Butts Army Air Field (IATA: FCS, ICAO: KFCS) is a United States Army airfield located at Fort Carson, a major Army installation near Colorado Springs, Colorado. The airfield primarily supports military aviation operations, including rotary-wing aircraft used by units stationed at Fort Carson. The facility is named in honor of a military servicemember and serves as a key operational and training airfield for Army aviation assets. As a restricted military installation, it is not open to the general public and does not support commercial airline service. Fort Carson itself is home to the 4th Infantry Division and other Army units, and Butts AAF plays an integral role in supporting their aviation requirements, including troop transport, training, and logistical missions.
