I need confirmation on the following statement, please.
As far as I understand, upon successful completion of DEPOT, a reservist will graduate as an E3 and report to his drilling unit. She/he will stay as a non-rated E3 until attending A-School. Whether A-School is right after DEPOT or 2 months or 10 months after, she/he will become a rated E4 once graduated from A-School. The only exception to this situation is if this person is prior military. In this case, she/he can graduate from DEPOT as an E4.
(If this is correct, then my contradiction is how come one doesnt become a petty officer by completing a petty officer training course.)
Thanks in advance
