The German Army (German: Heer) was the land forces component of the Wehrmacht, the regular German Armed Forces, from 1935 until it was demobilized and later dissolved in August 1946. The Wehrmacht also included the Kriegsmarine (Navy), the Waffen SS, and the Luftwaffe (Air Force). During World War II, a total of about 18 million soldiers served in the German Army, of whom about 10 million became casualties. Most army personnel were conscripted.Only 17 months after Adolf Hitler announced publicly the rearmament program, the Army reached its projected goal of 36 divisions. During the autumn of 1937, two more corps were formed. In 1938, four additional corps were formed with the inclusion of the five divisions of the Austrian Army after the Anschluss in March. During the period of its expansion by Adolf Hitler, the German Army continued to develop concepts pioneered during World War I, combining ground (Heer) and air (Luftwaffe) assets into combined arms teams. The army used the German term Kampfgruppe which equates to the English 'combat group' or battle group. They were named for their commanding officers using the family name, e.g. Kampfgruppe Meyer. Waffen-SS field formations also served alongside army units.
