"The main reason for air conditioning in the tanks is not the crew, but the electronics. Russia was asked to develop and install air conditioning but were unable to create a system that could handle the Indian climate. That failure caused a lot of damage to the Russian and foreign made electronics in the Indian T-90s," particularly (tank's) thermal imaging systems

"Much of the border between India and Pakistan is desert, and most of India's armored units are stationed there. The problem is that while the T-90 had Russian developed air conditioning (something new in Russian tanks), it cannot handle the 100+ degree heat in tropical India. The Russians were unable to develop a suitable upgrade because there was no room inside the tank to install a more powerful, but larger, cooling system. The American M-1 air conditioning has been able to handle extreme heat, so the Indians knew it could be done and eventually found a supplier who could build a system that worked and fit into the space available.
"The T-90 went into low level production in 1993, but was too expensive for the Russian army to buy more than a few of them. India eventually became the biggest user. The T-90 is based on the T-72, but has composite armor (plus reactive armor) and better electronics. The 50 ton tank uses a 125mm smooth bore gun, and can also fire the 9M119M Refleks-M missile (to 4,000 meters) at ground or air (helicopter) targets. * * * [First delivered in 2001 but gradually making its own under license, India] ha[s] over 1,600 of them
"One big reason India bought the T-90 is the 9M119 (AT-11) anti-tank missile, which weighs 23.6 kg (52 pounds), has a range of 100-4,000 meters and uses semi-automatic laser beam guidance system (the gunner keeps his sight on the target and the missile homes in on that.) Maximum time of flight is about 12 seconds. While the missile has a tandem warhead, making it useful against tanks with reactive armor, it can also be used against helicopters. The missile warhead can penetrate about 700mm of armor.
"When they work, the T-90s are more than a match for anything the Pakistanis or Chinese have.
