Self-Propelled Anti-Aircraft Systems (SPAAGs) are military vehicles designed to detect and destroy aerial threats, such as enemy aircraft and drones. These systems combine artillery and radar technology, allowing them to track and engage targets while on the move. SPAAGs are typically equipped with automatic cannons and sometimes missiles, providing a versatile defense against low-flying threats. These systems are crucial for protecting ground forces and critical infrastructure from aerial attacks. By being self-propelled, they can quickly reposition to respond to changing battlefield conditions. Examples of SPAAGs include the ZSU-23-4 Shilka and the M163 Vulcan Air Defense System.
