A Marine is a Marine for life! He is a Marine from the yellow foot prints in Boot Camp, till the day of his death and beyond. Even after death, "once a Marine Always a Marine". It is considered rude and impolite to call a Marine and Ex-Marine. He can be referred as an Inactive or Retired Marine.

Joe: That Tom is still hard core! Didn't he get out, like, two years ago?

Sam: Yeah, He is an out going Ex-Marine!

(Tom apears from no where in a puff of smoke,and slaps the hell out of sam and states loudly ("Semer Fi For Life").

Something that doesn't exist. You stop being in the Marines; you never stop being a Marine.

There is no such thing as an ex-Marine.
