1st of all, MPs are upholder of military law. therefore must set
good example to all. of course cannot bring camara phones and other
contraband items. how are you suppose people to trust you for
checking their belongings when you yourself are using contraband
items.
at the course, u'll learn about military law, rules of engagement,
basic turn out drills/riot drills, learnt new police firearms etc
etc. plus the usual PT everyday.
after the course u might be posted to learn dog handling or Silent
Precision Drill etc.
