I got chaptered out for APFT failure back in 2018. I currently receive VA disability, but is there anyway that I could join AD again?

In addition to what has already been said, you understand that the new fitness test is even harder?

I'm going to guess you failed on the run, because that seems to be the most common failure. The run is even harder now because of all the events preceding it take a toll.

Not trying to discourage you, just giving a reality test.

The new ACFT is well documented now on Social media. Learn about it, conduct a self assessment, and if you still feel that you can hack it, go see a recruiter and give it a go. Just don't go in with high expectations

You were separated because you could not maintain an Army requirement and now you are disable, How do you expect to overcome these hurdles?

If that was a resume. It would not be a good one.
