Which branch of the U.S. military predominantly operates the Patriot missile system?

The Patriot missile system is primarily operated by the U.S. Army. This advanced air defense system is designed to intercept and destroy incoming ballistic missiles, cruise missiles, and advanced aircraft. The Army's specific mission involves ground-based air defense, which is crucial for protecting soldiers, military assets, and critical infrastructure from aerial threats.

While the U.S. Navy, Air Force, and Coast Guard all have their own air defense capabilities, they utilize different systems and technologies that align more closely with their unique operational requirements. The Army's responsibility for land-based air defense systems like the Patriot reflects its emphasis on protecting ground forces and ensuring the overall effectiveness of joint operations in combat scenarios.
