Fort Carson: The Army’s Mountain Warfare Laboratory

01A post shaped by terrain

Fort Carson sits directly south of Colorado Springs, with the developed post in El Paso County and additional land spanning Pueblo, Fremont and Huerfano counties. Its setting is operationally important: the post gives soldiers access to high-country conditions, broad maneuver space and the logistical problems that mountains impose on every movement.

The garrison includes the 4th Infantry Division, 10th Special Forces Group and 4th Security Force Assistance Brigade, alongside engineers, ordnance, sustainment, military police and air-support organizations. Mountain warfare is therefore a collective skill, not a niche badge.

02Camp Carson arrives in wartime

Camp Carson was established in 1942 after Pearl Harbor. Colorado Springs purchased land south of the city and donated it to the War Department; the first building, camp headquarters, was completed on January 31, 1942. The camp was named for Army scout Christopher “Kit” Carson.

Construction was a mobilization project at scale. Nearly 11,500 workers were employed at the peak, and facilities were provisioned for 35,173 enlisted men, 1,818 officers and 592 nurses. The second chart shows how heavily the original design leaned toward the enlisted force it was meant to train and deploy.

03A mountain school before the name

More than 100,000 soldiers trained at Camp Carson during World War II. The 10th Mountain Division was among the formations associated with the post, and pack mules carried equipment, weapons and supplies across mountain terrain between 1942 and 1956.

In December 1949, Strategic Air Command opened a survival school at Camp Carson for mountainous terrain. It moved to Stead Air Force Base in Nevada in 1952, but the institutional idea remained: troops must learn how cold, slope, altitude and distance change the meaning of ordinary fieldcraft.

04From camp to Fort Carson

Camp Carson was designated Fort Carson in 1954. Mechanized units arrived in the 1960s, the post expanded to roughly 137,000 acres, and Butts Army Air Field was built with a 4,573-foot runway for light fixed-wing aircraft.

The result is a hybrid training environment. Soldiers can practice dismounted movement, vehicle maneuver, aviation support, live fire and sustainment in terrain that punishes poor planning. Mountain warfare is not just climbing; it is the integration of all those systems under friction.

05Piñon Canyon and big-unit maneuver

In September 1983, an additional 235,000-acre training area was purchased about 150 miles by road to the southeast: the Piñon Canyon Maneuver Site. It is used for large force-on-force maneuver training, complementing comprehensive maneuver and live-fire training at Fort Carson itself.

The landscape scale matters. A unit that can move, communicate and resupply across wide, broken ground is practicing more than a symbolic mountain exercise. It is rehearsing the time, fuel, casualty evacuation and command problems that make terrain decisive.

06What the mountain course teaches

The embedded Business Insider video follows a 14-day Army mountain school, including winter movement, cold-weather gear, climbing, rappelling, land navigation, knot tying, casualty evacuation and a culminating event. The course illustrates a central principle: technical competence must survive fatigue and weather.

High-angle systems and rope work are visible skills, but the deeper lesson is judgment. Soldiers must choose routes, manage energy, protect equipment, and communicate when the landscape breaks line of sight and slows every decision.

07Training as readiness

Fort Carson units train annually at Piñon Canyon and the National Training Center near Barstow, California, and participate in joint exercises across Africa, Europe and Southwest Asia. Deployments and exercises turn the post’s terrain into a readiness laboratory.

Its historical continuity is unusually clear: the wartime camp trained mountain divisions, the post hosted a survival school, and the modern installation combines a heavy maneuver force, special operations and large training areas. Fort Carson’s mountain identity is therefore not branding. It is a long-running operating system for preparing soldiers to move and fight where maps, weather and gravity all resist them.
