A tank is a heavily armored combat vehicle designed for frontline warfare, combining powerful weaponry, strong armor, and mobility. Tanks are equipped with main guns (such as a smoothbore or rifled cannon), secondary weapons (machine guns or anti-air systems), advanced targeting systems, and thick armor to withstand enemy fire. Modern tanks, like the M1 Abrams, Leopard 2, and T-90, incorporate reactive armor, active protection systems (APS), and digital battlefield integration for enhanced survivability and effectiveness. They play a crucial role in offensive and defensive operations, providing firepower and support to ground forces.
