M-Spec reentry pack

The M-Spec Reentry Pack, also known as the Reentry Unit, is a piece of UNSC equipment. It was used by SPARTAN-B312 to safely drop from orbit onto the surface of Reach after Operation: UPPER CUT.

According to the Halo: Reach Legendary Edition developer commentary, the reentry pack is integrated into the YSS-1000, hooking onto the pilot's back as soon as they enter. However, during the launch cutscene, there is no reentry pack visible on the cockpit seat, or anywhere within automatic clamping distance of the pilot.

Trivia

 * The beginning cutscene of Exodus shows that it is possible to holster a sidearm inside the reentry pack.
