Uniforms of the Mexican Soldier

Spanish Colonial Uniform 1767-68
Prior to the Royal Regulations of 1772 the Spanish colonial soldier's uniform looked much like other European uniforms of the period.

Soldado de Cuera (pre-1800 Presidial
The leather jacket, or cuera, was used with a leather shield (adarga), were to protect the soldiers against Indian arrows. Traditionally, the Presidial soldiers were split into two categories: the traditional soldado de cuera and their mounted counterparts, the troopa ligera (lit."light  troops").

Troopa Ligera (pre-1800 Light Troops
Mobile companies, able to cover vast areas behind the presidial line, supported the operation of the presidial company as in the case of Alamo de Parras who supported the Béjar Presidio.
