Is it possible to get out and come back in through OCS? How would my VA disability claims affect my chances of being approved?

I was prior enlisted active duty Navy, then I switched to the Air Force Reserves while I was in college. After getting my degree I switched to the Army National Guard with OCS in my contract and here I am now. It's not hard to come back in as an OCS candidate. When you speak to a recruiter, tell her you want to come in as an officer and she'll make it happen. They can't make you stay enlisted. To piggy back on what the major said- I'm a weekend warrior, so I don't know if active duty is in need for officers. Junior officers are always in need it seems though. OCS isn't hard, but obviously direct commission is 100% easier bc you skip OCS. But it is very competitive to get a direct commission. OCS isn't easy but it isn't "hard" either. It's like basic training- it sucked but you made it. OCS just requires a little more out of you mentally.

Your VA claim is unique to me though. If you're filing for VA, why are you trying to come back into service? When you file for VA disabilities then (to my understanding), you're officially done with serving in the military simply because of your VA disabilities. Unless your VA disability is something that won't limit your deployability.

What is the rush for a VA disability? If your goal is commissioning, then focus on that and staying healthy to meet the requirements. You are looked at differently when crossing over to the dark side and if I were you, I would go in civies someday to the local recruiter and ask them these questions, keeping your current status on the low to minimize distraction. I also strongly encourage you to explore jobs out there and other branches. Army has the best profile system and alternate PT test events if you are broke, if skinny you practically pass the Air Force test on small abdomen alone. Navy treats their senior personal better than any other branch and knowing what I know about the Navy, I would have commissioned there. Air Force is slim on the kind of nursing I like to do and would have been a horrible decision.
Difficult as coming back, it is needs of the service. I had a poor enlisted record and because of the wars plus my specialty, it was easy for me to return. I am a direct commission and can tell you that you need to be tip top shape for OCS. In my opinion, OCS is the toughest way to commission. I don't think an Officer and a Gentlemen is too far from reality, especially in 1979 when it came out. I would look around for OCS grads and ask them these questions.
