During the Battle of Merseburg, over half of the Luftwaffe fighters were destroyed by the 8th Air Force, setting a new record.^[13] Fladmark^[14] completed a total of 64 combat missions over Nazi Germany and received the Air Medal with ten Oak Leaf Clusters. After his tour of duty, he was transferred to the United States on January 24, 1945. He was stationed in Santa Ana, California until war's end.

Korean War

Fladmark was recalled into the Air Force on November 14, 1950, for training in jet fighters and a tour in the Korean War. In February 1951, Fladmark^[21] reunited with a flying friend when he was assigned to the 35th Fighter-Interceptor Wing, which was reactivated by Colonel Frederick Gray.^[22] The 35th Fighter-Interceptor Wing was a component of the 5th Air Force, Far East Forces. During the Korean War, he flew 100 combat missions over North Korea.^[23] A report from Headquarters of the 13th Air Force at Clark Air Force Base in the Philippines, reads:

The Distinguished Flying Cross

"Captain Oscar Fladmark, son of Mr. & Mrs. Oscar Fladmark, Sioux Falls, South Dakota and husband of Mrs. Phyllis Fladmark, Sioux Falls, South Dakota, was recently awarded The Distinguished Flying Cross. Assigned as a pilot for the 44th Fighter Squadron (Bomber), Philippines Command (Air Force) and 13th Air Force, Clark Air Force Base, Philippines, Fladmark received the award for exceptionally meritorious service performed on April 24, leading a flight of four F-51 type aircraft on a close support mission, Fladmark displayed airmanship by leading his flight to the target area near Hwachon, Korea, in below marginal weather where the flight carried out a series of devastating attacks on the enemy. With Napalm rockets and machine guns, Fladmark led the flight in pass after pass on the enemy in hazardous mountainous terrain. Only after maximum results had been achieved did Fladmark reassemble his flight and proceed to his home base. Due to the nature of the target and the type of attack it was impossible to ascertain the exact destruction wrought on the enemy by Fladmark but the flight was credited with over 100 Communist troops killed. As a result of this highly successful mission the enemy's drive in the Hwachon area was greatly impeded."^[24]

Post-Korean War

Fladmark, upon his return from the Korean War, was appointed Assistant Professor of Air Science and Tactics for the Reserve Officers Training Corps program at St. Olaf College, Northfield, Minnesota. The Air Force training programs were previous to the establishment of the United States Air Force Academy in Colorado Springs, Colorado. The Air Force subsequently reassigned him to active duty status, and he was stationed with the 85th Fighter Interceptor Group, at Scott Air Force Base in Belleville, Illinois in September, 1951.
