Join the League

The Marine Corps League (MCL) is a Marine Corps oriented organization comprised of persons who are serving, or have served honorably in the United States Marine Corps "on active duty", for not less than ninety (90) days, and persons who are serving, or have served in the United States Marine Corps reserve, and have earned no less than ninety (90) reserve retirement credit points, and United States Navy Corpsmen who have trained and served with United States Marine Fleet Marine Forces (FMF) units in excess of ninety (90) days and have earned the Marine Corps device (clasp) worn on the service ribbon, and those who earn the Warfare Device authorized for FMF Corpsmen, shall be eligible for regular membership in the Marine Corps League.


“Once a Marine, always a Marine” is familiar to us all. It is that feeling you get when you see a Marine Corps sticker on a car or a home proudly displaying the Marine Corps flag. All we need to do is knock and that Marine will be there for you. It is not just a tag line for a commercial. That flag is the embodiment of our soul. Despite our many years of service to different causes and in various times, we all have that one tangible thing in common: It is the knowledge that we have all earned the privilege to wear the Eagle, Globe, and Anchor; a symbol that will forever be seared into our hearts.


Interested individuals, who are not qualified to join as regular members of the League, may be accepted as Associate Members.
