The Battle Efficiency Ribbon, Navy "E" Ribbon, or (informally) the Battle "E" ribbon was established in July 1976 by Secretary of the Navy J. William Middendorf. The Navy "E" Ribbon denotes permanent duty on U.S. Navy ships, aviation squadrons, or units (including construction battalions) that have won a battle efficiency competition (Battle "E") after July 1, 1974. This ribbon replaces the "E" patch previously sewn on the right sleeve of the enlisted naval uniform for pay grades E-1 through E-6. United States Marine Corps personnel assigned as ship's company are eligible; embarked personnel are not.
The Navy "E" is one of the Naval service awards that does not have a corresponding medal, meaning that when in full dress (when medals are worn), the Navy "E" is placed above the right breast pocket of the uniform instead of the left. However, when in standard uniform (no medals are worn), the ribbon is placed above the left breast pocket, along with all other citations and awards.The "E" is also one of the few ribbons that is not an individual award. Instead, it is a unit award, issued to any U.S. serviceman or woman who is stationed as ship's company when the award is earned. Embarked personnel (i.e. staff elements) are not authorized to receive the award.
