Is it possible for me to commission into the Army (through ROTC) then get a conditional release to be an Air Force Officer?

It's technically possible, but highly unlikely to ever occur. That's a workaround to try to find a back door into the AF.

If you really want to be an AF officer, I would recommend pursuing AF ROTC. Otherwise, if you are looking at pursuing a commission through Army ROTC, you will need to accept that you may very well have to stick with an Army career.

Possible yes. Probable no. There is a form for it. When you commission you can technically change your Army branch but it is highly unlikely (I am sample size of one). There is another form for that. The only time I have heard this happening is with Service Academy Graduates. I served with an Armor Officer that was a USAFA grad.

Intraservice transfers in concept work like this: the gaining service has to accept you. The Army then has to release you. Sounds deceptively simple. If you are accessed into a shortage field then you will not get released until your branch deems that your year group is over strength, and then maybe not. I had a fellow cavalryman that was branched infantry. He tried year on year without success to transfer to aviation. He finally got accepted into a naval aviation program to fly Sea Stallions. That languished for months. He finally had to take leave, fly to HRC in DC, found the staff officer that was sitting on it and confronted him directly. To the Colonels credit, he asked one question do you really want to be a Naval Officer. Bob told him yes, and he endorsed the transfer paperwork and walked him place to place and had it approved by the end of the week. A few weeks later he was watching Top Gun trying to figure out how to put his crap on his khakis....there is no transition course.

There would have to be something significant for justification to make it happen.

What I don't know is if you tried floating between the Army National Guard and the Air Guard.

Also, I'd been Army ROTC 3 yrs, on scholarship the latter 2 yrs, I wasn't able to finish, I went USAF OTS afterward, when it'd been at Lackland, before it was moved to Maxwell, where it is now....

Why would you try to be an army officer if you want to be an air force officer?

I don't think it works that way, first off you signed a contract with the Army and you have to be released out of that contract which rarely happens. If your in the Army then your obligated but you can always check with JAG and ask about the regulation but you did sign a contract.

If you want to get into the AF what I would try and do is apply for an Acceptation to Policy and check into the Space Force. It's a small chance but a very good one.

What, possible yes, probably Never! Why should the Army pump money into your education and training and then just give it to the USAF? Change to the USAF ROTC and stop waffling.

I'm not sure if this still happens, but used to be even if you went to a service academy, you could commission in another service. Looks as if ROTC would be similar.

And all commissioned and warrant can apply to go to AFIT and NPS, AFIT also lets senior USAF and Army NCOs go there to finish their PhD, I've seen YouTube videos on that program for senior NCOs, as well...NPS, I don't know, however, AFIT, definitely....

I had an O-6 recommend from my CO to go here, I couldn't get it, I suggest both NPS and AFIT, as well as USUHS for you (not USPHS, that's the other service I'd mentioned, USUHS is a school, of course, as I'd said), because the moment you go commissioned, all commissioned and warrants are expected, trust me, been there, done that (BTDT), to get to at least masters level, even if needing to go part time, the days when a bachelors would suffice to stay in are, I assure you, at least from my personal exposure, long, long gone...plus, you'll most definitely find you'll need the added training, that much I can most definitely promise you, aside from needing to do your professional mil educ (PME) coursework, USAF was SERIOUS about wanting it done FAST, as in ASAP, from the very day you commission, that much I can most definitely promise you, I'd expect Army wouldn't be any different, honest...just food for thought, OK? As I'd said, if you'd care to elaborate and/or chat more, just ask, I'd be most interested, I'll try to suggest more as well if you like....
