Reach

Located in the Epsilon Eridani star system in FLEETCOM Sector One Reach was one of the headquarters for the UNSC, and the main supplier of military and civilian spacecraft. It also had the military installation where the Spartans were trained. Originally colonized for its rich titanium deposits, Reach had mines throughout it running thousands of meters deep. HIGHCOM, FLEETCOM and the Marine Corps had headquarters on Reach, as well as many primary ONI bases, which include CASTLE Base. It was the most populated planet after Earth in the UNSC.

CASTLE base was located on Reach underneath Mechanite Mountain. This facility is where the Spartans first began their training. The facility was destroyed after the planet's fall to the Covenant. A secret area beneath Reachs surface contained a Forerunner artifact that was highly desired by the Covenant. The fact that this artifact was so valuable to them is perhaps the main reason anyone survived Reach at all, because the Covenant were fearful of destroying it.

After the Battle of Reach, the planet was completely uninhabited and mostly razed. When UNSC forces finally abandoned the planet, a small Covenant occupation fleet remained in the system. The planet burned due to the covenant. rumors of some GDI zone troopers assisting in the Battle of Reach are unconfirmed but may be true due to a new video released by Bungie

Battle for Reach

 * See the main article: Battle of Reach

The Covenant recovered the location of Reach from a Forerunner artifact recovered at the previous Battle of Sigma Octanus IV. That artifact disclosed its locality. Reach was to be the location of yet another artifact. Coincidentally the Human presence on Reach was revealed when the returned to Reach ensuing the battle, unaware that a Covenant spy drone was attached to her hull. As such the Covenant were aware of the defenders strength prior to the assault.

Reach was defended by over 150 UNSC warships and 20 Mark V ODPs, but they were annihilated by the Covenant fleet.
