The U.S. Army Garrison, Hawaii Shoulder Sleeve Insignia, often referred to as a unit patch or simply patch, was originally approved for the Hawaiian Department on 10 January 1922 and was redesignated for times over the next seventy-plus years. It was first redesignated for the Central Pacific Base Command on 25 August 1944, followed by a change to the U.S. Army, Hawaii on 15 July 1957. It retained this designation for nearly fifteen years before it was redesignated for the U.S. Army Support Command, Hawaii on 20 November 1972. A little over two decades later, on 29 March 1994, it was given its current designation as U.S. Army Garrison, Hawaii.
A letter “H” with its vertical components curved inward to form a twice-broken circle stands for Hawaii. This stylized “H” is inside an eight-sided polygon, or octagon, which refers to the eight islands that make up the Hawaiian Group. Yellow and scarlet are the old royal Hawaiian colors.
Headquarters of U.S. Army Garrison are based at Wheeler Army Airfield, adjacent to Schofield barracks on the island of Oahu, Hawaii.
