U.S. Enlisted Collar Discs


Circular No. 68 issued by the War Department on October 8, 1907 described new insignia to be worn on the enlisted service uniform. Initially two pairs of one inch bronze discs were described, a pair on each side of the collar. One disc marked with the letters U.S., and the second with the insignia for the branch of service. The discs were to be attached useing a threaded post and thumb screw nut. Circular No. 78, issued on November 17, 1909 delayed the implementation to July 1, 1910. New instructions were issued that each soldier would wear two discs with the right one being the U.S. and the left one being the branch insignia. Specific designs were approved for each branch but several specialty discs were available through private purchase. Most "unofficial" discs were banned by 1920. In 1942, the design was changed to use 2 clutches to attach the disc to the uniform. Both Timmerman and Ballou clutches can be found on initial production, but the Ballou clutch soon became the standard. Dimples were added to the face of the Ballou clutch in 1948. The "pin-back" style was never officially authorized.

Note that similar discs were used by the U.S. Forestry Service, the Civilian Conservation Corps, the American Legion, various Military schools and academies, and most ROTC programs.

Collar Disc Type 1

Type 1 Collar Discs were issued from 1910 until 1926. They were primarily issued in a bronze finish and used a screw nut to attach to the uniform. The left collar disc could contain the Regiment number and Company Letter, or number/letter combinations for special assignments. The left disc could also include the regiment number and company letter. To simplify disc production as mobilization for WW1 progressed, the Regiment number was moved to the right disc with the Company letter on the left disc. As mobilization continued and the number of units increased, both letter and number were dropped. Six background patterns have been identified but are considered manufacture variations. Army Regulations issued on October 14, 1921 stated that collar disks were to be bronze on service uniforms and gilt on white uniforms. On November 25, 1924 the bronze disks were dropped. Any discs still in service were to be polished to a bright finish. Below are typical examples.

Type 3a Collar Discs were issued from 1937 until 1943. Type 3a discs are of two piece construction consisting of a plain brass disc with a square hole in the center and a device that has a screw post to fit into the hole. A separate piece screwed on the back to hold the disc and device together. The assembly was attached to the uniform with a screw nut.
