Torn: Initially you can be posted to the Guardhouse of any Reg Force base. Now, having said that, some bases have larger MP Dets than others so the probability of getting somewhere with a small Det, like Wainwright or Meaford, are lower than going to Ottawa, Halifax, Edmonton etc. Once you've completed the Provisional Employment Period, and possibly further training, you are then eligable to be moved to the Security Section (Physical and ADP), Invest, Training etc or be posted to: "Remote" ASU's, like London, Calgary, Sault St Marie, St John's, Chilliwack; a "field" posting to a MP Pl, Cbt Arms unit or a Svc Bn; NIS; NCIU; MSGU; plus a couple others which are unique and interesting...
As for what to do to make yourself more attractive to the Branch...this is a hard one since each MPAC is slightly different. First off, be yourself. Don't try to mould yourself to what you think the recruiter and MPAC personnel want to see. It is very hard to keep up a façade when you are in close and constant contact with people for a week and it will become apparent pretty quickly if you've been doing something because you're actually interested in it, or simply because you were â Å“punching a ticketâ ?. Some things which never hurt if you have the inclination: Community Service/Volunteerism either through your school or outside of it; get involved with sports teams if you aren't already; a â Å“non-aggressiveâ ? martial art, such as Aikido; hobbies can be helpful to round yourself out (drama, believe it or not, would be very useful as it not only teaches you how to act but how to perform in front of others); schooling, schooling, schooling...can't say this enough, particularly writing skills, you're going to write, write, write and then write some more and if you can't put together a coherent report, you might as well not even bother with the work; mental exercises which develop memory and an eye for detail (think the good old â Å“what is different in these two picturesâ ? game), deductive and logical reasoning; getting involved in ride along programmes (hopefully MP, if not check out the local police force); get a job where you actually have to make some decisions (hopefully while under stress, although this is kind of hard to do as a 16 year old); need I mention working on the second official language at this point etc; and most importantly, tell the truth and stay out of trouble!! A criminal record is a sure fire way to not getting past go, as is getting caught in a lie. As for the physical shape you need to be in, the standard for the Branch is the same as for the rest of the CF. It would not hurt, however, if you were also able to do the PARE test in a reasonable amount of time.
Hope this clears the mud a little. Specific questions? Feel free!
