In 1944, the suspension ribbons for both the Army and Navy version were replaced with the now familiar neck ribbon. When the Department of the Air Force's version was designed in 1956, it incorporated similar elements and design from the Army version. However, the Department of the Air Force disliked the fact that the organization responsible for designing the medal, the Institute of Heraldry, fell under the Army, which led the Air Force leadership to reject four design proposals before settling on the "heraldically confusing" Statue of Liberty. At the Air Force leadership's insistence, the new medal depicted the Statue of Liberty's image in place of Minerva on the medal and changed the connecting device from an eagle to an heraldic thunderbolt flanked with wings as found on the department's seal. Since 1944, the Medal of Honor has been attached to a light blue colored moiré silk neck ribbon that is in width and in length. The center of the ribbon displays thirteen white stars in the form of three chevron. Both the top and middle chevrons are made up of 5 stars, with the bottom chevron made of 3 stars. The Medal of Honor is one of only two United States military awards suspended from a neck ribbon. The other is the Commander's Degree of the Legion of Merit, and is usually awarded to individuals serving foreign governments. On May 2, 1896, Congress authorized a "ribbon to be worn with the medal and [a] rosette or knot to be worn in lieu of the medal." The service ribbon is light blue with five white stars in the form of an "M". It is placed first in the top position in the order of precedence and is worn for situations other than full-dress military uniform. The lapel button is a , six-sided light blue bowknot rosette with thirteen white stars and may be worn on appropriate civilian clothing on the left lapel. In 2011, Department of Defense instructions in regard to the Medal of Honor were amended to read "for each succeeding act that would otherwise justify award of the Medal of Honor, the individual receiving the subsequent award is authorized to wear an additional Medal of Honor ribbon and/or a 'V' device on the Medal of Honor suspension ribbon" (the "V" device is a bronze miniature letter "V" with serifs that denotes valor). The Medal of Honor was the only decoration authorized the use of the "V" device (none were ever issued) to designate subsequent awards in such fashion. Nineteen individuals, all now deceased, were double Medal of Honor recipients.
