**EMAC (Emergency Management Assistance Compact)** is a pioneering mutual aid network established to enhance disaster response across the United States. Formed as the first national disaster-relief compact ratified by Congress since 1950, EMAC was enacted into law in 1996 and now includes all 50 states, the District of Columbia, and several U.S. territories. This robust system allows states to provide immediate support during emergencies by mobilizing personnel, equipment, and essential resources to affected areas.

EMAC's comprehensive framework encompasses a range of services, including the Mutual Aid Support System (MASS), mission-ready packages, and specialized training through EMAC eLearning courses. It also fosters collaboration in diverse disciplines such as emergency medical services, law enforcement, fire management, and public health. Importantly, EMAC facilitates legal agreements that streamline resource sharing and protect state responders from liability. By effectively coordinating resources through local emergency management agencies, EMAC enhances state capabilities, ensuring communities are more resilient in the face of disasters.
