What are the four core tasks the Army supports in DSCA and homeland security operations?

The choice highlighting domestic CBRNE attacks, disaster response, civil law enforcement, and designated domestic support accurately reflects the four core tasks the Army is trained to perform during Defense Support of Civil Authorities (DSCA) and homeland security operations.

In the context of DSCA, CBRNE (Chemical, Biological, Radiological, Nuclear, and Explosives) incidents involve preparedness and response capabilities that the Army can offer in the event of attacks or accidents involving hazardous materials. Disaster response generally encompasses aid and assistance during natural disasters, where the military may provide logistical support, personnel, and resources to aid civilian authorities.

Civil law enforcement indicates the role of the Army in supporting civilian law enforcement, particularly in situations requiring additional manpower or specialized skills to maintain peace and ensure public safety. Designated domestic support involves the Army's engagement in operations that are authorized to assist civil authorities in maintaining order and safety within the homeland, particularly during crises.

This combination of tasks ensures a comprehensive approach to aid civil authorities in safeguarding communities, making this choice the most relevant in the context of the question.
