Can i drive my POV to AIT as a prior service going actuve duty Army?

Im in a similar situation. As prior service, everything dealing with your transportation, including whether you can drive your car to the location, is done at MEPS. When I did it, the MEPS liaison asked me if I wanted to fly or did I want to drive my POV.

The bottom line, you'll need to get your request to the MEPS liaison that processed you into the army to see they can change your transportation method. Ask your recruiter if they can submit a request to change your orders. If that doesn't work, I would try to send them an email on global. You should be able to find their name on the paperwork given to you at MEPS.

Of course, if the job course or installation has some rule against it, you can't do it. For that, I would say give them a call and ask them directly.

You can, but MEPS is responsible for shipping you.
If MEPS says no, then no.

Depending on the length of your AIT and Ft. Sill policy. You need to contact the training Command at Fort Sill.
