Is it possible to switch branches after being in one branch over 8 years?

I myself have switched to 3 different branches of service. I know many who have done the same thing. Time in service and age can work against you, and certainly the needs of the gaining service is important as well. Then there is your MOS, AFSC, Rate etc that one has to consider and if you want to transfer into the gaining service with a similar job or willing to retrain. Also one has to take into consideration the possible loss of rank and how difficult is it to gain rank in the new career field in the gaining service.

So its possible, lots to consider and your first POC should be a recruiter.

Good luck!

Yes. You need to check the In/Out Calls, as well as read applicable MILPER etc. Not to simplify too much, but as long as you meet the requirements, and your MOS is not understrength, and your desired MOS is not overstrength, then you can reclass.

For 88M, SL2, your MOS is balanced per MILPER 16-117.

Seen it done several times.

Not Uncommon. Plenty of Folks Here. My Dept Head at NSGD Sugar Grove was a Marine before he was a Sailor.

While your best bet is to speak with a recruiter, I have heard that the branches right now are not taking too many OSVETS (Other Service Veterans).

That might, I should think, depend one's levelmof training, as well as how much time one had left in a given svc, as well as the need on thempartmof the gaining svc, I'd expect, you know?

Yes - happens all the time.
