It is not enough to "just buy the equipment" required for snow clearance. People have to be trained to use it effectively while minimising disruption to traffic. This requires training and experience.
Between 1991 and 2004 I drove 55K miles a year in the UK and only experienced significant snow about four times and only once was it sufficient to stop me travelling. A lot of this motoring was up to Scotland and, even there, I only experienced snow once.
Unless we send staff to countries who experience a lot of snow, how can we expect them to cope efficiently when we do get snow?
