This abandoned Extraction Facility is heavily used and guarded by UNSC.
It is core to thier military movements and production.
The Extraction Facility's Core will provide records of the UNSC's movements and production.
Take the Scrapping Yard for an assaulting point.
They will send reinforcements once you begin the assualt so it's a retrieval mission only.
Conquer the Distribution Dishes to gain control of the Air Distribution Pad.
Then retrieve the core and bring it to the Air Distribution Pad for extraction.

1st phase is foot combat
2nd phase is primarily vehicular combat
