The mark consists of the word SUB in red letters on a yellow background, followed by the word MARINE in mottled dark green letters resembling camouflage, and the design of a submarine sandwich shown in light brown from which portions of sliced yellow cheese, red tomato slices and green lettuce emerge, bearing the name USS SANDWICH, and surmounted by the design of a submarine conning tower shown in gray and bearing a rectangular flag design in red, white and blue, with design elements resembling two eyes from which propeller-driven condiment containers have been emitted, one shown in yellow and bearing the word MUSTARD, and the other shown in light brown with no legible wording, with bubbles shown in light blue, all superimposed on a light blue design suggesting a sonar display.
