An AC-130J WSO (Weapon Systems Officer) is a specialized Air Force officer on the AC-130J Ghostrider gunship, responsible for operating sophisticated sensors, managing the mission, and controlling the aircraft's powerful side-firing cannons and precision-guided munitions, providing crucial close air support, interdiction, and armed reconnaissance for special operations. They work with the Combat Systems Officer (CSO) and aerial gunners to create a common operating picture, identify threats, and engage targets using advanced fire control systems, essentially "doing the shooting" while pilots fly the plane.
