Lance Cpl. Rudy Coletto, a Marine on his first tour of duty in Baghdad's violence-wracked Tissa Nissan district, said he hopes to be reassigned to a different area of the city once his request for discharge is refused. 'After I'm told I can't leave the Corps, I hope they at least station me on a different tiny besieged island of U.S. control,' said Coletto, 24, who has defended the same 30-by-30-yard square since arriving in Iraq last Christmas. 'I was thinking maybe that one block of the Sunni district we patrol up in north Baghdad, or even that two-block section of Doura where they've almost managed to enforce the curfew.' Coletto's commanding officer said that he would almost certainly be transferred elsewhere after the Tissa Nissan base is overrun by insurgents and abandoned within the month.
