Latin Gangs in Iraq?

Thats what the Chicago Sun-Times is reporting:

Armored vehicles, concrete barricades and bathroom walls all have served as canvasses for their spray-painted gang art. At Camp Cedar II, about 185 miles southeast of Baghdad, a guard shack was recently defaced with "GDN" for Gangster Disciple Nation, along with the gang's six-pointed star and the word "Chitown," a soldier who photographed it said.
The graffiti, captured on film by an Army Reservist and provided to the Chicago Sun-Times, highlights increasing gang activity in the Army in the United States and overseas, some experts say.
