Lockup

"Lockup", designated Site Req//0923-4303 is the UNSC codename for a location on the Forerunner Shield World of Requiem.

Background
The site designated "Lockup" is believed to have been used as a staging, repair and refit site for mid-size Forerunner ships. Data acquisition also hints that the site may have been involved in the first deployment of Forerunner ships in the Human-Forerunner War, specifically the Didact’s own ship, Mantle's Approach.

History
During the Second Battle of Requiem, Icebreaker squad was captured and sent here; after Fireteam Crimson was captured, they were sent here as well. Later, Roland located Crimson and Miller quickly ordered a diversionary bombardment from Dalton. After escaping and killing the guards, Crimson made their way through the facility attempting to find a way to escape. Miller decided Crimson must hijack a Phantom to escape. However, after entering the next area, Roland detected Icebreaker Squad. Crimson engaged the guards, which included Promethean Crawlers. After freeing the Marines, one of them, Lieutenant TJ Murphy, said he could remotely take over a nearby Phantom. Crimson and the other Marines provided cover for him while he did so, holding off several waves of Covenant troops. Eventually Lieutenant Murphy was able to take over the Phantom, allowing Crimson and Icebreaker Squad to escape.

Crimson later returned here to deactivate a Covenant listening post. After deactivating several jammers, they found the Covenant were using a captured Army Pelican to listen in on UNSC communications. After eliminating the Covenant forces in the area, Dalton ordered a strike to destroy the Pelican. Crimson later returned to Lockup while searching for Dr. Catherine Halsey. They were dropped off with some Marines and secured the area. They moved on to the next area and eliminated the Covenant forces there as well. Spartan Dalton detected Marine IFF tags nearby, but when Crimson went to investigate they were ambushed by Covenant forces. Crimson was forced to hold off multiple waves of reinforcements including Wraiths and Hunter pairs. As they were about to be picked up, Dalton detected more Covenant reinforcements incoming. Crimson managed to hold off additional reinforcements now including Promethean Crawlers. During the fight, Poker Squad called for assistance. When Crimson defeated the enemy forces in the area they moved to the next and assisted Poker Squad in eliminating the enemy forces.

While assisting Poker, Roland detected Hawk Squad's IFF tags, and once Poker Squad was safe, Crimson was sent to investigate. After fighting through numerous Promethean forces they arrived at Hawk's position to find only their tags. Jared Miller accessed a recording on one of the tags that revealed they had been captured by Elites looking for Reclaimers. Hawk was killed while the Elites tried to activate a device. Crimson activated the device while holding off Elite reinforcements. It was soon revealed to be a map of Requiem, Roland quickly contacted Dr. Glassman and believed the map could help them free the Inifinity from Requiem.
