Former Soviet Army

This amphibious tank's strengths are its speed and amphibious capability. Without them, it would be totally outmatched on the modern battlefield. These are capable to fight at night. Its 76.2 mm gun is underpowered by modern standards. It's armor resists only small arms fire.
The T-34 was the best Russian tank of WWII! This was heavily exported to Warsaw Pact nations after the war. If you see these in Russia, it would be in a museum, but it may very well be in the modern military of weaker countries.
T-54 and T-55
Its main gun is 100mm. Its machine guns are 12.7 mm AA MG, 7.62 mm coaxial MG, 7.62 mm bowmounted MG. These old Russian-built main battle tanks would be killed easily by today's modern tanks. These are capable to fight at night. Nevertheless, these medium tanks are still used by weaker militaries.
Like the T-55, the T-62, medium tank, has a 580-hp, V-12, water-cooled diesel engine. The T-62 has the standard 7.62 mm PKT coaxial machine-gun with a range of 1000 meters. The T 62M also mounts a 12.7 mm antiaircraft DShK machine-gun. The DShK has a range of 1500 meters against ground targets and a slant range of 1000 meters against aircraft. The T-62A also has a stabilized 115mm main gun; it enables the gunner to track and fire on the move with improved accuracy.
The T-64 was fielded in 1967. At the time it was fairly innovative design, incorporating both an autoloader and advanced armor. It had a very long production run and numerous variants were produced. T-64 is closely related to the T-72. The T-64 was produced solely for the USSR, while the T-72 was slightly less capable and exported world-wide. Its armed with 125mm main gun / missile launcher, 12.7mm AA MG, 7.62mm coaxial MG, smoke grenade dischargers. These tanks have been the basis for the new Russian tanks.
This Russian made tank is a relative of the T-64. Its top speed is 60kph. It has a 125mm main gun, smoke grenade dischargers, and its equipped with 1 machine gun on the outside for killing infantry, and the commander of the tank has his own machine gun. These tanks have many, many, many, many varieties because it was exported to so many countries and was changed, like the M-84.
An updated copy of the Russian T-72, its top speed is 70kph+, and is also equipped with a machine gun. It has great acceleration and improved power-to-weight ratio. Its an advanced T-72. This tank was made by the Yugoslavs.
Its armed with 125mm gun / missile launcher, 12.7mm AA MG, 7.62mm coaxial MG, smoke grenade dischargers. Its armour is classified, and is one of the best Russian tanks. Its better armed, armoured, faster, and more reliable than the T-64 and T-72.
T-84 Black Eagle
The T-84 Black Eagle is based on the T-80U but has a new turret. It is problably only intended for export and will not be part of the inventory of the Russian army. This is a new tank, armed with a 125mm smoothbore main gun, and a missile launcher.
This tank has been tentatively approved for production and adoption as a standard tank, alongside the T-80U, for the Russian army. The T-90 uses the gun and 1G46 gunner sights from T-80U, a new engine and thermal sights. Protective measures include Kontakt-5 ERA, laser warning receivers and the SHTORA infrared ATGM jamming system. Its armed with 125mm gun or a missile launcher, 12.7mm AA MG, 7.62mm coaxial MG, smoke grenade dischargers. This design will be made into more production soon. Right now Russia's best tank that they have many of is the T-80. There are few T-84's and T-90's in the Russian military.

The main armament comprises the 125 mm two-axis stabilized smoothbore tank gun with automatic loader and the coaxial 7.62mm machine gun. Nowadays, a trend has appeared in the development of world's armor materiel: to install powerful armament with highly effective sighting equipment on lightweight combat vehicles. The 2S25 self-propelled antitank gun, developed at the Volgograd Tractor Plant JSC, fully complies with this trend. It is intended for use by subunits of ground forces, airborne troops and amphibious landing parties to fight hard-skinned materiel and manpower of the enemy. The new gun can independently march over a distance of 500 km and be carried by military transport aircraft and amphibious ships, paradropped with the crew seated in the vehicle, negotiate water obstacles at sea state up to 3 with the delivery of gun fire when afloat within a sector of +35 degrees and climb on amphibious ships from water under its own power during the accomplishment of a combat mission. Possessing a high power-to-weight ratio, it can operate in high mountains and various climates, while the installed rubber-clad shoes or snow-riding tracks expand the vehicle capabilities. The main armament comprises the 125 mm two-axis stabilized smoothbore tank gun with automatic loader and the coaxial 7.62 mm machine gun.

The SA-15 GAUNTLET (9K331 Tor) low-to-medium altitude SAM system is capable of engaging not only aircraft and helicopters but also RPVs, precision-guided weapons and various types of guided missiles. Although it is an autonomous system it can be interfaced into an integrated air defense network. SA-15b is designed to be a completely autonomous air defense system (at division level), capable of surveillance, command and control, missile launch and guidance functions from a single vehicle. It can launch 2 missiles of 8 at anytime of the day at any weather. This is one of the most advanced SA system for the Russian army.
Shoulder-fired SA Rockets
SA-7, SA-14, SA-16 are all shoulder launched rockets at air units. Don't think because they are shoulder launched that they suck. They can be heat sinking missiles, infrared seekers, and can go long ranges. The SA-16 hit a Harrier in Desert Storm. The soldiers that have these are known as rocket soldiers.
