And combat mission
The T-90S main battle tank (MBT) is a new-generation hi-tech weapon system developed drawing on century-long experience gained in world and Russian tank-building industries, lessons learned from combat use of tanks in various countries around the world, studies and analysis of their field service and intensive trials in the most severe environments.
The T-90S is a tracked combat vehicle featuring lethal armament, advanced fire control system, heavy armor protection and high maneuverability.
Its main armament is a 125mm increased-accuracy smoothbore gun with a built-in boresighting system and a quick-release barrel. The gun is stabilized in two planes and is loaded by an autoloader.
