What is the role of the Defense Coordinating Officer (DCO) in DSCA operations?

The role of the Defense Coordinating Officer (DCO) in Defense Support of Civil Authorities (DSCA) operations is to act as the primary liaison between the Federal Emergency Management Agency (FEMA) and the Department of Defense (DoD). This position is crucial during disaster responses, as it ensures effective communication and collaboration between military resources and civilian response efforts.

The DCO's functions include coordinating support efforts, facilitating the delivery of military assistance when requested by civilian authorities, and ensuring that the military's capabilities are aligned with the needs of the emergency response. By serving as the main point of contact between FEMA and the DoD, the DCO helps streamline operations and ensures a unified approach to managing the disaster response, making it essential for the success of DSCA missions.

The other options represent roles that do not align with the DCO's responsibilities: providing logistical support for military operations in combat does not relate to DSCA; commanding all civilian agencies during disasters exceeds the DCO's authority and scope; and coordinating training exercises for military personnel is outside the DCO's focus on civil support missions.
