I don‘t even know the first name of any of my instructors, either on my BMQ, or at my home unit. Only the first name of a few of the members of my section. I refer to everyone by their rank and/or surname.
What a difference from my civilian life. At my regular job, I wouldn‘t dream of calling a supervisor by their last name, not even our terminal managers (I work at customs). Nor would they expect it. Perhaps our regional director, whom I would refer to as "Madam Hebert" or "Ms Hebert".
While on my customs recruit course at our college in Quebec, we had to refer to our program manager as "Mr. Leigh" but every one else was on a first name basis. Part of this is because our instructors were not instructors, they were "facilitators" who assisted us in learning, rather than lecutred us or told us what to do.
This is a sharp contrast to the military! It takes some adjustment, but thankfully all I have to do is look at what colour my uniform is on any day to know how I am to act. Green -> Act like a soldier. Navy blue -> Act like a customs officer.
Great video. My reserve BMQ isn‘t quite the same, and we don‘t get any dress uniform. Our grad parade will be in combats. I doubt our field ex will involve attacking a trench with a pretend bayonet, or climbing over walls...but again, no clue!
