US Army Berlin Distinctive Unit Insignia
The design is derived from the insignia designed for the Supreme Headquarters, Allied Expeditionary Forces (SHAEF) during World War II. Upon the field of blue is the sword of liberation in the form of a Crusader's sword, flames arising from the hilt and leaping up the blade. This represents avenging justice by which the enemy power was broken in Nazi-dominated Europe. Above the sword is a rainbow, emblematic of all the colors of which the national flags of the Allies are composed.
Design approved September 6, 1983.
