What is the probability of switching branches from Army to Air Force?

Real slim unless you have a critical MOS that they need.

I had served in the Army for approximately 12 years then transferred to the Air Force for 6 years and then transferred back to the Army till I had to retire after serving about 6 years.

This is possible (and unique) since this does happen, but a very small percentage of service members do so.

Probabilities? Talk to a University mathematician. If you want to change services, talk to a recruiter - they are the paid experts. If you want random answers listen to the many opinions here before you end up at the recruiters office after all. Are YOU in control of the direction of your career? Or are a group of social media people going to influence the direction of your career? Stop procrastinating and talk to a recruiter and do what is best for YOU (and your country).

Nothing ventured; nothing gain. Good luck!

So there is a good chance. Reach out to a prior service recruiter for the USAF, preferably in your area. There are quotas that they have. Takes about a year if you do it after Army service. If you're still in you can try a lat.

Nowadays?… Maybe more doable on the enlisted side if you don’t care what the AFSC/MOS is . As an Officer ? Slim. Unless you have a STEM skill set or degree , or young enough to be a pilot candidate. The Air Force, Coast Guard and Space Force are some of the most selective branches. And they are not particularly welcoming to prior service members from other branches . I was AD duty USAF, went to Air Guard to finish college and tend to family issues; tried to come back after I got a degree , and it was nothing but run around for 2+ years . So I went and commissioned into the Navy (who were very accommodating). Keep in mind I was already in the ANG & a prior USAF in multiple AFSCs…. I’m just writing this to inform whoever reads , it is very doable to go to Navy/Army from Air Force , but VERY hard the other way around… BUT if it’s what you want , try anyways and who knows what the future holds !

Air Force is notorious for not taking prior enlisted.

Why ate you asking a question here? Talk to a recruiter dummy. Geez.

The question nobody is asking is 'Why do you want to switch? Why did you not enlist in the Air Force in the first place?

is your mos needed? talk to a recruiter
