This is a Piston Bully. This was like a game-boy to drive in the snow. The small half steering wheel sits in your lap and the throttle is a small ball you spin with your thumb. It is so responsive that you have to be careful not to spin it in a 360 in one spot, unless that's what you want.
The hagglunds are affectionately called haggas's and are noisy and unless you have some padding or a cushion you don't want to go far in one. I enjoy driving them as they are basically a simple automatic. They are completely sealed so that if your were to fall through the ice they float, and they have marine escape hatches in the roof - do not open doors if you fall through the ice. The steel tracks on the roof are for going over crevasses, something that will not happen I'm sure.
