Well, i'm a MP myself(NSF)....it doesnt matter whether u wear glasses or not....and yes,MP is a combat vocation and u'll get combat pay.well, I'm not sure about the Regular's pay. It should be the same as other combat units.During my BMT,i was selected for the MP interview and they will choose according to your height.Regarding training, After your BMT(of course you ahve to go thru BMT!) you will have to go thru a MP basic course abt 3 months,and if u're coming from SISPEC, you will have to go thru a SPEC 2 course(3 months). During this course, you will learn military law,Unarm combat,roles of the military police(how to arrest people....Things that MPs do...),basic drills,FIBUA, how to handle a P226 pistol...After that ,you will have to go thru a 3 D 2 N summary exercise. After that u will get your posting. There are 5 coy...they are Zone provost(Law enforcement), Active provost(drills,drills and silent precision drills,parades,SAF day and NDP), Special Investigation Branch ,Security branch and Dog unit. If u kenna external posting, it'll be doing guard duty at mindef or being the guard commander there. If u sign on as a regular, you will go thru your tour, which means that u will have a chance to be posted around the companies in Provost.About the interview that u mention, i dont really know what are the questions. just be confident and show your interest and desire in becoming a MP. If you kenna my company after the MP basic course, you will be doing drills,drills,parades,parades....ironing of uniform....silent precision drills.(difficult to master)..
