Physical restraint (Earth-5875)

Physical restraints are technologies devised for maintaining individuals in a helpless state under captivity.

Covenant
The Covenant uses energy shackles to emprision others. For his failure during the Battle of Installation 04, Fleetmaster Thel 'Vadamee was restrained by two energy shackles so he could be branded with the Mark of Shame in October 2552. The Covenant also employs stasis fields, one which was notably used at the Sanctum of the Hierarchs to contain 343 Guilty Spark.
