Mich. Comp. Laws § 32.736
The armories, air bases and naval installations erected, constructed and owned by the state, leased by the state or provided by the federal government by either lease, license or use permit, shall be for the use and benefit of the organized militia quartered therein. Organizations of the Spanish-American war veterans, veterans of foreign wars, the American legion and other war veterans' organizations, upon their written request to the adjutant general may be granted the use of state armories, subject to the rules governing the organized militia quartered therein and regulations of the military establishment. The use of such armories free of charge for all veterans' district or state conventions is authorized. The use by the organized militia or other military organizations of intoxicating liquors in the armories, air bases and naval installations of the military establishment is authorized. The adjutant general shall publish directives to insure proper control of such use and any officer or enlisted man guilty of violating these directives shall be punished as a court martial shall direct. With the approval of the legislative body of the political subdivision in which an armory, air base or naval installation is located, outside parties of a nonmilitary or state governmental nature may use or serve intoxicating liquors in conformity with rules and regulations of the liquor control commission, if not in violation of any other local ordinance, state or federal law or regulation.
