U.S. units were largely restricted to a handful of small bases. The headquarters base, in the northern corner of Ramadi, is on the grounds of one of two Saddam-era palaces in the city; known first as Tactical Assembly Area Rifles and later as Camp Blue Diamond, this base was turned over to the Iraqi Army in the winter of 2007. At the other end of the stretch of Highway 10 that runs through Ramadi is another Saddam-era palace used as a Combat Outpost by a unit from the Florida National Guard. Several smaller buildings along Highway 10 between the two larger bases are routinely occupied by U.S. and Iraqi units, and just outside the city there are a number of other, less dangerous and better equipped camps, where an Army brigade headquarters and its support units were based.
