US troops wait and video record as a JDAM crushes an insurgent occupied dwelling in Iraq. You can tell these guys aren't new in country as the response to such close carnage barely excites them. They've seen it before, many times.

The JDAM (Joint Direct Attack Munition) is an aftermarket kit applied to an ordinarily “dumb” unguided bomb, which converts it into a precision guided munition. The program was jointly developed by the Air Force and Navy and is applied to 500-pound, 1,000-pound, and 2,000-pound bombs.
