• A gold color and metal enamel device 1 1/8 inches (2.86 cm) in width overall consisting of a scarlet arch with the motto "A' ADAHEN I TANO" in gold letters enclosing a triple arch gateway of the Spanish colonial period in gold metal with gold demi-sun on a blue field behind it and green field within the gateway arches, all upon a heraldic torse of gold and blue.

• The gateway, its center gates open to the horizon, symbolizes the Guam seat of government and its accessibility to the Guamanian people.
• The demi-sun alludes to the fact that, in terms of time, Guam lies half a day ahead of the continental United States.
• The archway is borrowed from the upper half of the border of the official Guam seal (the basis for the Guam Army National Guard shoulder sleeve insignia) to signify support.
• The red of the arch refers to the fact that Guam fell under enemy occupation, and Guamanians died for the American cause in World War II.
• The motto means "Guardians of the Land."

• The distinctive unit insignia was originally approved for the Guam Army National Guard on 10 September 1984.
• It was redesignated for Headquarters and Headquarters Detachment, Territorial Command, Guam Army National Guard on 18 December 1984.
