How in the world could you be a REMF if you're taking rockets, Sarge?
The answer is this:
Most people think that "REAL soldiers" are only the trigger pullers and door-kickers, and SOF/Ranger/Delta/Marines. And that any other guy in uniform is wasting oxygen.
But the Fobbits? We just sit here behind the wire. We have showers and A/C. We have food in a mess hall. We do shift work, then we retire to our bunks. We even have Internet. We're not real soldiers.
But the rockets and mortars reach everywhere. There's no place to hide. And behind the wire, it's a bullseye for Them. We have nowhere to run. And we don't have the firepower to shoot back.
So we sit here and take it. From Them, and from our own. The miitary eats its young.
