The poster who said because you are young ... has it nailed.
For example:
Right now there are 70 candidates on the Raven Aboriginal Youth Employment Program. Of the 70, less than a dozen are over 19. The average age is 17. They are enrolled in the CF (with parental consent) Reserve for the duration of the course. They are doing BMQ. They are issued a C-7, they will do field training ... just as any reserve recruit. Other than the weapons training and the field work the course is comparable to the Cadet Leader Instructor Course ... map and compass, navigation, first aid, survival, basic military knowledge (ranks etc.), drill, dress, barrack husbandry ... you know the stuff.
Without knowing the nuance of their official circumstance it defies any reasonable person to tell which children are the Raven Company and which are the cadet company. The Ravens are wearing Cadpat the cadets are wearing OD. The Ravens have C-7s. The Cadets have DP Enfields.
It is just the way it is ... PRes personnel 16 to 18 are children enrolled in the CF. Cadets aged 12 to 18 are children in a youth program. Without knowing ... there is no way to know.
