Can you wear your Marine unit patch as an Army combat patch if you deployed with the Marines? Policy appears to say no.

You were deployed to the MARINES for a time. During that time you wore the unit patch. That was so you wouldn't be considered "foreign" personnel. Meaning you are temporarily attached to the MARINES for a period of time. My brotherand some friends in USAF deployed with the ARMY because of their AFSC (MOS). They wore ARMY unit patches to identify them as being assigned to tthe unit during their deployment. But once they were reassigned back to their parent service, the patches came off. As for permmenate wearing of those patches, more than likely you'll wear the parent service patches only. No use getting the brass bent outta shape, unless you want to.

So, does this mean that if I was in combat with my Navy ship and went back to the Army, I can wear my ships patch as my Army Combat patch?

We did not have these problems when I was deployed. A Huey delivered a pile of fatigues and you grabbed whatever fit. There was no rank or insignia. Two or three weeks later you got another delivery. It was simple.

The answer is NO! The USMC did away with patches in 1947. so you don't have a unit patch.

No such thing as former MARINES. As for wearing a patch for combat, I guess the more stuff the ARMY puts on their uniform the better they feel about being second best.

I had a Plt Sgt who wore a 3rd Marine combat patch from Vietnam

If you were that concerned with wearing a Marine "patch" (still scratching my head on that one). Why did you leave?? Lets dumb this down... You are a former baseball player crying about not being able to wear part of your baseball gear when you joined the NFL. Is that why you serve? To show off your pretty ribbons and bows?

Sir; If you served in a Combat Area as a Marine then turned Army, I see no issue with you parading your Marine DUI on your right shoulder, In my 33 years of service in the ARMY I no of no command who did not allow this , Sir if I were you I would sew it on and to hell with whom ever says different (just my humble opinion)

Regardless of the so called "regulatory " standards, ie; AR 670-1 dash whatever that everyone tries to spout, In all my 33 years of service in the ARMY, I have never experienced an command issue with former Marines being allowed to wear their DUI (1st, 3rd, etc) Marine patch on their right shoulder of the Army uniform to denote COMBAT SERVICE Any Commander who would not accept this honor for ALL Combat Veterans is a fool and not worthy of leading soldiers (My opinion only) Let them have pride in their service as VETERANS no matter the component they served in in combat areas. We are ALL BROTHERS IN ARMS

If that's what keeps you up at night then maybe you shouldn't be a Platoon Leader especially in an Infantry unit. ~ "OUT"
