History . During the Korean War General " Lightning Joe " Collins , Chief of Staff for the Army , asked a group of advisors what could be done to enhance the morale of the fighting Infantryman . It was decided that they would receive special insignia , so that everyone would know that the soldier was an Infantryman who would be fighting on the front lines . A light - blue cord was created to be worn over the right shoulder of both officers and enlisted men . Also , light - blue plastic disks were issued to be placed behind the metal " crossed rifles " Infantry branch of service insignia disks . The new enhancements were first worn by the 3rd US Infantry Regiment ( " The Old Guard " ) . The light - blue cord and disks became standard for all Infantrymen in 1952 . Although some other service branches adopted colored plastic disks for their branch insignia ( e . g . , red for Artillery , yellow for Cavalry ) the blue shoulder cord is unique to the Infantry . Presentation . Today , enlisted graduates of Infantry One Station Unit Training receive their blue cord at the " Turning Blue " ceremony held the day before their Initial Entry Training / OSUT graduation , or graduation from Infantry AIT . Other branches attend a similar ceremony called " Turning Green " , but do not receive a shoulder cord . Graduates of the Infantry Basic Officer Leaders Course must complete their two week - long final FTX with a tactical road march and a mock company attack . Prior to graduation and out - processing , students have their " Blue Cord " ceremony at Freedom Hall where their blue cords are pinned on them by their platoon trainer Captain and NCOs . The staff sergeant or sergeant first class who pins on the blue cord then renders a salute recognizing the lieutenant ' s entry into the ranks of the Infantry .
