At the end of World War 1, the German war machine was dismantled - losing its power to manufacture aircraft, tanks, submarines and most other instruments of war. Throughout the 1920s and into the 1930s, there grew a new movement which felt the humiliation wrought onto the German nation by the victors of the conflict. The movement soon encompassed all of German life and allowed leader Adolf Hitler to assume control of the economically depressed populace. The war machine soon grew outside of the limitations of the Versailles Treaty imposed upon the Germans following World War 2. Tanks were being produced under the guise of farming tractors while the burgeoning German air force -the Luftwaffe - was secretly training its pilots on gliders. With the arrival of the Spanish Civil War, all was fair game and the German war machine received its first taste of real combat on all-new developments - Panzers, Messerschmitt, Stukas - all played a major role in developing the German doctrine of "Lightning War", an overwhelming military thrust using coordinated assaults from land and air.
However, as the German military might grew the reach of the German military was surely to be tested. Considering the aspirations that Hitler maintained for his conquest of Europe - beginning with Poland and ending with the United Kingdom and Soviet Union - the problem was going to be a sound logistical force capable of bringing men, weapons and supplies from one point to another. By the late 1930s, the German military inventory boasted a plethora of such "mover" vehicles but there was not the universal solution as required of war. The task of consolidation would fall to General von Schell who proceeded to deliver an ambitious plan to bring the number of German military logistical vehicles to a quarter of the original offering, each solution categorized by role and weight class.
