The Air Force Security Forces Shield is a military badge of the United States Air Force Security Forces. Originally known as the "Air Police Shield" and the "Security Police Shield," the Air Force Security Forces Shield has existed since the early 1960s. The shield is worn in the center of the left breast pocket of all Air Force uniforms, or in an approximately equivalent location if the uniform does not have breast pockets. For females in dress uniforms, the shield is worn above the name tag on the wearer’s right side. The shield is usually not worn on the OCP uniform, being substituted by the "SF" brassard patch on the wearer's left arm. The Security Forces Shield placed in the same location, in a subdued tone with or without an OCP background is an acceptable alternative as well. The Security Forces shield is the primary identification for officers and enlisted members of the Air Force Security Forces.
