Graffiti left behind by Taliban fighters remains on the walls of a compound now used as a command center for the U.S Marine Corps's First Battalion, Eighth Marines at Musa Qala in southern Afghanistan's Helmand province, November 10, 2010. Musa Qala is an important battleground in the war against Taliban insurgents and the narcotics industry. The town has changed hands several times, most recently in December 2007 when Afghan and international forces retook the town from the Taliban.
