General Roy Stanley Geiger (January 25, 1885–January 23, 1947) was a United States Marine Corps General who, during World War II, became the first Marine to lead an army. Marine Corps base Camp Geiger in North Carolina is named in his honor.

Geiger commanded the III Amphibious Corps in the Battle of Okinawa, where he assumed command of the U.S. Tenth Army upon the combat death of Lt. General Simon Bolivar Buckner, Commanding General of the Tenth Army. Geiger led the Tenth Army until relieved by General Joseph Stilwell.

Following a series of professional examinations and the passing of a Naval Medical Board he accepted his commission as a Second Lieutenant on February 5, 1909.

Further foreign shore duty followed in the Philippines and China with the First Brigade and with the Marine Detachment, American Legation, Peking, China, from 1913 to 1916.

In March 1916, Geiger joined Naval Air Station Pensacola, Florida, as a student naval aviator. He successfully completed the course and was designated a naval aviator in June 1917.

Development of Marine Corps aviation between the wars
From December 1919 to January 1921, he was a squadron commander with the Marine Aviation Force attached to the 1st Provisional Marine Brigade in Haiti. Upon return to the United States and after duty at the Marine Flying Field, Marine Barracks, MCB Quantico, Virginia, he attended Command and General Staff School at Fort Leavenworth, Kansas.

World War II
In August 1941, he became Commanding General, 1st Marine Aircraft Wing, Fleet Marine Force, in which capacity he was found upon the United States' entry into World War II.

On September 3, 1942, he was stationed at Guadalcanal to lead the Cactus Air Force during the early part of the Guadalcanal Campaign. Until November 4, 1942, he was commander of the combined Army, Navy and Marines Air Forces stationed here as well as the 1st Marine Aircraft Wing. He was awarded a Gold Star in lieu of a second Navy Cross for his service on Guadalcanal. His citation reads in part, "Despite almost continuous bombardment by enemy aircraft, hostile naval gunfire and shore based artillery, the combined total of Army, Navy and Marine Corps units stationed at Guadalcanal under Major General Geiger's efficiently coordinated command succeeded in shooting down 268 Japanese planes in aerial combat and inflicting damage on a number estimated to be as great…Sank six enemy vessels, including one heavy cruiser, possibly sank three destroyers and one heavy cruiser, and damaged 18 other ships, including one heavy cruiser and five light cruisers."

He was recalled to Marine Corps Headquarters in May 1943, to become Director of Aviation. In November 1943, he returned to the field, this time as Commanding General of the I Amphibious Corps and led the Corps from November 9, to December 15, 1943, in the Battle of Bougainville, for which he was awarded the Distinguished Service Medal.

Redesignated III Amphibious Corps in April 1944, he led this organization in the invasion and subsequent recapture of Guam during July and August 1944, and in the assault and capture of the southern Palau Islands in September and October of the same year.

Geiger led this Corps into action for the fourth time as part of the Tenth Army in the invasion and capture of Okinawa. On June 18, 1945, Geiger assumed command of the Tenth Army following the death in combat of Lt. General Buckner. To this day, Geiger remains the only Marine officer to ever hold command of a field army.
