Tactical Training and a Permanent Home
Marine Corps Air Ground Combat Center (MCAGCC) Twentynine Palms is the permanent home of Fleet Marine Force units and is a key live-fire training location. The location, near the San Bernardino Mountains, provides ideal terrain for Marines to practice live-fire maneuvers.
Twentynine Palms was commissioned in 1952 in response to the need for more live-fire ranges during the Korean War. Following the completion of an expeditionary airfield, the base was redesigned as Marine Corps Air Ground Combat Center in 1979.
