Companion to greater opportunity is greater responsibility and for women in the Marine Corps in the 1960s that meant service in the war torn Republic of Vietnam. The announcement was made and plans were set in 1967 for one officer and nine enlisted women to fill desk billets with the Military Assistance Command, Vietnam (MACV), based in Saigon. Generally, they were to work with the Marine Corps Personnel Section on the staff of the Commander, Naval forces, Vietnam. The section provided administrative support to Marines assigned as far north as the Demilitarized Zone (DMZ). Later, another officer billet was added and Lieutenant Colonels Ruth J. O’Holleran and Ruth F. Reinholz eventually served as historians with the Military History Branch, Secretary Joint Staff, MACV.
