The Mexican Service Medal was also awarded to any service member who was wounded or killed while participating in action any against hostile Mexican forces between April 12, 1911 and February 7, 1917.

Although a single decoration, both the Army and Navy issued two different versions of the Mexican Service Medal. The Army Mexican Service Medal displayed an engraving of a yucca plant, while the Navy version depicts the San Juan de Ulúa fortress in Veracruz harbor. Both medals displayed the annotation "1911 - 1917" on the bottom of the medal.

The Mexican Service Medal was a one time decoration and there were no service stars authorized for those who had participated in multiple engagements. For those Army members who had been cited for gallantry in combat, the Citation Star was authorized as a device to the Mexican Service Medal. There were no devices authorized for the Navy's version of the decoration.

A similar decoration, known as the Mexican Border Service Medal also existed for those who had performed support duty to Mexican combat expeditions from within the United States.
