U.S. ARMY 7TH CAVALRY REGIMENT UNIT CREST (DUI)

Nicknamed “Garryowen” for the instantly recognizable Irish air that it adopted as its march tune, the 7^th Cavalry Regiment was constituted originally in the Regular Army as the 7^th Cavalry. Over the course of its 150-plus years of existence, it has earned credit for participation in the Indian Wars, Mexican Expedition, World War II, Korean War, Vietnam, and Southwest Asia (First Gulf War) conflicts, and will likely earn credit for participation in either Operation Iraqi Freedom or Operation Enduring Freedom.
 
In 1957, the 7^th was reorganized and redesignated as part of the Combat Arms Regimental System, but like many other Regiments it was withdrawn from the CARS and reorganized under the U.S. Army Regimental System as a parent regiment. Today, it comprises just three subordinate units , with the 1^st Squadron and 2^nd Battalion serving in the 1^st and 3^rd Brigade Combat Teams, respectively, under the 1^st Cavalry Division; the 5^th Squadron has been assigned as an Armored Reconnaissance Squadron in the 1^st Armored Brigade Combat Team, 3^rd Infantry Division.
Also known as a unit crest or DUI, a Distinctive Unit Insignia is worn by all Soldiers (except General Officers) in units that have been authorized to be issued the device. It is worn centered on the shoulder loops of the Army Green Service Uniform (AGSU) and the blue Army Service Uniform (Enlisted only) with the base of the insignia toward the outside shoulder seam. DUIs are not worn on the Dress variations of either uniform, however.

For Enlisted personnel, the insignia is centered on a shoulder loop by placing it an equal distance from the outside shoulder seam to the outside edge of the shoulder-loop button. Officers (except Generals) wearing grade insignia on the shoulder loops center the DUI by placing it an equal distance between the inside edge of the grade insignia and the outside edge of the button.

Full guidance on wear of the DUI is found in DA Pamphlet 670-1, Section 21-22, "Distinctive unit insignia" and 21–3(d) and (e), "Beret" and "Garrison Cap," respectively.
