Description

The United States Marine Corps. [ABOUT US] Established on September 7th, 2021, the USMC is a volunteer-only branch that fights on the front lines of battles. You can always count on us when an issue is at hand. [SOCIAL LINKS] Join our social links and help us get big. A unit is only as good as the person who poses the greatest challenge within it. We start from the bottom ranks and bring everyone up. [RANKING INFO] Upon joining the group you will possess the rank of Recruit, on the completion of Recruit Training you will receive the rank of [E1] Private and that will begin your journey here. Our motto is "Semper Fidelis" which means "Always Faithful". Once a Marine, always a Marine.

Growth

Growth history is still building. We hold one measurement for this entry. A trend needs at least two, taken days apart — so this will fill in on its own rather than being estimated. We do not publish numbers we have not measured.
