Submarine Combat Patrol insignia

The Submarine Combat Patrol Insignia is a uniform breast pin worn by officers and men of the United States Navy's Submarine Service who have completed war patrols. Such patrols were conducted during World War II.

The pin shows the broadside of a Gato-class submarine. A scroll beneath the submarine holds service stars, one gold star for each successful patrol after the first or a silver star for five successful patrols. Successful patrols are those so designated by fleet commanders.

The Submarine Combat Patrol Insignia is considered a "secondary insignia" and is typically worn in conjunction with a primary warfare badge, such as the Submarine Warfare Insignia. Personnel eligible to wear other secondary insignias, such as the SSBN Deterrent Patrol Insignia or the Deep Submergence Insignia, may only wear one insignia at a time according to their personal desire.
