Self-propelled howitzers are artillery vehicles that combine a large-caliber cannon with a mobile platform. This design allows them to move quickly on the battlefield, providing both firepower and mobility. They can fire shells at various angles, making them effective for long-range attacks and indirect fire support. These vehicles are equipped with their own propulsion systems, which means they do not require towing by other vehicles. Self-propelled howitzers often include advanced targeting systems and automated loading mechanisms, enhancing their efficiency and accuracy. Examples include the M109 Paladin and the K9 Thunder.
