In any event, the Terminator 2 that was spotted in Syria, seen below with President Assad, is reportedly the only one Russia has that is battlefield ready.
And the fact that Russia only has one Terminator 2, and seems to have had trouble selling, one can only conjecture as to why Moscow is building a third version.

While the Terminator 2 is lighter, cheaper and easier to operate than the first Terminator, it also has less firepower and can only fire at one target at a time, while the first could fire at three targets at a time.
The first Terminator, seen below, was unveiled in the late 1990s.
The main difference between the first and second Terminators is that the first came with two hull-mounted 30 mm automatic grenade launchers in addition to all the other weapons. The first version also had a more expensive T-72 tank hull, and a turret with the Ataka missiles mounted vertically.

The Terminator 2 is manned by a crew of 3, unlike the first version of the Terminator, which had a crew of 5.
While this array of weaponry is impressive, perhaps the most important feature of the Terminator 2, unlike comparable infantry fighting vehicles, is the height of the turret.
The turret sits very high, allowing the operators to fire the weapons from less exposed positions.

Its two 30mm 2A42 autocannons can altogether fire up to 800 rounds a minute at distances of 4,000 yards, and it's 130mm 9M120 “Ataka-T” anti-tank missiles can penetrate up to two feet of armor.
It's equipped with an impressive array of weapons, including two 30mm 2A42 autocannons, four 130mm 9M120 “Ataka-T” anti-tank missiles and a 7.62mm PKTM machine gun.
It's main purpose is to protect other tanks, especially in urban areas, and was designed after the wars in Afghanistan and Chechnya, where Russian tanks were hit hard by anti-tank and rocket systems.
Russia unveiled the BMPT-72, or Terminator 2, in 2013.
