Military career of Adolf Hitler Wikipedia. The military career of Adolf Hitler, dictator of Germany from 1933 to 1945, can be divided into two distinct portions of his life.Mainly, the period during World War I when Hitler served as a Gefreiter (lance corporal) in the Bavarian Army, and the era of World War II when Hitler.
The highest rank he achieved in the German Army was Gerfreiter or the equivalent of a USA Pfc or Private First Class. I’ve heard him ranked as a Lance Corporal but technically he was a “Special Private” one rank.
