bases. Student airmen leaders at technical training bases (sometimes called "ropes" in reference to the aiguillette) also wear aiguillettes, with green representing the lowest level of student leadership, yellow representing the intermediate level of student leadership, and red representing the highest level of student leadership. Students wearing a white rope are commonly referred to as chapel guides, and are charged with providing social or moral support to their fellow airmen. Airmen who wear the black rope are experts in drill, choir, or ceremonies, and pride themselves on appearance and uniform wear. Airmen who wear a blue and white rope are members of the drum & bugle corps for their base. In the United States Air Force, honor guard members wear a silver aiguillette on the left shoulder. Other military cords The aiguillette should not be confused with the fourragère, which is worn by soldiers and Marines who are assigned to units that were awarded certain decorations by the French and Belgian governments for valorous conduct in the First and Second World Wars. Nor should it be confused with the Schützenschnur, a multi-weapon marksmanship decoration awarded by Germany to qualifying soldiers of NATO countries serving in Germany. A similar, albeit thicker, device, the Infantry Blue Cord, is worn on the right shoulder by all enlisted soldiers and officers in the United States Army whose primary Military Occupational Specialty is infantry. Many military units wear dress lanyards. References General references Arnold, Janet: Patterns of Fashion: the cut and construction of clothes for men and women 1560–1620, Macmillan 1985.
