How to address hate and gang associations in the military?

This is interesting. Has there been a ruling on whether or not military tattoo policy is unconstitutional?
There is an interesting article here, starting on page 56: https://www.loc.gov/law/mlr/Military_Law_Review/275085~1.pdf

Anecdotally, I went to boot camp with a guy who had to get a drug tattoo covered up before he could join.

Capt Gregory Prickett I wonder how that works with AF regulations as some freedoms can be curtailed? A1C Chris Pointer Gave us the regulations:

3.4.2
"Tattoos/brands/body markings anywhere on the body that are obscene, commonly associated with gangs, extremist, and/or supremacist organizations, or that advocate sexual, racial, ethnic, or religious discrimination are prohibited in and out of uniform. "

3.4.1.1
"Members who have or receive unauthorized content tattoos/brands/body markings
are required to initiate tattoo/brand/body marking removal/alteration."

I also noticed that the date of the regulation was 20 Jan 2020. I don't know if any of that verbiage appeared before that and question if perhaps there might be some grandfathering in play?

SPC Kevin Ford - Those regulations are for the good order and discipline of the service, and can be valid from a uniform appearance basis only. He's still got free speech and association rights.

It's ultimately the commander's discretion: "membership in a white nationalist group "is not prohibited," but "active participation" in the group could lead to an administrative discharge, at a commander's discretion."
