Leave the cadets when it no longer offers you what you want. As you know, the Army Reserves is not CIC, it's a whole different world. It may be best to come in and speak to one of us about training, skills, expectations, career opportunities, etc.
But, the sooner you get into the Reserves, the sooner you move up in rank. My suggestion is for you to get all the phase training done before you attend college/university, that way you are well on your way to becoming a senior NCO or Officer.
If you're are 16+, on paper you are good-to-go for the reserves.
You should come in for a Wed night info session at 1930 Hrs. Since it's summer stand-down, and I'm away until Stalwart Guardian, you may want to go into the unit during the day and talk to the recruiting NCO. He'll be more than happy to talk to you about the regiment.
Or, call 905-541-ARMY and schedule yourself an appointment.
