UNSC: The Abandon Protocol

The UNSC Abandon Protocol was used only once...

In the year of 14 A.V., the UNSC initiated the Abandon Protocol. The Abandon Protocol is when all hope is lost and the presence of the UNSC must retreat and never return. The reason was because the firos rifgen virus was uncurable and unstoppable.

Its part of the Protocol to erase all information on the UNSC database about that planet, what happened there, names, everything. Even the only known remaining Spartan IV to ever exist.

Its been millions of years since that time, and the UNSC has never returned, not even for The Survivor...
