The Army Shoulder Cord is intended to be worn on the Class A dress green or dress blue uniform jacket or Class B shirt. According to the most recent version of the Army Regulation 670-1 (AR 670-1), the blue infantry cord is the only shoulder cord currently authorized for wear on any Army uniform. The other colored cords, corresponding to the different army branches, can be authorized by unit commanders to be worn during particular events.
The shoulder cord is worn on the right shoulder and is passed under the arm and over the right shoulder under the shoulder loop, and secured to the button on the shoulder loop. In order to attach the cord, officer personnel will attach a 20-ligne button to the right shoulder seam, 1⁄2 inch outside the collar edge
