Marines Unit Records Research

The U.S. Marine Corps suffered enormous casualties during the Pacific campaigns of World War II. The Corps’ unit and individual records provide a very detailed look at the service and sacrifice of Marines who served and came home, as well as those who served and died.

Expert researcher and WWII historian Bill Beigel can conduct a thorough search of all available Marine unit records to help you discover information at the unit level, or concerning one or more individuals who served in the Marines during World War II.
