I'm on mil leave as we type. Atlas has been very understanding and accomodating on my activation. I hope to be returning with a few months. However, when I was a drilling reservist, I always bid my days off around drill or drilled and did AFTP's when I had days off. I've never gone on mil leave for drill or AFTP's, so I can't tell you if that works. Maybe someone else can.
I haven't made a decision if I am going to go Retired Reserve or stay on another year-and-a-half as a drilling Reservist. I think I am ready to just have one job to think about and retire from the Reserve. My fun meter is pegged-out. I'm ready to get back to Atlas and enjoy the next 6 1/2 years that I can.
