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

File and EO complaint! Not sure if the correct name these days because I retired in 2005! His actions are inappropriate and shouldn’t be tolerated. Definitely report it if you feel so strongly about it. Your 1SG and Commander should be informed also. Don’t rely on one source to fix the problem, take any and every avenue to ensure your safety! Be real, make sure you cross all your T’s and dot all your I’s, because if your suspect they will turn this on you and make you out to be the bad guy!

first be shure that it is odd or unusal treatment. i went though marine corp boot camp and i could do nothing right for 4 monthes. if it reaklly is off go to comand or chaplen for help

You should report it to the 1st Sgt.

Fraternization is most definite a no no.. if you have been to your leaders on the platoon level then go up to the company and report him .. and if you really want something done go to the chaplain ... he not their just to pray

Document, maintain, and track all information this Plt Sgt Has given to you about off duty un professional behavior. Make sure you have verbally stated to the Pt Sgt “ I feel uncomfortable with your actions, they are in professional in nature, please stop talking to me about non work related details.” Use your command all the way to the Battalion Commander. Escalate it appropriately. If the command is not resolving the problem. Request Mast, seek an outside command, and involve base legal, Persue the MPs on what steps you can take for your safety both on and off base ( MPs authority stops at the gate), potentially look for a transfer to avoid said individual.

Contact your SARC and report him again. IF you don't have a SARC contact a Chaplain and report him there.

Absolutely do not tolerate it. Save all evidence and inform the next person above him in your chain of command. If you feel like you are being stonewalled in any way go to your battalion sexual assault rep, been a few years can't remember the position name. It's unacceptable behavior. I hope you find resolve

Keep documenting his actions. You can to MP’s and JAG maybe. Good luck.

Sounds tailor made for a chat with your CSM.

Go to the MPs and file a restraining order. Then go to the IG.
