A17 Light Tank Mk VII Tetrarch I

Tetrarch I

Front view of Tetrarch at Bovington, 1998

The Light Tank Mk VII Tetrarch was originally intended by Vickers in 1937 as a successor to Light Tank Mk VI, but was not at first accepted for service in this role. Tetrarch was, however, taken into British service in 1941, and was used in the invasion of Madagascar. Tetrarchs were also supplied to Russia. They are perhaps best known for their airborne use as the freight of Hamilcar gliders. Tetrarch remained in British service until well after the war (~1949).
