It is a welded steel turret very similar to the turret of the T-90 Main battle tank. The empty "bins" in front of the turret will house None explosive reactive armour that consists of plates of steal and rubber sandwiched together. The impact of either a shaped charge jet (High Explosive Anti Tank) or
long-rod penetrator (Armour Penetrating Fin Stabilized Discarding Sabot) after the first layer has been perforated and while the
rubber layer is being penetrated will cause the rubber to deform and expand, so deforming both the back and front plates. Both attack methods will suffer from obstruction to their expected paths, so experiencing a greater thickness of armour than there is nominally, thus lowering penetration. Also for rod penetrations, the transverse force experienced due to the deformation may cause the rod to shatter, bend, or just change its path, again lowering penetration. The turret is further protected by a new Iranian Explosive reactive Armour (ERA) similar to the Relikt ERA fitted on the T-90MS, which is likely effective against both HEAT and APFSDS rounds. The Fire Control System is a copy of the Italian TURMS-T that was exported to Syria and used to upgrade some of their T-72 fleet. TURMS-T is similar in capability to the Fire Control System found on the U.S M-1 Abrams MBTs and it uses a Laser range finder that feeds the range to target to a ballistic computer and the gun automatically elevates to ensure a high first round hit probability. TURMS-T is equipped with both day sight and thermal sight for night fighting capability. The Karrar also utilizes the 1K13-19 sight to allow the Karrar to guide the Gun launched Svir (AT-11 Sniper) anti tank missile which Iran produces under the name Tondar.
