WASHINGTON DC, November 8, 2007 – In testimony today before the House Armed Services Committee, Archie Massicotte, president of International Military and Government, LLC told Members of Congress about the company’s unique capacity to rapidly ramp up production of International ® MaxxPro ™ Mine Resistant Ambush Protected vehicles (MRAP).

Massicotte said the company—a wholly-owned affiliate of Navistar International Corporation (Other OTC: NAVZ)—has delivered more than 400 MaxxProTM MRAP vehicles within 165 days of its first contract award on May 31, 2007.

“We delivered a total of 407 MaxxPro MRAP vehicles since receiving our first contract Memorial Day and we are on our way to 500 vehicles per month by February,” said Massicotte. “We have capacity for further growth.”

In total, the U.S. Marine Corps has ordered 2,971 MaxxPro MRAP vehicles to be delivered by April 2008. Currently, there are 95 MaxxPro’s in theater and more than two dozen International Field Service Reps are on the ground supporting the vehicles.

In addition to vehicle awards, the company has won contracts to supply parts, service and training for the MRAP program. Approximately 58,000 parts and components were shipped to the military in the past 45 days. Overall, these contracts total nearly $1.7 billion.

Last year, Navistar built more than 160,000 trucks and school buses and 560,000 diesel engines.

“We bring our unique commercial truck expertise and manufacturing capacity to everything we do for the military,” said Massicotte.

The industrial capacity of the Navistar family is far-reaching. The company has nearly 1,000 dealership locations worldwide, with facilities in 75 countries outside North America including Iraq and Afghanistan.

“We have been making trucks and engines for more than 100 years, and we have been providing America’s Armed Forces with reliable, sturdy vehicles since World War I. The collaborative effort with the military is extraordinary and we are pleased to continue our service with the MaxxPro MRAP vehicle. This opportunity is more than a contract, it’s a privilege,” concluded Massicotte.
