The Karrar (Striker) is an Iranian main battle tank. The tank was announced on 12 March 2017. At the announcement, it was stated that it possessed an electro-optical fire control system, a laser rangefinder, ballistic computer and could fire at both stable and mobile targets in day or night.
Despite its visual similarity to the T-90, Iran has not made any arrangements to acquire a license agreement with Russia to manufacture T-90s for the Iranian Army.Main armament of the Karrar consists of one 125mm smoothbore gun fitted with a fume extractor and a thermal sleeve.[8] A remotely operated weapon station armed with a 12.7mm machine gun is mounted on the roof of the turret. The main gun is able to fire anti-tank laser-guided missiles.[9] An autoloader is also installed, removing the need of a loader.[10]

The Karrar is fitted with latest generation of armour, with ERA (Explosive Reactive Armour) at the front of the hull and turret. There is also armour plates on the upper part of the suspension and slat armour at the rear of the hull and turret.[1]

External fuel tanks can be attached to the rear in order to extend its range.[8]
