Soviet Technology Overview
The Soviet Empire focuses its efforts on large and well-armored vehicles, assault infantry with inaccurate yet deadly weaponry, Tesla's darker side, and unadultered firepower, relying on its industrial might to rapidly produce its large weapons of war with surprising speed. While Soviet laborers cannot always mass-produce the most perfectly calibrated weapons for the armed forces, the often somewhat inelegant designs they produce are effective nontheless in combat. The power is what matters, a Soviet soldier just has to find the general direction of the enemy.
Large Armored Vehicles
The Soviets deploy some of the slowest, yet most massive vehicles there are. Heavy Tanks are like a Medium's older brother, but with twice the firepower. The HIND is effectively a flying tank, capable of surviving several direct missile impacts and able to laugh off small arms fire while returning fire with a high-caliber machine gun. Missile Subs hide their massive girth beneath the waves, surfacing only when the coasts are clear or when you want to clear them. And the Mammoth Tank takes as much punishment as it thinks it can, before retaliating with dual 120mm APDS cannons and infantry-shredding "Tusk" rocket launchers; all the while repairing its internal structure in the middle of combat.
Assault Infantry
Basic Soviet infantrymen are given AK-47s that can be fired in full-auto to quickly hose down an area. The Commissar's PKM only knows full-auto. A Starshina's shotgun can unload a similar amount of firepower in a single blast, in an amazing close-range spray. Grenadiers are more than happy to bounce a grenade around a corner and down (or up!) a set of stairs, letting the fragments handle the details. Flamethrowers are even a danger to themselves with their massive fireballs; and being near even a dying Flamethrower, or Grenadier for that matter, is a losing strategy. And let's not forget about comrade Volkov and his shrapnel-spewing flak cannon, tri-shot artillery rounds, and napalm grenades. Even the Sniper has a semi-auto rifle; it may not be as accurate as the Allied Sniper's bolt-action, but it compensates with its rate of fire. The Soviet infantryman's goal is to unload his weapon, into the nearest Allied target, and to do it as fast and as unrelentlessly as possible.
Tesla's Darker Side
Nikola Tesla was known for many things. The Allied forces knows him best as the mad scientist behind the technology powering the massive Tesla Coils which defend Soviet bases. These towers are able to strike out at nearby enemies with bolts of man-made lightning, annihilating any that venture close. Man-portable versions are carried by Shock Troopers, who are quick to give an Allied trooper the final surprise of his life with a sudden jolt. And of course, who can forget the humming Tesla Tanks. The latest-and-greatest Tesla weapon system, built off the concept of the Mobile Radar Jammer but with a severe attitude, a bulkier design, and the ability to knock aircraft out of the sky.
Unadultered Firepower
There's no argument that the Soviets deploy the heaviest-hitting tanks around, with twinned cannons on the "conventional" ones to boot. It was the Soviets who first brought the silo-based atomic bomb into play, which was followed closely by the drivable atomic Demo Truck. The silo-launched missile can effectively level a base in one stroke if placed right, and the Demo Truck is no laughing matter either. The Soviet super-soldier Volkov is essentially an effort to combine the best soldier with the best weapons. But sometimes you need something a little more powerful and a little more defendable to get the damage where you want it. The MAD Tank delivers; built off the Mammoth chassis, these weapons create incredible harmonic shockwaves that will rumble the ground, shatter the foundations of buildings, devastate nearby vehicles both friend and foe alike... but ironically enough leave infantry unscathed.
