Well, I just want to point out that, even in recruiting, personnel have different personalities. Apparently, you are seeking position as an Officer and the lad next to you as an other rank ... two whole different ball-games; trying to compare the two is silly. And, the native Canadian in the booth next to you was being seen by a different person with a different personality than your particular staff. Some people have great personalities, others no so much. Please don't over analyze the situation while forgetting the basics of human interaction. The mountain of which you post is more than likely just a molehill.
As for the answer to your question to the recruiter about "who deploys the most", it is entirely unpredictable. It is totally dependent upon what missions our government chooses to send us to as participants. I still haven't met an individual who can accurately predict what those folks are thinking. A UN mission could see an "all-Loggie" task force with very minimal zero trade involvement by Canada such as we experienced during our decades in the Golan Heights. We could see a Naval Task Force, such as recently occured in Libya. We could see another mission that closely involves our front-line personnel and their support staff such as Afghanistan.
Your list below is entirely inaccurate as who is tasked to deploy is entirely dependent upon numerous things: mission requirements, tasks, goals, HQs requiring staff, type of mission.
If you are hoping to avoid deployment, or to minimize that, I'd suggest that you seriously consider whether or not the CF is actually for you. Unfortunately, it is what we do and we can't predict where, when, or who our Nation is going to call upon ... or how often that will occur. It's part of the business and that uncertainty is exactly why the CF is considered a lifestyle vice a job. If that uncertainty and unpredictability is
really not OK with you, then really consider the consequences of siging on that line.
