In 1899 the Regiment deployed to the Philippine Islands to help suppress a guerilla movement. The Regiment would return to the Islands again in 1905 and 1911. Though the 24th Infantry fought a number of battles in the Philippines, one of the most notable occurred on 7 December 1899, when 9 soldiers from the Regiment routed 100 guerillas from their trenches.
In 1916, the 24th Infantry guarded the US-Mexico border to keep the Mexican Civil War from spilling onto US soil. When it did, the 24th Infantry joined the "Punitive Expedition" under General Pershing and entered Mexico to fight Pancho Villa's forces. In 1919, rebels and troops of the Mexican government fought in Juarez, Mexico, which borders the US City of El Paso, Texas. The 24th Infantry crossed over again to engage the rebels, ensuring that no violence erupted across the US border.
