My unit was once deployed to Cold Lake. Being a collector way back then, I looked up Canadian rank insignia. I spotted an officer and saluted him while most of our folks weren't sure about rank. A MP called me over and thanked me for saluting the officer!
Rank differences. At Cold Lake there was the enlisted mess and the senior NCO's mess. Individual tables with table cloths, A tea pot on the table, dishes instead of mess trays, and a choice ot three entrees! Still have a tea cup and saucer from there. Asked to buy it but they just gave it to me!
I would take a Canadian mess hall over an American one anytime!
