Well fortunately there isn't really any real world evidence of how HIND would have performed in a battle against a first class opponent, what we do know is that in Afghanistan the Mujaheddin feared them until they acquired CIA supplied MANPADS which effectively neutralised them.
In other wars they have been up against insurgent forces. I couldn't find any evidence of their use in the First Chechen war , but if they performed as well as the rest of the Russian Federation forces then I don't think they will have come out of it with any credit.
On paper it carries a formidable weapon load, and is heavily armoured,but as was demonstrated by the Russian federation in the first Chechen war a lot hangs on the training of crew ,training as units, reliability of equipment, and equipment preparation, and competence of planning staff. Did the Russian army deteriorate so quickly after the fall of the Berlin wall in 1989 to it's woeful performance in three short years, I think not, I think it was an army rife with corruption, and the threat it posed in real terms not as great as some wanted it to be, of course we can speculate on that now.
Personally though, if the game exaggerates the threat they posed in the real world, I prefer to have them scaring the hell out of me in terms of how the blazes do I deal with them.
The game is very clever in terms of posing threats and not providing easy tools to deal them. e.g T80U that none will fire at , Helicopters but not enough Air defence units, overwhelming artillery coupled with a flood RECON spotting units, Intelligence that says opposing forces amount to 80 to 120 MBT's but usually amount to 200 plus
