The T-90 is a Russian main battle tank and presently the most advance tank in service with the Russian Ground Forces and Indian Army.
The T-90 has a small profile which makes it a harder target to hit. Significant drawback of the T-90 is that due to it's carrousel-type autoloader ammunition is stored in the main compartment, rather than a separate compartment with a blow-out panels.
The T-90 is not as accurate against long-range targets, however it can launch anti-tank guided missiles in the same manner as ordinary munitions.
The T-90MS Tagil is a recent version with new armor, new engine, new gun, improved turret, updated observation and aiming system.
