125 mm smoothbore ammunition

The following is a list of ammunition fired by the 125 mm smoothbore gun series used in the T-64, T-72, T-80, M-84, T-90, PT-91, T-14 Armata, and other tanks derived from those designs, as well as the 2A45 Sprut anti-tank gun.
APFSDS-T.
Armour-piercing fin-stabilized discarding sabot tracer or APFSDS-T rounds. Typically used against other modern tanks.
There are different ways to measure penetration value. NATO uses the 50% (This means that 50% of the shell had to go through the plate), while the Soviet/Russian standard is higher (80% had to go through). According to authorities like Paul Lakowski, the difference in performance can reach as much as 8%
3VBM3/3BM9/10.
Entered service in 1962. The projectile is Maraging steel.
3VBM6/3BM12/13.
Entered service (estimated) in 1968. Essentially the same as the 3BM9 projectile with a tungsten carbide plug.

The 9K112 Kobra (NATO reporting name is AT-8 Songster) is also fired from the 125 mm main guns of the T-64 and T-80 series of tanks
9M119 Refleks.
The 9M119 Svir and 9M119M Refleks (NATO reporting name: "AT-11 Sniper") anti-tank guided missile has semi-automatic laser beam-riding guidance and a tandem hollow-charge HEAT warhead. It has an effective range of 75 m to 5000 m, and takes 17.6 seconds to reach maximum range. Refleks can penetrate about of steel armour and can also engage low-flying air targets such as helicopters.

It has an effective range of 50 m to 12000 m. and can penetrate of steel armour after explosive reactive armour. It can also engage low-flying air targets such as helicopters.
Guided shell.
Sokol-1.
The Sokol-1 guided shell is fired from the 125 mm main gun, it borrowed design from the 152mm artillery shell 3OF75 Santimetr-M and both have very similar appearance, but with an added shaped charge cap into its design similar to the M712 Copperhead, intended to defeat heavily armoured targets. It uses the technique that is referred to as the Russian concept of impulse corrections (RCIC), an impulse steering flight control system to correct the projectile's trajectory.
3UBK14F1/9M119F1.
The 3UBK14F1 guided shell is fired from the 125 mm main gun, its design was modified from 9M119 missile, removing the rocket motor and replacing it with an extra Thermobaric warhead, turning it into a guided shell. Its range was decreased to 3.5 km, and it is claimed to be three times the explosive power of regular thermobaric variant 125 mm guided missiles.
