For the workaday Operational Dress Uniform (ODU), the Coast Guard did not follow the lead of other Armed Forces of the United States by prescribing rank display on chest tabs on their Combat and Working uniforms. Instead, both Officers and enlisted Guardsman wear embroidered, sew-on rank insignia on the collars of the ODU.
To correctly position the sew-on Lieutenant (junior grade) insignia, picture a line running directly through the middle of the collar point. With the insignia oriented vertically, tilt it inboard (roughly 45 degrees) and center it on this line, with the bottom of the gold bar 1-and-1/8th inches from the collar point.
The Coast Guard introduced the ODU in 2000 to lighten the seabag by having it replace the Working Blue and Blue Undress uniform. It subsequently released a second version with an untucked blouse in 2008 which was adopted by the Commissioned Corps of the U.S. Public Health Service and the National Oceanographic and Atmospheric Administrations.
