Trivia

 * This jetpack is the first propulsion equipment made available to players, since the inclusion of jetpacks on the Sangheili Rangers in Halo 2 and the Jiralhanae airborne troops in Halo 3 and Halo 3: ODST.
 * It's likely that this is the T-PACK, also known as the "Thruster Pack", a Human propulsion device used in deep-space missions by the Naval Special Warfare Command and Naval Intelligence.
