The Vickers Light Dragon was a fully-tracked British field artillery tractor made by Vickers-Armstrongs Ltd from 1929 to 1935. Designed to tow small-calibre field guns, it complemented Vickers' Medium Dragon tractor, which pulled medium to heavy artillery.
There were three main versions, Light Dragon Marks I-III. The first two were based on the chassis of Vickers Light Tanks Marks II and III, and the Light Dragon Mark III used the running gear of the Vickers-Armstrongs DA50, an early version of what became the Universal Carrier.
