I am transferring to reg force when I finish my degree next year. Will the men treat me a bit better because I have a little experience, and I will be joining at the age of 31 so is it still possible for me to ever become a LTCOL or higher?
Blackberry: First, stop worrying about what rank you will get to and focus on being a good officer.
Second, heed the words of Infanteer:
Respect is something you will have to earn through competence and good leadership; although someones background may put them in a better light, it shouldn't give them the automatic respect of others.
There is nothing harder to win, nor easier to lose, than the respect of the Canadian soldier. You will only ever earn it: you can never demand it. Those fools who beak off about "demanding respect" will at best get grudging obedience. Obedience can be mandated: respect cannot, nor can loyalty.
My story is similar to yours. After eight years as a Reserve Infantry soldier, I achieved the rank of WO. I did not like officers very much, and many of them did not particularly like me. In fact, I was proposed for commissioning in my unit twice, and twice turned down, the second time with the comment (anecdotally) "He will always be an NCO..." I reached a point in my life at which I needed to make a career decision, so I decided to go Regular, because I enjoyed military life. I was going to go in the NCM route, but a PPCLI MWO convinced me to try the officer route instead. So I did, at age 24. (I was a good 4-5 years older than my peers in officer trg)
I found BOTC relatively easy (except for the PT and rucking up the mountains: like most Res soldiers I was not fit...). I found the Inf School started out easy, but got harder as the training moved beyond my experience base. However, I am quite sure that my Res experience helped me get through those two schools. As I commented on another thread, those with Res experience who go through RegF DP1 should IMHO keep their mouths shut, work hard, and help their less knowledgeable "civvy" buddies. Don't beak off about your Res time. If you know it, show it.
After those DP1 schools were over, I found that while my background helped me greatly in dealing with WOs/NCOs and soldiers, it did me little good on the various officer courses I began to go on: I had to start from scratch.
My advice for a person of your age is to be prepared to train alongside, and be trained by, people younger than you. As well, at your age, you will probably need to make an extra effort to prepare yourself physically.(Unless of course you are already a fit person, in which case keep it up).
Good luck. I can honestly say that after 30 years I regret verly little about my decision. Cheers.
