Introducing project “Military Insignia”, featuring top quality military heraldry designs. Here you will find designer apparel, accessories, custom postage and gifts decorated with insignia of the 40th Infantry Division (Mechanized), also known as "Sunshine Division". It is a modular division of the United States Army. Following the army's modularization the division has become a four brigade combat team division with National Guardsmen from throughout the Pacific/Western United States and Oceania. Its Division Headquarters is located at Los Alamitos Joint Forces Training Base in Los Alamitos, California. After seeing service in World War I as a depot division, it was reorganized as the National Guard division for California, Nevada, and Utah, before seeing service in the Pacific Theatre of World War II. Later, the division served in Korea and some of its units were designated for Vietnam. The division was re-designated the National Guard unit for California alone, and it continues to serve domestically as such, mostly in homeland security operations.
