Stuck in between a rock and a hard place for Halloween.

Wear the uniform of a different branch.

I have done it once after i got out.
Mind you only once. The neighborhood was not military friendly and even though i had removed all patches from the BDU (yes it was that long ago) I had to bite my tongue, smile and remember I am out there with my children and this was a day for them.

As an NCO you are there to set the standard for soldiers under you. It is highly distasteful as an NCO to wear your uniform as a Halloween Costume. Why would you want to bring that attention to yourself and disrespect what so many have sacrificed while wearing the uniform? If it's during duty hours, and you have work/appointments that would take you outside the Company AO, then I would understand why you would wear your uniform.

Wrong

I would wear it with nothing on it. Just to play it safe

You are dressed as Soldier....

Wow,the military is getting laid back with allowing a Halloween costume, is it a drill function?
I would just check with your senior NCO, or CO on uniform concerned to cya.

Don't be ridiculous the uniform isn't a Halloween costume. Put a grocery sack over your head or something
