull the trigger during a MOUT operation, or any other operation, is when you have positive ID on the target. Running around trying to shoot people through walls is a violation of the US's ROE and all it's going to do is eventually end up with dead COBs (civilians on the battlefield) and in the right circumstances with you in prison. There goes the whole "winning hearts and minds" thing if that shit starts happening.Ben said:I think they do need something with more power for modern combat situations though, to deal with body armor and penetrating walls in MOUT operations.
