A conceptual arctic crawler version of the legendary WW1 Mark IV Tank featuring wider tracks and a redesigned cockpit. This Crawler is based on the Mark IV Tadpole, which was an attempt to solve the problem of wider trenches dug by the Germans in WW1. The tadpole conversion units were equally compatible with the rear of the Mk V and Mark V*. As an experimental project sometime during 1918 the staff of Central Workshops converted a Mk V* to a tadpole configuration. This produced a tank of over 44 feet long, not only the longest tank completed in World War 1 but also the longest tank ever built.Modeled and rendered in Blender.
