Which joint function involves delivering firepower to support operations?

• A. Movement and Maneuver
• B. Fires
• C. Protection
• D. Sustainment

Answer: (B)

In joint operations, the function that delivers firepower to support operations is the Fires function. This area focuses on employing weapons and munitions—such as artillery, close air support, missiles, and other targeting actions—to shape the battlespace, suppress or destroy threats, and enable friendly maneuver. It requires planning, target prioritization, timing, and deconfliction across domains to ensure fires achieve the desired effects with managed risk to own forces.

Movement and Maneuver is about shifting forces to advantageous positions; Protection is about safeguarding personnel and assets; Sustainment covers logistics and support to keep operations going. Those functions enable and support fires, but delivering the actual firepower is the Fires function.
