It’s easy to sleep on reserves or NGs because they’re not necessarily full timers. But some are. With a big résumé behind them. Some deploy with more experience than active units. Some have no active equivalent
It's always changing. Best to chat with the unit/recruiter. Sometimes you could contract straight through as long as your ASFAB scores were there. Other times SF would want you to go to another unit and come back when you were an E5 or 1st Lt promotable....
