Tatum enlisted in the U.S. Marine Corps when he was 17. He became a machine gunner and was sent to the newly activated 5th Marine Division at Camp Pendleton, California in 1944. There he became acquainted during training with Medal of Honor recipient, Gunnery Sergeant John Basilone, a machine gun section leader who was killed in action the first day on Iwo Jima and awarded the Navy Cross posthumously. Tatum was sent for further training with the 5th division at Camp Tarawa near Hilo, Hawaii, which was preparing for the assault and capture of Iwo Jima. He was a member of Baker Company, 1st Battalion, 27th Marine Regiment, 5th Marine Division. On February 19, 1945, his battalion disembarked and landed on "Red Beach 2", on the southeast side of Iwo Jima, off of landing boats from the attack transport, USS Hansford, with orders to, "land, seize, and occupy Iwo Jima". Tatum landed with the 1st wave of white faced Marine infantry and their attached Navy medical corpsmen off of LVTs from LST #10 that they had boarded February 11 when the USS Hansford stopped at Saipan. "Red Beach 2", a 550-yard landing zone, was about 800 yards across from Motoyama Airfield #1, which in turn was 1,500 yards north of Mount Suribachi on the south end of Iwo Jima. "Red Beach 2" was one of the seven color named and numbered landing zones that combined were two miles long on the east side of Iwo Jima. Tatum was awarded the Bronze Star Medal with Combat "V" for saving a Marine buddy, Steve Evanson, during fighting at Hill 362 on Iwo Jima. Tatum was subsequently wounded in action and evacuated from the island.
