The Colorado State Defense Force, formerly known as the Colorado State Service, is the current, albeit inactive state defense force of Colorado. The Colorado State Defense Force served as the stateside replacement for the Colorado National Guard while the National Guard was in federal service during World War I and World War II.
History
=World War I=
In the summer of 1917, the Colorado Reserve Service was organized as a unit consisting of five companies: companies A, B, and C of the Third Regiment; and A and B of Colored Infantry. They were called into active service for guard duty on public utilities and reservoir projects on 1 August 1917. The largest total of men on active duty was 409 in September 1917; the smallest was 168 in October 1918. After the war, late in 1918, the 3rd Colorado Infantry and Troop "A" of the Colorado Cavalry received federal recognition as National Guard units.{{cite web |url=http://www.militarymuseum.org/HomeDefenseStudy.pdf |title=US Home Defense Force Study |last1=Tulenko |first1=Thomas |last2=Chase |first2=Bradley |last3=Dupuy |first3=Trevor N. |last4=Hayes |first4=Grace P. |date=March 1981 |website=California Military Museums |publisher=Historical Evaluation and Research Organization |accessdate=22 December 2015}}
