I'll try to be brief.
We could run a two-hour seminar on that.
Basically, culture tells people how things should be done. There's a formal culture: the rules, regulations and whatnot, and there's an informal culture. Someone said culture eats policy every time. It's the informal culture that drives what really happens in the organization. The leaders come and they tell you what they'd like to happen. Then you hear from other people what really happens. That's the key—this informal culture. Everyone learns in every organization that's not really the way we do things here.
The difference between the civilian and the military culture is simply the power of the hierarchy and the power that people have. A commanding officer has the legal right to order someone into harm's way. That's the only profession in Canada where they're allowed to do that so it's incredible power.
As Professor Okros said, it's the necessity of working in teams. As Lieutenant-Colonel Eleanor Taylor said, sometimes it is worse being excluded from the team than to tolerate the sexual misconduct, so sometimes that's what people do.
I'll stop there because otherwise I'll go on too long. I hope that helps.
