NATO vs Russia: Military equipment and weapons comparison - The Economic Times
Take a look.
Armata tank: Russia's new Armata battle tank is one of the world's most advanced. More than 2,000 are expected to be in service by 2020, and was showcased in Moscow's Victory parade this year, with a 125mm cannon capable of firing 10 rounds per minute.
The Russian army
plans to acquire 2,300 T-14s in the period 2015-2020. (note that PLANNED equates neither ORDERED nor OPERATES). 2015 number built: 20+.

The Ground Forces retain a very large quantity of vehicles and equipment. There is also likely to be a great deal of older equipment in state military storage, a practice continued from the Soviet Union. However, following the collapse of the USSR, the newly independent republics became host to most of the formations with modern equipment, whereas Russia was left with lower-category units, usually with older equipment. As financial stringency began to bite harder, the amount of new equipment fell as well, and by 1998, only ten tanks and about 30 BMP infantry fighting vehicles were being purchased each year]
New equipment, like the Armata Universal Combat Platform, Bumerang and Kurganets-25 will be equipped from 2015 and replace many old tanks, BMPs, BTRs like T-72, T-90, BMP-1/2/3, BTR-80 in active service. Funding for new equipment has greatly risen in recent years, and the Russian defence industry continues to develop new weapons systems for the Ground Forces. However, for the Ground Forces, while overall funding has dramatically increased, this does not guarantee that large numbers of new systems will enter service. In the case of vehicles, as the references show, examination of the actual number of vehicles planned to be bought yearly (about 200 MBTs and IFVs/APCs) means that for a force of about thirty divisions, each with about 300–400 MBTs and IFVs, it might take around 30 years to re-equip all formations.

https://en.wikipedia.org/wiki/T-90
T-90: 350 active, 200 reserve (orders halted, 400 T-90s acquired in the early 2000s due to be upgraded)
T-80BV/U: 450 active, 3,000 reserve
T-72: 1,900 active, 7,000 reserve (around 1,300 are T-72B/BA models of which 600 upgraded to modern T-72B3 standard. Additional T-72s are brought back into service as T-80s are progressively being withdrawn)
T-64, T-62, T54/55: large numbers, reserve only.
So, in sum, 2700 active MBTs, of which only a portion has been modernized to current standards

2) Leopard 2A7 battle tank: Not all of NATO's highly advanced equipment is American (though most is) — Germany's Leopard 2A7 battle tank, which recently came into service, is perhaps the world's most well-regarded tank.
