SHIELDThe medium blue of the shield represents the Pacific Ocean, the Cutter's area of operations and Guadalcanal, the location of Petty Officer Munro's service, during WWII. The pile suggests the prow of the ship. The red star within the yellow star signifies the Marine Corps. The pile, bomb and star allude to Petty Officer Munro's heroic action placing his ship between enemy fire and the beachhead, where the remaining soldiers, pinned on the beach, waited to be evacuated. The lion head highlights Petty Officer Munro's courage and his determination to complete the mission. The reversed star commemorates the Medal of Honor awarded to Petty officer Munro for heroism.
The combined elements refer to USCGC Munro's multiple mission capability. The trident, a symbol of sea prowess, represents the cutter's mission of national defense. The sword denotes MUNRO's readiness to promote the safety of life, property and enforce maritime law. The lightning flash highlights the ship's state of the art communications, enabling USCGC Munro's effectiveness as a floating command center.
The Western Hemlock pine branches, from the state tree of Washington, represent petty Officer Munro's home state.
