Otto Moritz Walter Model (IPA: [ˈmoːdəl]; 24 January 1891 – 21 April 1945) was a German field marshal during World War II. Although he was a hard-driving, aggressive panzer commander early in the war, Model became best known as a practitioner of defensive warfare. His relative success as commander of the Ninth Army in the battles of 1941–1942 determined his future career path. He has been called the Third Reich's best defensive tactical commander.
