VT-4 Tank: The VT-4 tank was the star of the ground weapons at the show. It uses an advanced digitized fire control system and a 125-mm smooth-bore gun that can fire a range of ammunition. With a reliable autoloader, the VT-4 needs a crew of just three. To improve its urban fighting ability, it can be equipped with a remote weapons station. It has a powerful engine. Its active protection system, with composite and reactive armor, provides maximum protection for the crew. The VT-4 is equal to Germany’s Leopard 2A6 and the U.S. M1A2.
