The history of conflicts involving the Texas Military spans over two centuries, from 1823 to present, under the command authority (the ultimate source of lawful military orders) of four governments including the Texas governments (3), American government, Mexican government, and Confederate government.
Since 1823, Texas forces have undergone many re-designations and reorganizations. For example, the Texas Rangers were a branch of the Texas Military Forces from 1823 to 1935 providing cavalry, special operations, and military police capabilities. Administrative control (ADCON) of the Texas Rangers was transferred from the Texas Military Department to the Texas Department of Public Safety (DPS) in 1935 where they now perform duties similar to the Federal Bureau of Investigation (FBI) for Texas as a State Bureau of Investigation (SBI).[1] The following list of conflicts reflects duty at the time as a military unit.
Conflicts in this list may apply to several categories, but they've been generally organized by the preponderance of the mission. For example, the Laredo Smallpox Riot was a civil disorder and emergency management conflict, and Operation Border Star is both a border control and counter-drug conflict.
