John Carroll Miller Jr. (December 25, 1912 – July 29, 2000) was a decorated officer in the United States Marine Corps with the rank of Brigadier general.

Miller resigned his reserve commission in order to accept appointment as a second lieutenant in the United States Marine Corps on September 10, 1935.

While in this capacity, he also saw temporary additional duty at the receiving ship, San Francisco, California in connection with Western Division Rifle and Pistol Matches.

[1] With the increasing danger of Japanese expansion in the Pacific during 1939, chairman of Navy's Special Board, Admiral Arthur J. Hepburn, recommended the activation of Marine defense battalions.

Miller was ordered to Johnston Atoll in February 1943 and joined the newly established 16th Defense Battalion under Lieutenant Colonel Richard P. Ross.

[5][1] After a period of heavy fighting on Tarawa in the Gilbert Islands in November 1943, the 8th Marine Regiment under Lieutenant Colonel John H. Griebel needed rest and refit.

[1] Shortly thereafter, Miller was attached as an observer to the Army's 7th Infantry Division under Major General Archibald V. Arnold and participated in combat in the Philippines and Okinawa.

While on Okinawa, he rejoined 5th Marine Regiment on April 4, 1945, when commanding officer of 3rd Battalion, Major John H. Gustafson, was wounded in action and Colonel Griebel needed replacement.

[7][1] Miller assumed temporary command of the battalion and participated in heavy combat in the Awacha pocket, a Japanese stronghold built into a maze of clifflike ridges and tangled gorges.

[1] After a two-month leave, Miller was ordered to the Marine Corps Schools, Quantico, Virginia, where he entered the Command and Staff Course, which he completed in February 1946.

He was ordered to the Panama Canal Zone in July 1950 and served as Executive Officer of the Marine Barracks, 15th Naval District under Rear Admiral Albert M. Bledsoe until February 1951.

His regiment served as a garrison force in Japan and its assigned mission was that of sharing in the defense responsibilities for southern Honshu and of being ready for rapid transfer to potential hot spots in the Far East.

Miller followed him as his Assistant Chief of Staff for Operations and Training and served in this capacity also under Pepper's successor, Lieutenant General William O. Brice.

He served in this capacity during the Lebanon Crisis, a threat of a civil war between Maronite Christians and Muslims and also held additional duty as Senior Marine Officer on the staff of the Commander-in-Chief, U.S.

[1] Following his retirement from the Marine Corps, Miller settled on Oahu, Hawaii and remained there until summer of 2000, when he was ordered to the Naval Hospital, San Diego, California for treatment.
