Service dress uniforms in the U.S. air and land forces also have a different style of shoulder board, a firm material with an underlying longitudinal strap. The corresponding jacket shoulder has two small loops traversing from rear to front, and the open end of the shoulder board's strap is drawn through the two loops and affixed to the underside of the board. This effectively hides all the means of attachments, leaving a firm, finished surface. This particular style is what U.S. Air Force personnel call a shoulder board. The shoulder sleeve is called an epaulette, and the two are never confused.
