According to this article by Yahoo! News: Soldiers wounded in Iraq stay in Iraq or return to Iraq. Some have been injured a number of times. Some are in pain. Some are suffering from the consequences of injury. But they’re still in Iraq. They chose to return or stay in Iraq. They’re there by choice.
I can't understand this. But seeing their dedication, it makes some sense. In any case, they certainly make me feel very, very small.
Bravo to them all. May God bless them.
