If you have, it is a very rare sight. They may have been former Cbt Arms, now MSE Ops, who may have had to move a vehicle a very short distance. Other than Cbt Arms and Mechanics, you are not likely to see anyone else drive a LAV. You may find Sigs and Medics qualified on Bisons, but again, it is usually Cbt Arms people. It is very unlikely that you will find a MSE Op driving an Armd Veh Tactically or Administratively on any Exercise or Deployment. When it comes to Tracked vehicles, it is the Cbt Arms (Armour, Inf, Arty, and Engrs) who will be driving them. In most cases, on a Base, it is the Engineers who operate most of the Heavy Equipment. MSE Ops will operate various pieces of Airfield Heavy cranes, etc. and wheeled Heavy Equipment like Graders and Forklifts, in certain locations.
