Yes, you'll be mixed-in with a new-hire class. They start on Tuesdays and finish Fridays.
FWIW, my class was one-third re-hires, and two-thirds newbies. Of them, half mil, and half RJ. One guy from a fractional company, but he had lots of mil-time too (still in the Guard).
I guess I got min guarantee while waiting to go to re-doc; I knew it was 3 a day once actually in training.
