No, a Sicard was (is?) a sort of rotary snow redistribution jobber. And if I recall correctly, there's also another snowy-chewy-uppy-thing called a 'Rollba', I think?
We had quite a lot of snow one winter at a certain large AT/AAR base in British West Oxfordshire. The Blacktop chaps did an excellent job in keeping the runway open, so then it was time to clear the main drag through the station. Along comes the duty bowser-with-blade and off it chugs. Minutes later there is an almighty BANG and the bowser comes to a halt with bits of broken ironmongery poking out of the front and the blade sitting on the road looking rather sadly bent.
It seems that a certain, not terribly popular, Stn Cdr had insisted that speed bumps had to be laid on the road to stop people speeding...
Which, though a bŁoody nuisance, could normally be seen quite easily - except when they were covered in snow...
. They were certainly made of rather sterner stuff than the bowser-plough...
