The Iron Curtain is a Soviet superweapon used during the Third World War.


The Iron Curtain is one of the Soviet military's most-feared creations. It gathers some sort of energy inside its furnace, which it uses to project a kinetic barrier onto armored forces. While the barrier lasts only a short while, affected targets are completely invulnerable during that time[1].
