The Post Fire Station at Fort Clark is the subject of a bi-weekly feature on historic architecture in Kinney County. The building was placed on the National Register of Historic Places in 1979 and is described as compatible with the Fort Clark Historic District.
A 1944 installation map labels the structure post building No. 199, the Central Fire Station. According to the feature, the large door openings common to army fire stations were built to fit firefighting vehicles. In the 19th century, a hose cart at Fort Clark was kept in a small hose house on the site of the present post theater, and soldiers themselves put out any fires, since there were no organized firefighters.
The first organized Army fire department was created in 1917 under the Quartermaster Corps. Kelly Field, now Joint Base San Antonio, is credited with launching the Army's first fire department unit on August 20, 1917. During the 1930s, the Army began using motorized firefighting equipment and consolidated fire stations at central locations on posts.
