During the Spanish–American War, members of the Michigan Naval Militia, organized into the Michigan Naval Brigade, constituted the majority of the crew of USS Yosemite.During the war, Yosemite intercepted the Spanish steamer SS Antonio Lopez, beginning the Third Battle of San Juan.[3] The naval militia remained active through World War I, and included a University of Michigan division.Under 10 U.S. Code § 7854, in order to be eligible for access to "vessels, material, armament, equipment, and other facilities of the Navy and the Marine Corps available to the Navy Reserve and the Marine Corps Reserve", at least 95% of members of the naval militia must also be members of the United States Navy Reserve or the United States Marine Corps Reserve.[2] Therefore, the Michigan Legislature has the legal authority to reactivate the naval militia.
