It was to weigh around 30 tons, capable of crossing ditches up to 1.5 metres wide, have armaments including cannon at front and rear as well as several machine-guns, and reach a top speed of at least 12 km/h. The running gear was based on the Holt tractor, parts for which were copied from examples borrowed from the Austrian army. After initial plans were shared with the Army in December 1917, the design was extended to be a universal chassis which could be used as a base for both a tank and unarmoured Überlandwagen ("Over-land vehicle") cargo carriers.
