The Oldest Branch of the U.S. Military: The U.S. Army
The United States Army holds the title as the oldest branch of the U.S. military, founded on June 14, 1775, by the Continental Congress.
Origins and Significance
The U.S. Army was established to support the American Revolutionary War effort, marking the start of its significant role in American history and military operations. As the senior U.S. military service, it has a continuous history unmatched by any other branch of the U.S. military.
Age Comparison with Other Services
The U.S. Army is over two decades older than the United States Navy, which was founded on March 27, 1794. This difference in age is significant and often emphasized in both military and historical contexts.

For our allies in the United Kingdom, the seniority is reversed, with the Royal Navy being founded in 1546 and the British Army marking 1 January 1660 as its origin date. However, these facts from across the pond are not wasted on the U.S. military, which proudly maintains its history and traditions.
Notable Units and Their History
The U.S. Army itself, tracing its historical roots back to a single guard unit and a training center at West Point, is still considered the senior branch in the U.S. military. However, specific units within the Army can trace their origins to an even earlier date. The Massachusetts Army National Guard, for example, has elements tracing back to 1636, making it one of the oldest military units in the country.
The U.S. Marine Corps and Other Services
The U.S. Marine Corps, founded in November 1775, is the second-oldest branch of the U.S. military. Although it was abolished and reestablished multiple times, it remains a separate and significant branch. The U.S. Navy, formed in October 1775, was similarly founded and disbanded, but it was reinstated in March 1794. As a result, Navy units follow Marines in parades, and the Marine Corps flag stands to the right of the Navy flag in ceremonial events.
The U.S. Coast Guard and the Air Force
The U.S. Coast Guard, formed in August 1790, is technically the third-oldest branch, following the U.S. Army and U.S. Marine Corps. However, its status as an independent branch was formalized much later, and it is often considered for parades and ceremonial purposes. The U.S. Air Force, founded in 1947, is the youngest branch of the U.S. military, with its roots tracing back to the Signal Corps in 1907.
The Introduction of the Space Force
The recent addition of the U.S. Space Force in December 2019 has further reshaped the order of precedence within the U.S. military. Although the U.S. Coast Guard marched before the Space Force for parades and formations, the new Space Force has moved ahead in precedence, particularly for ceremonial events and flag placement. The USAF remains the youngest branch as it forms part of the Army, although it has deep historical roots.
Conclusion
The U.S. Army's long and storied history makes it the oldest branch of the U.S. military. From its humble beginnings to its current status as a vital branch, the Army has played an integral role in American military history. Understanding the origins and history of each branch of the U.S. military, including the U.S. Army, helps to appreciate the depth and complexity of the nation's defense and military traditions.
