A Silver color metal and enamel device 1 1/8 inches (2.86 cm) in height overall consisting of a shield blazoned: Per chevron Azure and Gules in chief two crossed bayonets Argent and in base a powder horn Or with string looped and inclosing a mullet of six points of the third. Attached below the shield a Silver bipartite scroll inscribed "DESTROY IN DEPTH" in Blue letters.
Crossed bayonets allude to Infantry and combat, and the powder horn is an American symbol for readiness. The star denotes leadership and the six points refer to the composition of the unit from a number of localities. The colors blue and white, and red and gold, are from the wreath and crest of the Oregon Army National Guard, and are used to refer to the unit's home.
The distinctive unit insignia was approved on 2 July 1981.
