United States Army North is the senior command and responsible for all Army activities on Fort Sam Houston, but not for the post itself. Commanded by Lt. Gen. John R. Evans Jr., Army North's primary missions are land-based Homeland Defense, Defense Support of Civil Authorities and Theater Security Cooperation with the Bahamas, Canada and Mexico. Because Fort Sam Houston is part of Joint Base San Antonio, the installation commander is the commander of the 502d Air Base Wing.
