The Mexican Border Service Medal was established by Act of Congress (Public Law 193, 65th Congress) on July 9, 1918.

The Roman sword symbolizes war or military strength and is sheathed to indicate service in the United States rather than in actual combat. The wreath represents achievement. The rifles, sabers, and cannons represent the Infantry, Cavalry, and Artillery. The ribbon colors are the same as used in the Mexican Service Medal.
