We used these regularly. Especially when we deployed to Chilcotin (BC) for winter ex, where without them the tracks just would just spin. They worked well in snow and icy conditions but with the limited weight of the vehicle and their fairly large surface area they would not punch through really thick ice and you'd be skating rather than sliding, but we're comfortable on skates in Canada!

They were used sporadically in Wainwright and Suffield it just depended on conditions that particular winter. The open plains of Alberta never got enough snow to make them absolutely necessary but we used them every time in BC. I can remember the SSM going up one side and down the other of a driver that forgot that "one" grouser when we drove on the highway to the railhead. Little "X's" all along the highway, a trail to follow.
