Canadians have to be the most intense Nazi hunters on the planet, every pic I see they have their poop together. In that pic you got a spotter with a tommy gun and a guy laying there ready to wipe out a group of Nazis and another guy with the LE watching their 6. I would run from them too if word got out Canadians are coming.
The Lance Corporal with the Thompson will be the section commander. The kneeling soldier isn't "watching their 6"; he is looking in the same direction as the others. Could well be the No. 2 on the Bren. Much of the time in Italy, Canadians were opposed by German paratroopers. They didn't tend to run.
