Koch served under Patton in North Africa and Europe as Patton successively commanded I Armored Corps, II Corps, Seventh Army, and Third Army. During the war, Koch developed procedures and policies for gathering and analyzing intelligence and providing recommendations to commanders, many of which continued to be used after the war.
  Following the war, Koch served as deputy commandant and commandant of the Army's first Intelligence school, and as director of intelligence for the Allied occupation of Austria. He was promoted to brigadier general in 1954, and served in the Korean War as assistant division commander and acting commander of the 25th Infantry Division. He retired in September 1954. After retiring, Koch retired to his wife's hometown of Carbondale, Illinois, where he was active in several civic and fraternal organizations. He also authored a brief memoir of his World War II service, which continues to be used as a guide for Military Intelligence professionals. Koch died in Marion, Illinois and was buried at Arlington National Cemetery.
