title and rank of a senior army officer, usually one who commands units larger than a regiment or its equivalent or units consisting of more than one arm of the service. Frequently, however, a general is a staff officer who does not command troops but who plans their operations in the field.

The United States Army, Air Force, and Marines have a fourth general officer grade, brigadier general (brigadier in the British Army).

Marshall in that year and upon Omar N. Bradley in 1950. The four-star rank of general of the army of the United States was established for Ulysses S. Grant in 1866 and was bestowed later upon William T. Sherman and Philip Sheridan; the unique four-star rank of general of the armies of the United States, created in 1799 for George Washington but never held by him, was conferred upon John J. Pershing in 1919.
