In this capacity, Mr. Massicotte manages all worldwide military and governmental business.

Massicotte has transformed the Military business from an incidental business to a full service organization.

The success of Navistar's military business revolves around Massicotte's commitment to after-sale support for each and every customer. In doing so, he has expanded the dealer support network to more than 75 countries to include pre-positioning spares, diagnostic equipment and trained technicians in sensitive combat theaters around the world before vehicles are delivered; this has become the cornerstone of his success.
