I had the chance to write a tech report for Mapping and Charting Establishment (the military's survey, mapping and terrain analysis unit) after a wolf chewed on some GPS survey equipment in the high arctic. No one was hurt, just surprised. The men were unarmed. The SOP should have been to request some 12ga slug shotguns but that didn't happen on time. I took it upon myself to challenge that idea for the future.
There are 8 or 9 animals in Canada that will hunt and kill, or aggressively attack humans - polar bears, grizzly bears, black bears, bison, cougars (er, mountain lions not 'mount and lyin's'), bison, moose and bulls. Survey crews frequently work in isolated areas, and have to stay on station for long periods.
The recommendations was the military issue survival rifle (yes there is one!, a .303 like the EAL), loaded with heavy soft point bullets, available through the system or commercial with approval of the item manager. It would be sufficiently powerful and simple enough to train and use.
Alas, the DCO didn't think it was necessary and the security arrangements for a bunch of bolt action rifles would have been surprisingly complicated.
