On November 10, 2021 U.S. Marines around the globe celebrate a 246-year legacy of battlefield prowess defined by courage, discipline, loyalty, perseverance, adaptability, leadership, and warfighting innovation. The annual birthday message delivered by the Commandant of the Marine Corps Gen. David H. Berger and the Sergeant Major of the Marine Corps Sgt. Maj. Troy Black acknowledges the generation of Marines who joined after the terrorist attacks of 9/11, who later served in Iraq and Afghanistan, and who now approach their retirement milestone. It also highlights the culture of innovation being cultivated by Marine leaders to enable the Marine Corps to remain America’s force in readiness—prepared to fight and win in every clime and place.
