U.S. Marines with November Company, 4th Recruit Training Battalion, sing the song known as “Lady Leatherneck” in the corridors of the 4th Recruit Training Battalion barracks on Marine Corps Recruit Depot Parris Island, S.C., Nov. 8, 2022. The song was taught to the last cycle of solely female recruits and recorded as historical documentation, as Marine Corps recruit training transitions fully to male and female integrated companies in all battalions.
