The Tagil also fires 9K119 Refleks (NATO designation AT-11 Sniper-B) anti-tank guided missiles in the same manner as ordinary munitions. These missiles have a range of 4-5 km and can also engage low-flying helicopters. A total of 40 rounds a carried for the main gun. .
The tank has the capacity to carry up to 40 rounds of 125mm ammunition. The MBT is also armed with a 7.62mm 6P7K anti-aircraft machine gun on a remotely controlled weapon station mounted on top of the turret to destroy stationary and moving targets. It can carry 2,000 rounds of 7.62mm ammunition and 800 cartridges. Six smoke-grenade dischargers are also fitted on each side of the turret.
This combat machine has new composite armor as well as built-in Relikt explosive reactive armor (ERA) in place of the previous Kontakt-5. The Tagil is fitted with side skirts with built-in Relikt ERA. It provides protection against tandem warheads and reduces penetration of APFSDS rounds by over 50%. There is also a countermeasures system, which triggers smoke grenade dischargers once the tank is being illuminated by a laser beam.
