Which defines how federal forces support civil authorities?

• A. Presidential directives
• B. State/federal laws
• C. Local ordinances
• D. NATO agreements

Answer: (B)

The way federal forces support civil authorities is defined by laws at both the state and federal levels. These statutes set who can request support, under what authority, and what activities are allowed or restricted. Presidential directives might guide planning or policy, but they do not establish the binding framework for domestic military support. Local ordinances govern local matters, while NATO agreements relate to international defense commitments and not domestic force support. So the legal foundation is the applicable state and federal laws that outline authority, limits, and procedures for such assistance. For context, this framework includes statutes like the Posse Comitatus Act and the rules governing National Guard use (state control under certain titles versus federal activation), which together define how and when federal forces may assist civil authorities.
