Wyoming Army National Guard

It includes army aviation, construction engineers, field artillery and medical asset units.

A ribbon bridge company and rear operations center for an infantry division were added to the Guard.

[1] 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.

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.

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.
