Military Reservation 01478-B
The Military Reservation 01478-B on Reach was set up by the UNSC as one of their training facilities for Marines and ODSTs. The SPARTAN-IIs trained here as well in 2517 upon their initial induction into the SPARTAN-II program. In 2552, this was the location where John-117 tested his new MJOLNIR Mark V armor, equipped with Energy Shields. During the Fall of Reach, Frederic-104 used this area as a staging point for his Spartans.
It had the reputation for being known as "Painland". It featured a large obstacle course, with a run over ten acres of jagged gravel, a place called the "razor field" where the trainees had to crawl in the mud under razor wire with bullets flying inches over their heads. Finally there was a course called "The Pillars of Loki" which consisted of a forest of ten meter high poles placed at random intervals, usually with booby traps strung on, to teach the importance of moving slowly and keeping one's eyes open.
