However, the chain of command for Air Force and Space Force units for other purposes than the operational direction goes from the "president" to the "secretary of defense" to the "secretary of the Air Force" to the "commanders of Air Force and Space Force Commands". Air Force and Space Force officers have to report on any matter to the secretary, or the secretary's designate, when requested. The secretary has the authority to detail, prescribe the duties, and to assign Air Force and Space Force service members and civilian employees, and may also change the title of any activity not statutorily designated. The secretary has several responsibilities under the Uniform Code of Military Justice (UCMJ) with respect to Air Force and Space Force service members, including the authority to convene general courts martial and to commute sentences.
