I am currently in the National Guard and I ETS soon. Is there a way to transfer to active duty, or is it just easier to finish and reenlist?

Rgr, just go to a regular recruiter and let them know your situation. They should be able to have you enlist the day after your ETS so you don't have a break in service.

Not sure anymore but I was a reservist and due to ETS but wanted to go active. I just had to talk to recruiter to get a new contract. Was easy peasy brother

Most likely, it'll be easier just to ETS --depending on how far out your ETS that is and how fast your CoC actions these things. I mean, it doesnt hurt to request a Conditional Release since the worst they can say is no, in which case you'd ETS anyway. Best case, youd get approved and can leave a bit sooner. Either way you must first talk to a recruiter. Good luck with your transition !
