Louis Metzger

In July 1943, at age 27, Metzger formed the 1st Armored Amphibian Battalion,[6] and assumed command of the battalion a month later.[3] He led the unit in battles in the Marshall Islands (Battle of Kwajalein), Guam (Battle of Guam), and Japan (Battle of Okinawa). He served as commanding officer of the battalion for 25 months. Military historians largely regard Metzger as one of the primary architects of the Marine Corps' armored vehicle force having led the first Landing Vehicle Tracked (LVT(A)) unit and written most of the armored amphibious doctrine for the vehicle's use in combat.[6][7] He was also awarded the Legion of Merit with Combat "V" for his service during the Battle of Okinawa,[3] where he volunteered to lead in the initial wave of combat on that Japanese island stronghold.[2] In the weeks preceding the amphibious assault on Okinawa, he was promoted to lieutenant colonel.[3]

In August 1945, Metzger was named the Chief of Staff of the Third Fleet Landing Force and was responsible for furnishing Naval forces to occupy Japan. He was given his first Navy Commendation Medal for his role as Chief of Staff. He returned to the 6th Marine Division the following month eventually assuming the role of Operations Officer. In that role, he helped facilitate the surrender and disarmament of the 32nd Japanese Army in Qingdao, China.[3]

After returning home from the Pacific, Metzger spent three years at the Marine Corps' Division of Plans and Policies in Washington, D.C. He followed that by studying a year at the Army Command and General Staff College in Fort Leavenworth, Kansas. Between 1950 and 1953 he served as an instructor and supervisory instructor at the Marine Corps Schools at Quantico.[3]

In June 1953, he became the executive officer of the 1st Marine Division's Kimpo Provisional Regiment during the Korean War. He would later serve as the commanding officer of the 1st Battalion, 1st Marines in Korea. For his service there, he was awarded the Bronze Star Medal.[3]

After returning from Korea, Metzger accepted a role as assistant naval attaché at the U.S. embassy in London, England, where he stayed until June 1956. He was also promoted to colonel in 1955. Upon his return to the United States, Metzger served as branch head at Headquarters Marine Corps and eventually as executive officer of the fiscal division. He graduated from the National War College in 1960 before taking on a role as chief of staff of the 1st Marine Division at Camp Pendleton until May 1962. Subsequently, he served as assistant chief of staff at U.S. Forces Headquarters in Japan and returned to Headquarters Marine Corps in 1964 as assistant deputy chief of staff (programs). He was promoted to brigadier general in 1965.[2][3] In 1966, he became the first director of the Management Analysis Group (MAG) at Headquarters Marine Corps.[8]

Metzger served two tours of duty in the Vietnam War. For his first tour, he was ordered overseas in January 1967 as the commanding general of the 9th Marine Amphibious Brigade. He later served as assistant division commander for the 3rd Marine Division. He was awarded a gold star in lieu of an additional Bronze Star Medal with Combat "V" for operations against enemy combatants that occurred on October 29, 1967.[3] He was promoted to major general in January 1968.[3]

After his first tour, he returned to the Headquarters Marine Corps serving as a deputy chief of staff for three years.[3] Metzger also attended flight school around that time (a notable exception for such a senior officer) to become a helicopter pilot because he wanted to be able to "look his men in the eye and talk to them about their business with first-hand knowledge."[2] In 1971, he returned to the Far East where he served as commanding general of the I Marine Amphibious Force and the Third Marine Division in Okinawa. That year, he was also nominated to the rank of lieutenant general. President Richard Nixon approved the nomination in November and the Senate confirmed it December. He was advanced to three-stars later that month.

In January 1972, he was assigned as the commanding general of the III Marine Amphibious Force. In lieu of a second Distinguished Service Medal, he was awarded a gold star in January 1973. He retired from active duty in February 1973.[3]
