What it is

A light two-man tank with the engine at the rear, the driver at the front and the armament in a fully rotating turret. It set the basic layout of the tank that remains in use.

It is a design milestone, not the first tank (the British Mark I dates from 1916); the FT was the first production tank with its armament in a fully rotating turret (over 3,000 built, most in 1918).

What it led to

  • interwar and Second World War tanks
  • the light infantry tank
  • armoured warfare doctrines
