Do you know what it's like to have indestructible tanks ripping through your base like a bull in Chinashop? No? Then let me show you how the Iron Curtain works!

The Iron Curtain is a Soviet superweapon used during the War of the Three Powers.


The Iron Curtain itself is a mysterious device which, when fully charged, generates a strange kinetic barrier. If this barrier is "dropped" on vehicles and/or structures, they become completely invulnerable as the barrier protects againt bullets, explosives, and even energy weapons. However, due to energy constraints, the barrier dissipates after a period of time, and require some time to another use afterward. Unfortuantely, the Iron Curtain's energy is too great for infantry units, and any infantry caught in its radius will be instantly killed.

It is unclear how the Iron Curtain works when seen from a scientific perspective.

Due to erasing Einstein, there is some difference between this new Iron Curtain and the "old" variant. Although its main feature hasn't been changed, the are some slight changes. The ball - as seen in GWWIII - is now encased in armor clad and no longer hovers. Instead, the ball is connected to the base structure with thick cables. However, it is possible that the ball is merely floating within its armor shell. Thanks to its armored feature, the building now can be constructed on watery surface, adding more area on construction zone if constructed.

Role in the War

The Iron Curtain was first used by Oleg (with unknown upgrade that make its effect last longer and affect larger area) to protect the Soviet headquarters in the Heidelberg castle in Germany. However, it was destroyed by the Allied Commander and Commander Lissette in operation The Famous Liberation.

Later, 7 Iron curtains were used by Premier Cherdenko to protect the space shuttle (with which he wanted to escape to the moon) and nearby Tesla tanks and V4 Rocket launchers, but all of them were destroyed by the Allied Commander and Commander Warren in the operation The Moon shall never have them.

In the Soviet campaign, it was first used by the Soviet Commander and commander Oleg to protect their troops from Allied attacks and later to strike the "traitor" Krukov (operation No Traitors Tomorrow). It was later used in all remaining Soviet missions, including protecting the Apocalypse tanks from Yoshiros King Oni and the destruction of the Statue of Liberty in New York.

In the Imperial Campaign, it should be used against the Shogun Executioner destroying the city of Odessa, but it was destroyed by the Executioner itself before it could be used in the operation Behold the Mighty Saint of Swords. Later it was used by Gregor Zelinsky to protect the Futuretech Lab in Amsterdam, but it was destroyed by the Imperial Forces (operation The Last Red Blossom Trembled).




  • In truth, the Iron Curtain effect lasts for 28 seconds. Specifically, 25 seconds after first received and 3 seconds for area effect.
  • The real "Iron curtain" was a political border in Europe separating capitalist countries from communist countries, at the end of World War 2 until 1991, when the USSR collapsed.
