Nothing to laugh about, those snowmobiles.
Very fast, very mobile. Able to insert troops quickly. They were used in the Finnish front from the winter 41-42 forwards and were at times large scale problem, even so that the Air Force bombers flew missions against snowmobile bases. Also patrol aircraft and fighters were used to search and kill the snowmobiles.
You're just showing that you have very little knowlegde about winter fighting by laughing. Winter fighting is not the same as in warm summer or Normandy'44.
