The Col. Phillip C. Delong Detachment 1267's membership consists of US  Marines, FMF Navy Corpsmen and FMF Navy Chaplains and Associate  members. 

 Members of the Marine Corps League join together in camaraderie and  fellowship for the purpose of preserving the traditions and promoting the  interests of the United States Marine Corps, banding together those who  are now serving in the United States Marine Corps and those who have been honorably discharged from that service that they may effectively  promote the ideals of American freedom and democracy, voluntarily aiding  and rendering assistance to all Marines and former Marines and to their  widows and orphans; and to perpetuate the history of the United States  Marine Corps and by fitting acts to observe the anniversaries of historical  occasions of particular interest to Marines.
