Which statement best describes Defense Support of Civil Authorities (DSCA)?

The correct choice describes Defense Support of Civil Authorities (DSCA) as military support in response to requests from the Federal Emergency Management Agency (FEMA). This concept encompasses the role of military forces in providing assistance to local, state, and federal agencies during emergencies and disaster situations. DSCA is a crucial mechanism that enables a coordinated response to disasters, such as hurricanes or floods, where civilian authorities require additional resources to address the situation effectively.

The focus on civilian support underlines the military's role within the framework of domestic operations, emphasizing that the primary purpose of DSCA is to assist in maintaining public safety and restoring order rather than engaging in conflict or combat situations. This context is essential in understanding the unique function of DSCA as distinct from overseas operations or foreign assistance.
