Previously, and currently outside the program, the Guard was and is subject to a jurisdictional duality: it can be either Federally active or not. If inactive it is a reserve component only of the DoD. Its main function is as a state militia under the command of the Governor through the Adjutant General of the state or equivalent officer of the Territory or D.C. If active, it is entirely out of the jurisdiction of the state and under the DoD, which might or might not keep its original identity, but more likely plunders it for replacements or special units of the Regular Army or Air Force.
