War of 1996
On July 2, 1996, a supreme commander was sent by his/her Queen and arrives with his Colony ship, and hidden behind the moon and using Earth's satellites to transmit a countdown signal to when he and his aliens were to attack with their destroyers, resulting the destruction of many cities (including Washington D.C., New York City, Los Angeles, and Houston).

On July 4, 1996, the supreme commander gets his/her orders from the Queen to attack Area 51. However, Captain Steven Hiller and David Levinson takes a captured Attacker and gets into the Colony ship, where they upload a virus into the central computer of the alien mothership, renderless all alien ship to be vulnerable to firepower by the military. This allows several planes (led by President Thomas Whitmore, who was a combat pilot himself) to take down the City destroyer in order to save Area 51 and its occupants. However, as Hiller and Levinson are about to leave, the supreme commander soon learns about their presence, but they fire a nuke to the Colony ship's core before making a close escape. This causes the mothership to finally explode, killing the Supreme Commander and the remaining Harvesters on-board, ending the invasion.
