Seven Days to the River Rhine

Seven Days to the River Rhine (Russian: «Семь дней до реки Рейн», Sem' dney do reki Reyn) was a top-secret military simulation exercise developed in 1979 by the Warsaw Pact. It depicted the Soviet bloc's vision of a seven-day nuclear war between NATO and Warsaw Pact forces.

In When the Cold Breeze Blows Away, the documents of this were acquired and thus it was finally attempted, but it was started by the Coalition of the Red Star during the Last Day.
