Civil Air Patrol (CAP) is a nonprofit, benevolent corporation. It is the official auxiliary of the United States Air Force. Congress chartered CAP to perform certain duties for individual communities and for the nation. That charter helped establish the three-part mission that includes emergency services, aerospace education, and the cadet program. To accomplish its mission, CAP requires an informed, active senior membership trained in leadership, management, and functional tasks. The CAP Senior Member Training Program prepares members to serve their units, their communities, and their nation. All new senior members must complete Level One Orientation as soon as possible after receiving their membership from National Headquarters.
