History and Meaning of the 75th Ranger Regiment Distinctive Unit Insignia

The distinctive unit insignia was originally approved on 18 Mar 1969 for the 75th Infantry. It was redesignated for the 75th Ranger Regiment on 3 Feb 1986. 

The colors blue, white, red and green represent four of the original six combat teams of the 5307th Composite Unit (Provisional), commonly referred to as Merrill's Marauders, which were identified by color. 

To avoid confusion, the other two colors, khaki and orange, were not represented in the design, however, khaki was represented by the color of the uniform worn by US forces in the China-Burma-India Theater during World War II. 

The unit's close cooperation with the Chinese forces in the China-Burma-India Theater is represented by the sun symbol from the Chinese flag. 

The white star represents the Star of Burma, the country in which the Marauders campaigned during World War II. 

The lightning bolt is symbolic of the strike characteristics of the Marauders' behind-the-line activities.
