What guidance is used in the Army for prior service Marines to wear the 1st or 3rd MARDIV patch?

I spent a few minutes deployed, and I’m fairly familiar with the RIP process. I’d argue that any uptick/downtick in attacks can be correlated to a lot of other things above the wearing of unit patches. But I guess that’s for another thread.

As for the regs. Respectfully, I’d argue that setting a good example for young soldiers, living the Army values (you joined the Army, gotta live by them)..those are better ways to show respect for not only your brothers who didn’t make home but for for everyone else’s, too.
If a prior service Soldier serving in the Corps put unit patch on his uniform, and said, ‘fuck it, respect’, I don’t know if that would fly. Willfully disrespecting the regulations of your service is disrespectful. All of us, alive or dead, are ultimately on the same team. Wearing a patch doesn’t necessarily show honor, and not wearing one doesn’t mean you honor them any less. It just means you wear the uniform according to regulations.

To each his own. When someone approaches me and verbally has a problem with it, we can discuss it then. But as long as I see Soldiers who are wearing a patch for merely being attached to the same unit that I was actually in, a unit that I took pride in being a part of and involved in their deep and rich history, then I’m not taking it off.

By the way, it would be great to see who I’m responding to rather than just Sgt Anonymous.

I guess we’ll agree to disagree. I’d ask though, would not wearing an unauthorized patch somehow indicate you’re no longer prideful of having served in that unit? I’d argue ‘no’.

I’d then ask, as an NCO, where would you draw the line for Privates willifully disregarding any particular regulation? And at what point would their justifications not be acceptable?
I’m not disparaging your friends. But at what point point does ‘tribute to the fallen’ then stop being reasonable rationale for violation of a regulation?

As RP regulations don’t mandate displaying information, I choose not to. I’m no one important. But I stand by what I write.

1) Reinforce an ARMY tradition
2) Draw a reasonable line regarding prior service.
"It is an ARMY rule for SOLDIERS, to protect "bragging rights" of SOLDIERS, not anyone else."

I get all that and per the rule that makes sense. My personal issue isn't that but with the spirit of it. I think it is a bad tradition because we (i.e. Soldiers) shouldn't be looking to brag about anything, nor hold our past experience to create potential bias against others. The only thing that should matter is "US Army" and the rank. This is why I like the Marine model better.

I think this is covered in AFI 36-2903

Being a member of the 49th wing, per the AFI, it simply states identifier tabs and functional badges can be worn, which I do not believe the MARDIV patch falls under. But then again I’m not aware of any reg. That states people who cross train to wear their former AFSC occupational badge. And considering that Airmen are authorIzed to wear Ranger tabs, and Air Assault badges.. I don’t see why this wouldn’t be allowed. I would think the Air Force would want to show how diverse of a branch it is but allowing sister branch service members to show off their former branches
