Also called a “unit crest” or DUI, the Distinctive Unit Insignia of the Guam Army National Guard Element, Joint Force Headquarters features a green and yellow tripartite gateway with its center gates open, a reference to the Guam seat of government and how accessible it is to the people of Guam. A demi-sun behind it is a visual representation of the fact that is exactly a half-day ahead of the United States on the on the Greenwich Mean Time standard.
The scarlet archway is taken from the top half of the border of the official seal of Guam (which serves as the basis for the design of the Guam Army National Guard Shoulder Sleeve Insignia, or unit patch). Its red hue is an allusion to the reality that Guam did fall under enemy occupation and natives of the island died while supporting America during World War II.

This Distinctive Unit Insignia was first approved for the Guam Army National Guard on 10 September 1984. It was redesignated twice, first on 18 December 1984 for the HQ and HQ Detachment, Territorial Command, Guam Army National Guard and then on 1 October 2003 for its current authorization for the Guam ARNG Element, Joint Force Headquarters.Distinctive Unit Insignias are 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 (ASU, Enlisted only) with the base of the insignia toward the outside shoulder seam. Current regulations do not permit the DUI to be worn on the Dress variations of either uniform, however.
More 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.Related Items
