Now here's something that you can sink your teeth into: Blackfive has a long, but excellent post of an After Action Report (AAR) from our Marines in Fallujah.
Read it, then come back. I'll be here.
OK. Now we've had a number of things that the LeftLoons and their lapdogs in the Legacy Media have been playing up over a period of time, trying to turn the American public against our troops and against the War on Terror. A Marine in Fallujah kills a suspected terrorist on camera, Lt. Ilario Pantano's actions in Baghdad when 2 suspected terrorists began making threatening actions, and the incident on the airport road involving a journalist for the Italian communist newspaper, Il Manifesto. (There are others, these are just the three that come immediately to mind.)
Now that you've read the AAR, a thinking person should have all their questions answered. These warriors are acting based on training and bitter experience. With near universality, their actions are correct, even while seeming "barbaric" to the Lefties, sitting in front of their 52" high-definition plasma TVs in the comfort of their over-priced living rooms in their comfortable, well-policed suburbs, listening to some media talking head explaining to them why America is Evil, why the War on Terror is Evil, why the Bad Guys are actually just misunderstood but hopeless Young Arab Men, and that if we just all join hands and sing one more freakin' verse of Kumbyah the world will suddenly flower in Peace and Understanding.
This war isn't WWI, WWII, Korea or Vietnam. It isn't even the Gulf War. It is it's own thing, fought in a different time, a different place and under different rules. Did you pick up on the part about the corpsman's shotgun? In WWII or Korea, it was very rare indeed for a corpsmen to arm himself. It was still uncommon in Vietnam. In this war, the corpsman damn well better be armed, because these people aren't playing by "the rules". An unarmed corpsman is a most tempting target indeed, because shooting him will enrage his fellows. The rules are different, and we'll have to fight by those rules in order to win.
If the AAR doesn't answer your questions on this subject, then I don't think anyone can. You can keep coming back to visit, and I'll keep trying, but I don't hold out much hope for you.
