general of the army

Noun

 * 1) A commissioned military officer of the highest rank in the United States, ranking directly above a general, and corresponding to marshal or field marshal in other countries. A general of the army is equal in grade or rank to an admiral of the fleet.

Usage notes
In the United States Army, no officer has been promoted to this rank since in 1950. General of the army is theoretically junior to the strictly honorary rank General of the Armies, which has only been awarded to George Washington after his death. In the United States Army, this rank is only available during wartime, when congress has declared war.
