Should former Marines who join another service give up the Title?

As a sailor and a Corpsman having served with the Marines. I dont think I have ever had this kind of conversation come up before in all my talks with Marines. You earned that title, carry it with all the pride you can muster just like I do as a US Navy veteran and Sailor. Semper Fi by brothers in arms. Doc Gilly.

When your Army you’re Soldier. Once your a Marine your always a Marine who once was a soldier. As a Corpsman who spent 3 yrs with 2nd Mardiv as FMF 8404. I wore USMC uniforms during that time period except the coveted Dress Blues due to regulations but I was always a sailor at heart who could run with the Corp. They called me “Doc” when they were not calling me a pain in the Ass. LOL.

Once a Marine, always a Marine but I'm retired from the Air Force. Proud to be called Marine or Master Sergeant .

Fight it out!
It’s really a non-issue, I had an NCO who was a marine. It’s comical, he was a soldier, and a marine, it’s like you go threw your day while these types questions cross your, stop and think “does this even fucking matter” these men would die and kill for that Title, and with that title comes a loyalty and duty to This Republic, for that I respect these men. So think would they slap your stupid off your face for even proposing the question, with all do respect (put rank hear) shut the fuck up.

Military folks - especially marines - sure do worry and fret a lot over horseshit that does not matter to start with.

Should you give up for wings or tab because you returned to AD in another MOS??? You earned it you keep it.

First off the street No Gourmet Marines!
We earned that title, no matter if you switch to another branch of our military you earned the Title United States Marine.
My opinion.

I went USMC, USA and USAF. My first Army unit called me Jarhead the entire time. I Earned the title Marine. I never earned the title Soldier or Airmen. I just spent time in those branches. I was a Marine.

I left active duty in the 80’s but still consider myself a soldier. I endure where others may not, I carry on my duty to the extent I am able, the mission is still important . My life and worldview were affected and shaped by having been a soldier. I have met many marines who would share the same attitude

I guess my question is, why would a proud Marine join another service? If The Corps means that much to them then why leave it for another service? I am a soldier a proud soldier who led proud soldiers and followed proud soldiers. I served in a proud Army. I am second to none and my Army is second to none. I ETS'ed in 1988, I am still a soldier.
I think the difference between soldiers and Marines is that the Marine Corps train sets man to be more vocal and that's okay, but the Army instills that within soldiers we know who we are.
