Which branch of the military primarily focuses on joint firepower operations?

The United States Army is primarily focused on joint firepower operations because it plays a central role in coordinating and executing ground combat missions that often integrate various forms of fire support, including artillery, air support, and close air support from other branches. The Army's structure and training are oriented towards operating in conjunction with joint forces, utilizing comprehensive firepower to achieve mission objectives on land.

In joint operations, the Army works closely with the Navy and Air Force to maximize effectiveness, often relying on their capabilities for aerial support and intelligence while providing ground coordination. Its emphasis on combined arms tactics means that the Army regularly engages in planning and executing operations that require the integration of fire from different domains. This joint capability is critical in modern warfare, highlighting the Army's core mission to control land engagements while effectively employing firepower from all service branches.
