For many years I've been collecting groups, ephemera and items pertaining to the Interwar Hawaiian Division 1922-1941. This topic illustrates the Distinctive Unit Insignia, crests and SSI patches of the Hawaiian Division and Hawaiian Department from their formation in 1922 until their disbandment on October 1st, 1941. There were some Cavalry, Infantry and Engineer units in the Hawaiian Department prior to the formation of the Division (1908-1920), but they were reassigned to the US mainland and the Philippines after World War I (except the 3rd Engineers who were continuously building the posts and fortifications on Oahu).
The primary assets used to form the Hawaiian Division, the 21st & 22nd Infantry Brigades and the 11th Artillery Brigade, came from the WWI era 11th "Liberty" Infantry Division, thus the many '11th' numbered units on their Order of Battle. The Hawaiian Division was the only 'Full' division in the US Army during the interwar years. It was organized as a square division with two infantry brigades each having two infantry regiments and supporting engineer, artillery, armor, aviation, chemical, medical, quartermaster & ordnance units. There was also a large coast artillery harbor defense and AA presence on the islands organized under the Hawaiian (Separate) Coast Artillery Brigade.
All photos and items I am displaying are from my Pineapple Army archive (you may have seen some of them 'borrowed' on the web, but the originals are in my collection)
