Summer 2014 hires were in CASS/KCM from week one of indoc. I'm surprised to hear new hires must wait until complete with training.
As a mil guy, I can attest that it is a poor decision to take mil leave prior to finishing consolidation. It's a tough transition from mil to 121. Not overwhelming, but not a gentleman's program. Finish training/OE/consolidation, bid around drill, max your $$ by dropping trips only when necessary. My $.02.
