Medium Mark D was a British medium tank developed at the end of the First World War.
It was envisaged as a vehicle to be used in "Plan 1919" an offensive on the Western Front which would use large numbers of heavy and medium tanks to break through the German defences, destroy lines of communication crippling the German army and thus end the war. The Armistice ended the war in 1918 and it would never be tested in combat but development continued for the post-war needs of the British Army. The unusual suspension proved problematic and the earlier tanks were replaced by a Vickers design - the Medium Mark I - in the 1920s[1]
It should not be confused with export Vickers Medium Mark D tank, built in one unit for Ireland in 1929.
