Summary
The Battle Efficiency Ribbon, or the Navy "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, 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 uniform.
