As a French-Canadian, I really have to agree with Slug's assessment, in that we're very tolerable as long as we see you trying, but if you're there, and basically whining every minute about french/frenchies, then no don't expect any help, otherwise, were good people. We usually help out english speakers, because we know where they come from, think about it, Canada is predominently english, over 75% of the geography/provinces work in english, as opposed to Quebec, and some of New Brunswick, so a lot of french people learn english and are in the same situation.
My father moved to Ontario almost 22years ago, back then he knew maybe a handful of english words that had to do with construction and cars, he learned pretty fast, took night classes etc, but people still made fun of him, to this day he's got an accent, and still makes mistakes but you know what he's glad he's bilingual.
About the ISAF doing things in English, well im guessing the people from Canada doing all the talking at that level are officers, and to become a Major and up I believe you have to be bilingual, so that explains that.
Beezer although that may be true, I think the same would be done to a frenchman if he didn't speak/understand english, the fact is if you cannot understand orders. you become a liability, and also if you can't bond with your platoon mates well you kind lose that team unity/bond. I don't think they really had to tell him it was a pre-requisite, its kind of a given, R22eR is a french regiment, same goes for every other regiment in Quebec, they work every day in french, just like PPCLI and RCR work every day in english, you wouldn't feel the need to tell someone that PPCLI do things in English therefore its a pre-requisite to speak and understand english would you, no, because its implied.
It also wouldn't be very reasonable to expect all the unit R22eR in this example to start doing everything in english because they got a handful of english people, and vice versa for PPCLI and others.
