They should build something like this just to show off:There is a documentary on the Soviet Antarctic cruiser Kharkovchanka.
It was developed from the chassis of T-54. The first prototype was developed over just a span of one year (3-6 months even). Preceeding the Kharkovchanka were many tractors developed on the T-32. (T-32-T)
This is China's own tracked winter tractor. Just a sweat-less backyard project for established manufacturing power.
