The 25th Infantry Division (nicknamed "Tropic Lightning", "Electric Strawberry", and the "C·ªß Chi National Guard" during the Vietnam War) is a U.S. Army division based in Hawaii. The division, which was activated on 1 October 1941 in Hawaii, conducts military operations in the Asia-Pacific region. Its present deployment is composed of Stryker, light infantry, airborne, and aviation units.
The 25th Division was formed from the 27th and 35th Infantry regiments of the original Hawaiian Division. This was a pre-second World War "square division" composed of four infantry regiments. The remaining units of the Hawaiian Division were reorganized as the 24th Infantry Division. These steps, part of the Triangular Division TO&E, were undertaken to provide more flexible orders of battle composed of three regiments.
