Rule 61. If the president calls or orders all or part of the national guard into federal service in time of a national emergency, or if it appears that the national guard may be called into federal service, the governor, as commander-in-chief, may organize within the state military establishment such number of army and air force units as he deems necessary for the adequate protection of the state. These units, known as the Michigan defense force, shall protect the state in case of insurrection, invasion, disaster, or other emergency, actual or imminent. The Michigan defense force shall be governed by rules and regulations similar to those governing the national guard.
