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

If nothing is being done at your company, battalion or brigade level chain of command, go to your division IG

Ig

Just go straight to your company SHARP rep. That don't work go to your battalion SHARP rep and so on.

tell him you have jock itch and ever since the surgery its been unbearable...... "What do you do?"

Report him to your plt. Leader or the first sgt

Request mass if that doesn’t work take it to the chaplain.

SFC (Ret) ... You need to contact your E.O. Or E.E.O rep ASAP!!!! Put your foot down and make him / her do their job!!!! If E.O fails tell the ENTIRE CHAIN OF HIS COMMAND!!!

At your next Bn level SHARP class when the entire COC AND the civilians are present straight up say "my PSG does (fill in the blank). I've reported it to higher but nothing has been done. Is this behavior ok?" LOL, they'll be pissed but it'll be taken care of when people are embarrassed in front of the top brass. Hopefully it's right before their OERs are written up so it's fresh in their memories lol. Or, just make a complaint at the division level, or talk to a JAG officer and see what your options are. Whatever. Good luck.

Go to your SGM.

SPC Ivanov - what Colonel Lenertz and others have said - document it and report it as soon as you can!
