Can a soldier's wife be banned from coming on post?

She is lucky she wasn't charged with anything from the local provost marshal... also she derserves to be banned

Sounds like enough reason to ban her to me....,.

My husband went AWOL for three years after his tour of Bosnia. He turned hisself in, was barely punished and deployed with his unit shortly after. Why you ask? Because my husband was a trained CAV scout sniper, a badass. He's now medically retired after losing his leg on his second tour of Iraq. Now he's 100% VA with CRSC.

It happens all the time. I’ve seen several spouses banned from base. It usually involves criminal activities.

So the wife’s hubby I would think would be in equal trouble for sheltering an awol soldier. Harboring a fugitive is a felony in the civilian world, if the UCMJ looks at it like that he could be out , dishonorable, loss of benefits, fine or jail. Maybe he needs to find a new wife, life’s too short to deal with that crap, send her ass back to mommy.

Anyone can essentially be banned from an installation (obviously not currently serving military.) I'd say only that last reason would be a possible reason to. If someone is becoming a constant nuisance (more than just spouse drama) and constantly disrupting good order and discipline on the installation then it's a logical reason for them to be banned. Ultimately legal and I'd say probably the GC would be the ultimate decision maker on banning someone.

Yes

Oh yeah. And if it is overseas they can be sent home.

The short answer... Yes.
The long answer.... Yes they can for various reasons as deemed necessary by the installation commander or appropriate authority.

Yes. By the garrison commander.
