Service members and civilians aboard Marine Corps Air Station Cherry Point watch a video commemorating the Montford Point Marines, the first blacks allowed into the Marine Corps, during a ceremony at the Marine Corps Air Station Cherry Point Theater, Friday. Until 1942, the Marine Corps practiced a discriminatory policy, not allowing African Americans into their ranks, making them the last of all the military branches to finally do so. The policy wasn’t changed until more than two decades after they began allowing women to join their elite ranks.
