- The Army was formed on June 14, 1775.
- The Continental Navy was authorized by the Continental Congress on October 13, 1775.
- The Marine Corps first appeared as the "Continental Marines" during the American Revolutionary War, formed by a resolution of the Continental Congress on November 10, 1775.
- In 1941, the Army Air Corps became the U.S. Army Air Force. The USAAF reached status as a separate arm of the Army, with equal voice with the Army and Navy in 1943.
Therefore, in the U.S., the Marines and the Air Force are the junior services, and the Army and Navy are the senior services.
(In England and some other countries, their Navies are the senior service and are referred to as such: "the Senior Service.")
