The U.S. Armed Forces consist of six distinct branches, each with its own history, duties, and areas of expertise. While every branch serves the same purpose—to protect and defend the United States—they each carry unique responsibilities and traditions. Learning more about these branches helps us better appreciate the commitment and service of America’s veterans and active-duty personnel.
Army
The U.S. Army is the nation’s largest and oldest military branch, tracing its origins to the Revolutionary War. As America’s primary land force, the Army includes infantry, armored units, and artillery. Specialized groups such as the Army Rangers and Army Mariners receive advanced training to complete specialized missions both on land and at sea.
The U.S. Army Flag
The Army flag features a blue rendering of the War Office Seal on a white background. Below the seal is a red scroll reading “United States Army,” and beneath that, the year 1775, marking the formation of the Continental Army.
Navy
The U.S. Navy operates on, above, and beneath the world’s oceans, protecting sea lanes, supporting global trade, and projecting U.S. presence abroad. Naval forces include aircraft carriers, submarines, destroyers, and other vessels. Among its elite units, the Navy SEALs—Sea, Air, and Land Forces—are renowned for their demanding training and versatile mission capabilities.
The U.S. Navy Flag
The Navy flag displays the official Department of the Navy seal—featuring an eagle, anchor, and ship—on a dark blue background. A yellow scroll beneath the seal reads “United States Navy” in blue lettering.
Marine Corps
The U.S. Marine Corps works under the Department of the Navy but stands as an independent branch. Marines specialize in amphibious warfare and rapid deployment, serving as a bridge between naval and land operations. They are often the first to arrive during global crises or conflicts.
The Marine Corps Flag
The Marine Corps flag features a scarlet background with an eagle, globe, and anchor emblem in gray and gold. A scarlet ribbon beneath the emblem reads “United States Marine Corps.”
Air Force
Originally part of the Army, the U.S. Air Force became an independent branch in 1947. It manages air and space operations, deploying personnel and equipment worldwide within hours. Beyond aviation, the Air Force also leads in engineering, cybersecurity, and technology innovation.
The Air Force Flag
The Air Force flag showcases the branch’s official crest and shield, surrounded by thirteen white stars symbolizing the original colonies, all set against a field of blue.
Coast Guard
The U.S. Coast Guard operates under the Department of Homeland Security during peacetime and the Department of the Navy during wartime. Its duties include patrolling domestic waters, enforcing maritime law, preventing smuggling, and conducting search-and-rescue missions.
The Coast Guard Flag
The Coast Guard flag presents a dark blue version of the Great Seal of the United States on a white background, with “United States Coast Guard” above and the motto “Semper Paratus” (“Always Ready”) and the year 1790 below.
Space Force
Established in 2019, the U.S. Space Force is the newest military branch. It focuses on protecting U.S. interests in space, including satellite systems, communications, and space defense operations. The branch organizes, trains, and equips forces to conduct military operations in space.
The Space Force Flag
The Space Force flag features the branch’s seal on a black field. The emblem includes a delta wing, globe, orbit, Polaris star, and constellations, with “United States Space Force” and the Roman numerals “MMXIX” denoting its founding year.
National Guard
Although not one of the six official military branches, the National Guard plays a crucial role in U.S. defense. Each state and territory has its own National Guard, composed of Army and Air National Guard units. The Guard assists in national defense, humanitarian efforts, and disaster relief at home and abroad.
The Army and Air National Guard Flags
The Army National Guard flag bears its official seal on a white background, while the Air National Guard flag displays its shield beneath an eagle on a blue field surrounded by stars. Both flags symbolize service, duty, and readiness to defend the nation.
