I, in my stumbling through the highways and backroads of the internet, occasionally stumble across things that I just… like. Things that are just fun and informative. Koala Explains is one such channel and here he is talking about some mainline russian armor hardware. The T-90, specifically a little bit of the background and one of the T-90’s active defenses.
The T-90  is a third-generation Russian battle tank that entered service in 1993. The tank is a modern variation of the T-72B and incorporates many features found on the T-80U. Originally called the T-72BU, but later renamed to T-90, it is an advanced tank in service with Russian Ground Forces and the Naval Infantry. The T-90 uses a 125 mm 2A46 smoothbore main gun, the 1A45T fire-control system, an upgraded engine, and gunner’s thermal sight. Standard protective measures include a blend of steel and composite armour, smoke grenade dischargers, Kontakt-5 explosive-reactive armour and the Shtora infrared ATGM jamming system. It was designed and built by Uralvagonzavod, in Nizhny Tagil, Russia. Since 2011, the Russian armed forces have ceased any further orders for the T-90, and are instead increasing their numbers of the T-14 Armata that began production in 2016.
While not their most modern piece of armor anymore it is still a mainstay of the Russian armored contingent and a neat piece of tech.
