Vickers Medium Dragon
The Vickers Medium Dragon was a fully-tracked British field artillery tractor made by Vickers (later Vickers-Armstrongs), produced in various versions from 1922 to 1937. It was developed from the carrier version of a 'Tropical Tank' designed by Lt-Colonel Philip Johnson, using components from the running gear of the Vickers Medium Mark I tank. The Mark IV version of the Medium Dragon was effectively a complete re-design, using the running gear from the Vickers 6-ton tank which was not adopted by the British Army. The Army finally decided in 1935 to purchase only wheeled artillery tractors, and no more were sold in the UK, but the Medium Dragon Mark IV sold well in export versions up to 1937. The Medium Dragons towed a wide range of artillery, from 18-pounder field guns to BL 60-pounder heavy field guns.

From c1929 Vickers-Armstrongs also made the Light Dragon tractor for towing light artillery, with a similar name but of a completely different design based on the Vickers Light Tank Mk II.
