Series 8 jetpack

The Thruster Pack, also known as the T-PACK for short, was a UNSC issue form of propulsion for use by individuals on deep space missions. Model number 050978.

Designed for long-range deep space operations, T-PACKS were still some of the riskiest equipment avaliable. They featured triple redundancy NAV systems and stabilizers. T-PACKS contain two tanks of compressed Triamino Hydrazine, which, if ruptured, would cause rapid loss of control, for which there is little a person can do. They can also be linked up to weapons such as MA5B Assault Rifles, should the wearer fire the weapon, the pack will provide enough counterthrust to keep the wearer from spinning out of control.

T-PACKS also appear to be adversely affected by radiation, if they come into proximity with unshielded radiation, they will fail.

T-PACKS have caused the dissapearance of two Spartan-II supersoldiers. One (Unit Serial #82.10923.192) was worn by Kurt-051 in 2531 on a mission in the Groombridge 34 System. It failed when it came into contact with radiation, causing him to spin out of control. Another, worn by James during The Battle of Reach, exploded when hit with projectiles from a Covenant Needler, causing him to spin out of control and dissappear as well.
