An inside epicyclidal gear allows to drive and made automatically revolving. It looks like Terrastar with Tri-Star wheels but with tracks. See Chapter ’Unusual Locomotion’.

It seems mobility was less good on water covered roads.                  'http://ussrcar.in/wp-content/uploads/2012/04/GAZ69-33.jpg     http://forum.matrasnik.com/index.php?topic=64.20  and  http://www.off-road-drive.ru/archive/3/Prokol__spustila
