Physical restraints are devices used for keeping people in a helpless state while in captivity.

Human restraints

Humans have traditionally used a multitude of restraints such as handcuffs and rope to keep individuals at bay. The Neural-inhibitor collar is a UNSC device used to paralyze dangerous prisoners, and its practice has been used by United Rebel Front to subdue SPARTAN-IIs. Buckmesh is a particularly strong material used to contain prisoners of gangster Thin Kinkle, yet not strong enough on its own to stop a Spartan-I.

Covenant restraints

The Covenant has been known to use items such as shackles and contained beams of energy to hold prisoners. When Thel 'Vadam was tortured as punishment for letting Installation 04 come to destruction, he was kept restrained in a pair of hovering shackles apparently made of energy. A stasis beam device in the Sanctum of the Hierarchs was used to contain 343 Guilty Spark, which floated motionlessly on its side when in the field.

Forerunner restraints

The Forerunners had a variety of ways of restraining individuals. These included confinement fields, which could incapacitate individuals but also block the movement of entire starships. Constraint fields were a type of less restrictive energy field, which held the captive immobilized in a small bubble. A Forerunner stationary field projector was used by the Covenant to hold Professor Ellen Anders prisoner at the Apex. While limiting overall movement, the device allowed Anders some ability to wiggle within the confines of the field. AI suppressors were Forerunner software used to deactivate ancillas. They could effectively be used to restrain Forerunners who wore personal armor, as the suppressor could lock the armor down and thus completely immobilize the wearer.
