About Defense Services

Regional Defense Services, LLC is a subsidiary of Regional International and a Navistar Defense Parts Center. Regional Defense Services is determined to provide our hard working men and women I the military the parts and supplies they need to get the job done and to get home safe.

We are proud to be a Parts Center for a company that has been answering the call since World War I. While International Harvester started in farm equipment, the company was quickly pressed into service to produce military vehicles for World War I. They gained even more valuable military experience when they switched over the entire commercial operations during World War II to produce M-series trucks for the Marine Corps and Navy. International’s earned a reputation for toughness and durability under extreme battlefield conditions. A reputation that lives on today in the International brand military vehicles.

Regional Defense Services and Navistar Defense parts are your best source for all your spare parts. The online parts catalog provides a listing of more than 700,000 spares available day and night for nearly any military vehicle.
