The Constabulary Uniform
pg. 51

     A distinctive shoulder sleeve insignia was designed by General Harmon using the colors of the infantry, artillery and cavalry which had originally been combined in the shoulder sleeve insignia of Armored units.  The insignia designed by General Harmon comprised a disc of gold two and one half inches in diameter, bordered with blue, with the letter "C" in blue superimposed upon the gold background, pierced with a bolt of lightning in red from upper right to lower left.  It was originally planned to wear the Constabulary insignia on the right shoulder with the Third Army insignia on the left, this plan was not found to be practicable and was later modified to provide for the wearing of the Constabulary insignia on the left shoulder and deletion of the Third Army insignia.
     On 4 Feb. 1946 General Harmon forwarded his recommendations concerning the Constabulary uniform expressing the opinion that the uniform recommended would present a distinctive appearance, particularly with the leather belt, shoulder strap, and patch, and at the same time would not depart radically from the standard equipment worn by American officers and soldiers.
