Anti-tank guns are specialized artillery designed to destroy or disable enemy tanks and armored vehicles. They typically have a high-velocity cannon that fires armor-piercing shells, allowing them to penetrate the thick armor of tanks. These guns are usually towed by vehicles or mounted on a platform for better stability and aim. During World War II, anti-tank guns played a crucial role in ground warfare, as they were often deployed in defensive positions. Examples include the German Pak 40 and the Soviet 76.2 mm ZiS-3. Despite their effectiveness, advancements in tank armor and mobility eventually diminished their battlefield relevance.
