SOVIET SPECIAL FORCES

3.5.1 Iron Curtain Charges every 11 minutes. Renders a unit or structure invulnerable for 45 seconds.
3.5.2 Nuke Charges every 13 minutes. The atomic warhead does widespread damage at ground zero. Big and unprotected targets like buildings get vaporized, but because armored units are low to the ground, airtight, made of metal, and very heavily protected, they are much less vulnerable to the effects.
3.5.3 Parabomb Charges every 14 minutes. Parabombs are really inaccurate, and unless your target is fairly large, you can forget about scoring any direct hits. Each time you drop parabombs, the plane will arrive from a different direction, making it almost impossible to predict the path of destruction. Each of the five bomblets has the explosive power of two artillery shells.
3.5.4 Paratrooper Charges every seven minutes. You can drop paratroopers anywhere on the map, even in place you've not yet explored. Use paratroopers to scout a distant area of map, or to destroy power plants and other critical buildings in an unprotected area of an enemy camp.
3.5.5 Spy Plane Charges every three minutes. The spy plane can take a lot of AA damage, so don't be afraid to send it downtown. You can use it to spot enemy air defenses by using it this way.
