This is an old mission of mine, many of which I made during 2007-2011. This mission was intended to be the last Allied mission. Clear the way for your beloved MCV, and wipe out everything.
If you're lucky, you might even get nuked a few times ;).
EDIT: Fixed a bug caused by old custom text triggers I was supposed to remove anyway, displaying misleading text "Find Einstein" during the mission, which has nothing to do with the mission.
