Mark V

In service 1918 - 1920s

The most refined WW1 rhomboid: one driver, epicyclic gearbox, purpose-built engine.

Built byMetropolitan Carriage, Wagon and Finance Co.

Development history

Where earlier marks needed four men to steer, the Mark V's Wilson epicyclic gearbox let a single driver control the vehicle. A purpose-designed Ricardo engine and better ventilation made it far more usable. The stretched Mark V* added a hull section to cross the wide Hindenburg Line trenches; survivors served with several armies into the 1920s and 1930s.
