A little idea I had, what if Canada kept the militia instead of turning it into the reserve ?
The militia being a strictly territorial defense force that cant be sent abroad, insuring a ''basic level'' of national coverage if a large part of the army have to be deployed elsewhere.
Recruit: a militiamen in trainning
Militiamen: english speaking militiamen prefer the term ''private'' but this is a colloquial term they use amongst themselves, officialy they hold the rank (and are called) militiamen to differentiate them from the professional private (french speaker dont have this problem since they use ''milicien'' anyway)
Commended militiamen: a ''bastard'' rank between militiamen and corporal, it recognize a militiamen that distinguish itself for exeptional feat either during trainning or during service (or a particuliary senior/veteran militiamen). If use mostly to foster moral and professionalism in the militia, commended militiamen are often the one receiving specialist trainning or leading fireteam duo as they have the right to give order to militiamen.
Corporal: commanding militiamen and commended militiamen in fireteam
Master corporal: a rank given to recognize seniority and prepare the corporal in its duty during their leadership trainning leading to the next rank (mostly due to the longer time needed to transition due to the part-time nature of the militia). Although they are still officialy recognized as corporal, they have authority over other corporal.
Sergeant: non-commissioned officer rank in the militia, command a squad
Adjudant: There is no militia commissioned officer ranks as officer commanding the militia are proffessional officer from the army* but to insure good communication between the militia lower ranks and the officers, the ranks of adjudant is a non-commissioned officer that assist the lieutenant in its task and can command a platoon if the lieutenant is incapacitated or not present.
Master adjudent: like adjudant but assist a captain in running a company
Chief adjudant: last militia rank, similar to adjudant but assist lieutenant colonel in running a regiment
*Each companies shows up for training at the barracks one night a week and do field training one weekend a months. This way, (the staff being kept small compared to regular regiments) officers have responsibilities equivalent to their colleague in permanent units. In case of the entire regiment being called up at once, the small size of the officers' staff would be compensated by way of adjudant receiving increased responsibilities or even gain a substantive rank of Lieutenant for the duration of activation and receive all related advantages during that time.
(Big thanks to
@Marc Pasquin for this idea)
