Wyoming Army National Guard

The Wyoming Army National Guard is the Army National Guard of Wyoming. It includes army aviation, construction engineers, field artillery and medical asset units. It was reorganized in 1996, consolidating its two field artillery battalions into a single battalion. A ribbon bridge company and rear operations center for an infantry division were added to the Guard.

It is administered by the Wyoming Military Department, part of the Wyoming state government. The Wyoming Military Department's goal is to provide a trained, quality-based force, supported by appropriate equipment, facilities and real property, technology, and services to successfully execute state and federal missions.

The Wyoming Army National Guard was established in 1870, during the Wyoming Territory period, when territorial Governor John A. Campbell authorized the division of the Wyoming Territory into three military districts. On December 31, 1871, a law passed by the Wyoming Territorial Assembly gave legal sanction to volunteer militia companies of not less than 40 men.

The first federally recognized Wyoming unit was Company A, 1st Wyoming Regiment: The Laramie Grays, organized in 1888. The Laramie Grays were followed by the organization of Company B: The Cheyenne Guard the same year. Several other units including the Cheyenne Rangers, the 1st Regiment, the Wyoming Home Guard, and the Wyoming Rangers were formed because of concerns over conflicts with Native American tribes but were short-lived.

When Wyoming became a state in 1890, constitutional provisions allowed for the formation of units in Buffalo, Evanston, Douglas, Green River, Rock Springs, Rawlins and Sheridan.
