The design of the 3rd Battalion, 23rd Marines Arms incorporates heraldic symbols that reflect its purpose, locations, and affiliations. The white shield symbolizes the purity of mission in protecting the ideals and people of the Country. Scarlet trim on the shield honors the sacrifice of blood by members of the Battalion and the Marine Corps. The crossed rifles represent the Infantry mission of the Battalion and honors its World War II and Persian Gulf War service depicting the M-1 Garand and M-16A2 Rifles. The unsheathed Arabian Sword illustrates the combat action recorded by the Battalion while activated during the Persian Gulf War. The Fourth Marine Division emblem honors the command affiliation under which the Battalion was formed and normally serves. The five stars (including the fleur-de-lis) in the pattern of the Southern Cross has dual meaning. It honors the affiliation of the Battalion with the Second Marine Division to which it was assigned during the Persian Gulf War. Additionally, each star of the Southern Cross represents a city where the Battalion's companies are located. The Fleur-de-Lis represents New Orleans, where the Battalion is headquartered. The banner declaring "Non Sibi, Sed Patriae" (Not for Self, For Country) symbolizes Citizen Marine Reservists through the South who stand vigilant and ready for our Country's call. The colors of the Arms - WHITE, BLACK, GREEN, GOLD, AND SCARLET - are associated with the United States Marine Corps.
