Coordinates: 32°40′N 116°26′W / 32.667°N 116.433°W Mountain Warfare Training Camp Michael Monsoor (formerly known as La Posta Mountain Warfare Training Facility), located at 3,500 ft (1,100 m) elevation 50 miles (80 km) east of San Diego, near the unincorporated community of Campo, in San Diego County, is a 1,063 acres (4 km2) training facility used by the Naval Special Warfare Center.
The 1,063 acres (4 km2) site has a firing range, an administration building, barracks, and a 5,000 m length mountain endurance training course. The Navy has operated on the 1,300 acres (5 km2) plus acres since the early 1960s, and is seeking to set aside an additional 4,486 acres (18.15 km2) of federal Bureau of Land Management property for the facility. The Mountain Warfare Training Facility served as a satellite tracking station for many years until current technology made the giant tracking dishes obsolete. The property was reconfigured as a training center when the station was shut down in 1986.
In 1998, Naval Base Coronado gave permission for the Naval Special Warfare Command to use the site for mountain warfare training of the Naval Special Warfare Group One which trains its SEAL and SDV teams there, and conducts BUD/S classes.
