The Marine Corps operates many major bases, 14 of which host operating forces, several support and training installations, as well as satellite facilities.[94] Marine Corps' bases are concentrated around the locations of the Marine Expeditionary Forces, though reserve units are scattered throughout the United States. The principal bases are Camp Pendleton on the West Coast, home to I MEF; Camp Lejeune on the East Coast, home to II MEF; and Camp Butler in Okinawa, Japan, home to III MEF.
Other important bases include air stations, recruit depots, logistics bases, and training commands. Marine Corps Air Ground Combat Center Twentynine Palms in California is the Marine Corps' largest base and home to the Corps' most complex, combined-arms, live-fire training. Marine Corps Base Quantico in Virginia is home to Marine Corps Combat Development Command, and nicknamed the "Crossroads of the Marine Corps".[95][96] Marines operate detachments at many installations owned by other branches, to better share resources, such as specialty schools. Marines are also present at, and operate many, forward bases during expeditionary operations. Finally, Marines operate a presence in the National Capital Region, with Headquarters Marine Corps scattered amongst the Pentagon, Henderson Hall, Washington Navy Yard, and Marine Barracks, Washington, D.C.
