The United States Air Force's 13th Air Support Operations Squadron is a combat support unit located at Fort Carson, Colorado.

The squadron provides tactical command and control of close air support assets to US Army ground commanders of the 4th Infantry Division during combat operations.

The squadron's mission is to provide mission ready airmen to advise, integrate & control air and space power in support of the 4th Infantry Division; to train, deploy, & focus combat airpower and integrated weather operations for the joint force commander alongside III Corps or a supported land force commander.

Also, the Army Air Forces found that standard military units, based on relatively inflexible tables of organization were proving not well adapted to the training mission and decided to replace them with a more functional system in which each base was organized into a separate numbered unit.
