Can leadership threaten a soldier not to talk to another soldier with UCMJ?

PFC (Join to see) - I think the verbal order is when your squad leader and 1SG say, "You cannot have contact with this individual. If you do, you will receive UCMJ action."

PFC (Join to see) - I understand the sentiment from your statement. As a leader, I would certainly counsel you (on paper) about my expectations before trying to threaten you with punitive action. However, I would take someone saying that conducting X action result in punishment would constitute a verbal order not to do X action. I wouldn't try to barracks lawyer the semantics of it. That said, I've never specifically read the minimum rank for issuing authority for a no-contact order, and soldiers are supposed to be given a say. Especially because this is the second time there has been an issue, your chain of command should have enacted other alternatives to prevent issues and maintain the safety of their soldiers. If you disagree with the order, talk to the JAG for advice and recommendations. I wouldn't try to take your case the commander based on advice you get from Rally Point, no matter how accurate it may or may not be. Or worse yet, just continue to have contact and try to claim ignorance of the consequences later.

The two soldiers once had a no contact order but it was lifted and they were told they're not meant to be together as a couple. Then later another one was put in place for a time but was dropped after a month had passed.

Now her squad leader is threatening to write her up if she talks to him but no verbal order was given and the 1SG is threatening her with an Article 15 for just talking to him again no verbal order was given.

This does sound shaky at best.

The chain of command is just wanting to avoid problems. Obviously if they had a prior non contact order, there might have been some type of domestic issue going on. Chain of command is taking preventive measures.
