The Spanish-American War was fought between May and August 1898. Although relatively few (less than 300,000) served in this short war, it occurred at significant time for many family historians, during the peak period of mass migration. As a result, for many Americans, this is the first conflict in which family members may be represented.
American forces included both regular army and volunteer soldiers, the latter coming mainly from New York, Pennsylvania, Illinois, and Ohio. As a result of the Spanish-American War, Spain lost Cuba, Puerto Rico, Guam, and the Philippines to the United States.
Having fought with the U.S. against Spain, when the war ended Filipino revolutionaries expected their country's independence. Instead, the U.S. annexed the Philippines as an American territory, and war broke out between the two countries. Variously known as the Philippine Insurrection, Philippine-American War, Filipino-American War, Fil-American War and the Philippine War, this conflict lasted from 1899 to 1902.
American volunteers participating in the recently-ended Spanish-American War enlisted only for the duration of that war, so the U.S. had to recruit additional volunteers for the Philippine Insurrection. Approximately 125,000 troops served in the Philippines during the war.

The 1900 and 1930 census records can provide a useful starting point to determine if any ancestors alive at those times participated in the Spanish-American War and/or Philippine Insurrection.
Some volunteers who served in the Spanish-American War re-enlisted for the Philippine Insurrection; the Compiled Military Service Records for these soldiers will be found in records of the earlier conflict (M1087 and M871). Volunteer units for the two conflicts can be distinguished by their names: in the Spanish-American War, volunteer units were designated by state (for example, Tenth Pennsylvania Volunteer Infantry), while those in the Philippine Insurrection were designated as "U.S. Volunteer" units. African American volunteers served in the Forty-eighth and Forty-ninth U.S. Volunteer Infantry.
Another quirk of these records: the CMSR's for soldiers of the Puerto Rican Regiment of U.S. Volunteers during the Philippine Insurrection (which are not digitized or microfilmed), are included in the index to the CMSR's for the Spanish-American War (M871).
The Philippine Insurrection is the last conflict in which the War Department compiled military service records for volunteers.

The pension files for veterans of these conflicts were not microfilmed and most have not yet been digitized, but there are multiple online and print indexes that can help you determine whether a veteran or widow applied for a pension:
To better understand the differences, and determine which one(s) you should use, consult the useful NARA blog Pension Indexes Examined. Keep in mind that to make sure you've identified the correct person, it’s helpful to know the soldier’s unit, state and widow’s name.
