Felony theft and reserves

What is the name of your state? TEXAS

I have been a reservist for almost 5 years now. In my civilian job I stole items and sold them. I confessed and now possibly facing a felony theft cahrge. Will this get me kicked out of the military? If arrested and / or convicted, how do I go about notifying the military? I had a clean record and a good standing in the reserves. Will any of that help?

Seriously: I would call your commander and let him or her know. Waiting for them to find out by not showing up is inadviseable.

I think this would certainly fall under the general article in the UCMJ. You are responsible for your conduct while on duty and off duty. You SHOULD call your cammander, then speak to Base Legal for further advice.
