Established on 16 October 1970, the Special Warfare insignia was initially issued in two grades, gold for officers and silver for enlisted. In 1978 the Silver SEAL insignia was abolished after which the Special Warfare insignia was issued thereafter. The SEAL insignia is therefore unusual in the Navy being as it is one of the very few breast insignia issued identically for both officers and enlisted personnel. This is partly due to the combined training both officers and enlisted receive, side by side, when involved in BUD/S training.
