:sniper: To "Soldier of Fortune" (oh, good grief!):
Members of the Reserve Force are considered civilians while pursuing their civilian lives. They are considered CF members when subject to the Code of Service Discipline.
What this means is that a soldier could (for instance) be charged for being insubordinate while subject to the Code of Service Discipline (see below for the actual circumstances of when the Code applies to Res pers), but could not be charged if he, say, was insubordinate over the phone from his private residence and not currently being paid as a soldier.
It is a grey area in some instances, because the issue of Reserve service liability, Code of Service Discipline applicability, and insurance coverage for Res pers are at times at odds with one another.
For instance: A Res soldier in uniform walking from his residence to his place of duty is subject to the Code of Service Discipline. However; he is not yet ON duty and so it may be argued (especially by the Vet‘s Affairs bean-counters) that, should he get run over, he is not eligible for insurance coverage. There have been several such cases in the last few years where injured Res troops have had to fight their way through the courts to get a settlement. Thoroughly disgusting, admittedly, but a sad fact of bureaucracy.
To Pte F: If that‘s what you were taught in basic trg, your instructors were almost correct. Sadly, a simple perusal of Queen‘s Regulations and Orders would have given them the correct material to pass on. The fol ref should clear it up for you:
