How can I end harassing behavior from my Plt Sgt (attempted fraternization)? Is there any specific Army regulation or guidance?

Go above him in the CoC!!!

talk to a Chaplin you will be surprised how they can help make this problem go away

My response would be old school Marine Infantry. You folks have more "difficulties" with the UCMJ now. If the chain of command does not rectify the issue request mast or contact the I.G. Do everything in writing. Things were better when a culprit could be beaten, but equality and the environment now forbid that. I will, however ask why the hell he has your cell phone number? If off post a home# is on the recall list. If in the barracks it's the barracks number. It doesn't add up. The truth is always somewhere in the middle.

Send the messages to the IG (And to his wife) ... that should do it!

He needs a confidante, but his own peer. Id imagine he cant find one.

Hardest thing about GI life is personality conflict. Thats why professionalism is paramount. Good luck.

You have to actually report him to your sharp rep. point blank period.

It's rather obvious he's looking to score--"I'm having relationship problems and I need a shoulder to cry on" is a typical line. Report for sexual harassment. Keep all messages and texts to turn over to the proper authorities.

have you tried Tree-Line Counselling?

If your command is not helping then I suggest notifying the the MP's they will notify CID. Also let JAG know of the situation and that your command does not have your back. His behavior is totally unexceptable, sorry your having these problems.

Your chain of command is not doing anything to fix this problem? Go to the next level and inform CID as well. It should end should the problem reach Battalion level. Best wishes!
