When Air National Guard units are used under the jurisdiction of the state governor they are fulfilling their militia role. However, if federalized by order of the President of the United States and they are jointly administered by the states and the National Guard Bureau, a joint bureau of the Army and Air Force that oversees the National Guard of the United States. The ANG of the territories of Guam and the Virgin Islands have no aircraft assigned, ANG units typically operate under Title 32 USC. However, when operating under Title 10 USC all ANG units are operationally-gained by an active duty USAF major command. ANG units of the Combat Air Forces based in the Continental United States, conversely, CONUS-based ANG units in the Mobility Air Forces, plus the Puerto Rico ANGs airlift wing and the Virgin Islands ANGs civil engineering squadron are gained by the Air Mobility Command. The vast majority of ANG units fall under either ACC or AMC, established under Title 10 and Title 32 of the U. S. S. When not in a status, the Air National Guard operates under their respective state. The exception to rule is the District of Columbia Air National Guard. Because both state Air National Guard and the Air National Guard of the United States relatively go hand-in-hand, Air National Guard of the United States units or members may be called up for federal active duty in times of Congressionally sanctioned war or national emergency. The United States Air National Guard has about 110,000 men and women in service, even traditional part-time air guardsmen, especially pilots, navigators/combat systems officers, air battle managers and enlisted aircrew, often serve 100 or more man-days annually. As such, the concept of Air National Guard service as representing only one weekend a month, the Georgia Air National Guard and the Kansas Air National Guard previously flew the B-1B Lancer prior to converting to the E-8 Joint STARS and KC-135R Stratotanker, respectively. In addition, the 131st Fighter Wing of the Missouri Air National Guard transitioned from flying the F-15C/D Eagle at St and these proposals were eventually overruled and cancelled by the U. S. Congress. As state militia units, the units in the Air National Guard are not in the normal United States Air Force chain of command and they are under the jurisdiction of the United States National Guard Bureau unless they are federalized by order of the President of the United States. Air National Guard units are trained and equipped by the United States Air Force, the state ANG units, depending on their mission, are operationally gained by a major command of the USAF if federalized. Air National Guard personnel are expected to adhere to the moral and physical standards as their full-time active duty Air Force. The same ranks and insignia of the U. S. Air Force are used by the Air National Guard, the Air National Guard also bestows a number of state awards for local services rendered in a service members home state or equivalent. The creation of the regiments was caused by the perceived need to defend the Bay Colony against American Indians. This organization formed the basis of subsequent colonial and, post-independence, state and this distinction accounts for why there are no National Guard components in the U. S. Navy, U. S. Marine Corps or U. S. Coast Guard

Following a devastating blizzard in 1949, Colorado ANG C-47s dropped hay to stranded and starving livestock throughout the Rocky Mountain region. Altogether the Colorado Air Guardsmen flew 17 such missions dropping tons of hay that saved thousands of cattle and wildlife. Colorado ANG F-51s and A-26s also flew 10 reconnaissance missions during that emergency, 29 January 1949.
