Definition
A shoulder mark is similar to a shoulder board, typically a strip or patch worn on the shoulder of a uniform to indicate rank, branch of service, or other affiliation. They are common in military and law enforcement uniforms. Think of it as a quick identifier worn on the shoulder. Unlike more elaborate shoulder boards, shoulder marks may be simpler in design. Their primary function is to convey information at a glance. They might include stripes, symbols, or letters.
