Marine Corps Marks 250 Years with Commitment to Adaptation

The United States Marine Corps is set to celebrate its 250th anniversary on November 10, 2025, reflecting on a storied history that emphasizes adaptability and resilience. In a recent interview at the Marine Barracks in Washington, D.C., both the Sergeant Major of the Marine Corps, Carlos Ruiz, and Commandant Eric Smith discussed the enduring principles that have shaped the Corps since its inception.

The Marine Corps was founded in 1775 in Philadelphia, initially created to provide a versatile fighting force capable of operating on land and at sea. Today, the Corps comprises approximately 200,000 service members, including around 170,000 on active duty and 33,000 reservists. The core creed, “Every Marine is a rifleman,” remains pivotal, with Smith emphasizing that this principle fosters readiness across all ranks and specialties.

In a world increasingly defined by rapid technological change, Commandant Smith noted, “We are nothing if we’re not flexible.” This flexibility has been crucial for the Marines, who are often the first deployed in times of crisis. The ability to act swiftly and decisively has been a hallmark of their operations in significant conflicts, including battles in Belleau Wood during World War I and throughout the Pacific Theatre in World War II, as well as more recent engagements in Afghanistan and Iraq.

As the Corps prepares for its milestone anniversary, Ruiz highlighted the importance of maintaining high standards and rigorous discipline. “You have to be on scene before a crisis erupts,” he explained, reaffirming the Corps’ commitment to readiness and immediate action. Both leaders reiterated the Corps’ ethos: “The tradition is we don’t lose. We’re Marines. We don’t know how to lose.”

While the foundational values of the Marine Corps remain intact, Smith acknowledged that “lots has changed” over the years. Advances in technology, changes in military formations, and updated equipment have all contributed to the evolution of the Corps. “The only thing that is constant is change,” he stated, emphasizing that adapting to new challenges is essential for future success.

The interview also shed light on the pride and honor associated with earning the title of Marine. “You have to earn the title Marine; it’s a privilege to call yourself a U.S. Marine,” Commandant Smith asserted, underscoring the commitment required to uphold the Corps’ legacy.

As the Marine Corps looks to the future, its leadership remains focused on ensuring that the service is prepared to face the challenges of modern warfare while honoring the traditions that have defined it for two and a half centuries. The celebrations planned for this historic anniversary will not only reflect on past achievements but also reinforce the Corps’ dedication to evolving in an ever-changing global landscape.
