General Roy Stanley Geiger, who commanded both air and ground units during World War II, and was the first Marine to lead an Army, died 23 January 1947 at the National Naval Medical Center, Bethesda, Maryland, and was buried in Arlington Cemetery.

General Geiger commanded the III Amphibious Corps in the battle for Okinawa where upon the death in action of Lieutenant General Simon Bolivar Buckner, Commanding General of the Tenth Army, General Geiger assumed command and led the Tenth Army to the successful conclusion of World War II's final campaign.

For his part in this action he was awarded the Distinguished Service Medal (Army). His citation reads in part, "Going ashore with the early landing elements on 1 April 1945, he began a bitter three-month campaign…with outstanding professional skill, forceful leadership and unswerving determination, he directed his units…repeatedly disregarding personal safety to secure a first hand estimate of the battle situation and inspiring his men to heights of bravery and accomplishment."

General Geiger was born on 25 January 1885, in Middleburg, Florida. He attended Florida State Normal and received an LLB from Stetson University, following which he enlisted in the Marine Corps on 2 November 1907. He was commissioned a Second Lieutenant on 5 February 1909.

Following attendance at the Marine Officers' School at Port Royal, South Carolina, he served as a member of the Marine Detachments aboard the USS Wisconsin and the USS Delaware.

He led the 1st Marine Aircraft Wing from 3 September to 4 November 1942, while stationed at Guadalcanal. For extraordinary heroism in this capacity as well as commander of all aircraft, he was awarded a Gold Star in lieu of a second Navy Cross. 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 Headquarters Marine Corps 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 9 November to 15 December 1943, in the Bouganville Operation, for which he was awarded the Distinguished Service Medal.
