1775-2025 Service Through Centuries
250 Years of Service: U.S. Army, Navy and Marine Corps…
Founded in 1775, these three branches of the military have played a defining role in shaping America’s story and defending its people. Two and a half centuries of service stand as proof of their dedication, sacrifice and steadfast commitment to freedom and democracy.
U.S. Army
A Legacy of Service and Resolve
The U.S. Army, established on June 14, 1775, is the oldest branch of the armed forces. From the nation’s earliest conflicts to modern operations, it has been central to America’s defense. Many of its regimental traditions still trace back to the 18th century. Its motto, “This We’ll Defend,” first used by the Continental Army’s War Office in 1778, captures its purpose: to safeguard and preserve the United States. Seen on flags and emblems, often paired with a rattlesnake symbolizing vigilance, the motto reflects a mission rooted in liberty. Born out of the fight for independence, the Army has remained the foundation of land warfare ever since.
U.S. Navy
A Legacy of Sea Power and Courage
The U.S. Navy was formed on October 13, 1775, to protect American waters and support coastal operations against the British. Its guiding words—non sibi sed patriae (“Not for self but for country”) and Semper Fortis (“Always Courageous”)—speak to values of service and courage that have endured for centuries. Today, those ideals continue to guide sailors across the globe. With more than 320,000 active personnel and a fleet that includes 10 aircraft carriers, submarines, destroyers, cruisers and support ships, the Navy stands as the world’s largest maritime force and a guardian of international waters.
U.S. Marine Corps
A Legacy of Honor and Valor
The U.S. Marine Corps was founded on November 10, 1775, at Tun Tavern in Philadelphia as a force for amphibious and maritime missions. Its motto, Semper Fidelis or “Always Faithful,” reflects an enduring loyalty to country and to fellow Marines, both in and out of service. The saying “once a Marine, always a Marine” shows how that bond carries into civilian life, where many veterans lead and inspire in their communities. For nearly 250 years, the Marines have embodied courage and adaptability, remaining an essential part of American history and global security.
A Shared Celebration of Service
The 250th anniversaries of the Army, Navy and Marine Corps invite reflection on their common values and contributions. Each branch holds its own traditions and missions, yet all strengthen the security of the nation. These milestones are more than historic—they honor those serving today, those who served before and those who will carry the torch into the future. A quarter of a millennium marks not only sacrifice and duty but also innovation, resilience and hope for the years ahead. •
