The T-72B3 is Russia's recently upgraded aging T-72B tank. It can be seen as a low-cost replacement for the T-72B2 upgrade to keep the older T-72B tank operational. The refurbished and refurbished T-72B3 tank comes with new engines, new gunner sights, new fire control systems, and some improvements. Now this MBT has search capability. In 2013, the first batch of upgraded T-72B3 tanks were delivered to the Russian army. By 2016, at least 600 old tanks will have been upgraded to this standard.The fuel tank protection has been slightly improved. The T-72B3 is equipped with built-in Kontakt-5 explosive reactive armor. The same armor was also used by the T-80U, T-90, and some other main battle tanks. This armor is effective against most artillery.The tank is equipped with the same 125mm smoothbore gun as its predecessor. However, the T-72B3 auto-loader has been modified to use the newly developed ammo. The tank can fire either the 9M119 Reed whistle/Map or the 9M119m Reflected anti-tank missile, just like a regular artillery shell. Western reports of the two missiles were called AT-11 "Snipers". A total of 55 rounds are prepared, 30 rounds are stored in the automatic loader and ready for use, and the rest are stored in the warehouse
