Operation Aurora (1986-2005) was a last attempt to defeat the Sliff army. Planet Earth Fell in just 3 hours, and the only army capable of launching an attack was the Valkan army.
Then 350,000 men and 6500 tanks attacked the beaches of Valhak in Orsha. Hundreds died, but the attack was successful.
But hell had only begun, after landing, the enemy began an orbital bombardment. Humankind's only hope was the Saxon team, launched on the Vrit 1 space shuttle.
They were succesful in their effort and, the humankind have a hope again.
