The installation commander determines when, where, and how to implement random checks of vehicles or pedestrians. The commander conducts random checks to protect the security of the command or to protect government property.

(a) Air Force installation commanders are responsible for protecting personnel and property under their jurisdiction and for maintaining order on installations, to ensure the uninterrupted and successful accomplishment of the Air Force mission.

(b) Each commander is authorized to grant or deny access to their installations, and to exclude or remove persons whose presence is unauthorized. In excluding or removing persons from the installation, the installation commander must not act in an arbitrary or capricious manner. Their action must be reasonable in relation to their responsibility to protect and to preserve order on the installation and to safeguard persons and property thereon. As far as practicable, they should prescribe by regulation the rules and conditions governing access to their installation.

Under Section 21 of the Internal Security Act of 1950 (50 U.S.C. 797), any directive issued by the commander of a military installation or facility, which includes the parameters for authorized entry to or exit from a military installation, is legally enforceable against all persons whether or not those persons are subject to the Uniformed Code of Military Justice (UCMJ). Military personnel who reenter an installation after having been properly ordered not to do so may be apprehended. Civilian violators may be detained and either escorted off the installation or turned over to proper civilian authorities. Civilian violators may be prosecuted under 18 U.S.C. 1382.

Commanders are prohibited from authorizing demonstrations for partisan political purposes. Demonstrations on any Air Force installation for other than political purposes may only occur with the prior approval of the installation commander. Demonstrations that could result in interference with, or prevention of, the orderly accomplishment of the mission of an installation or that present a clear danger to loyalty, discipline or morale of members of the Armed Forces will not be approved.

Under the authority of 50 U.S.C. 797, installation commanders may deny access to the installation through the use of a barment order. Barment orders should be in writing but may also be oral. Security forces maintain a list of personnel barred from the installation.
