Sentinels

Summary
The Sentinels are the guardians of the Halos, and can be controlled by the Monitor of the Installation.

They are hovering robots equiped with an energy weapon called a Sentinel Beam. These beams are used to control The Flood, however they can only manage them for short periods. In Halo 2, after a Sentinel is destroyed, these beams can be picked up and wielded by a foot soldier.

When not engaged in combat, they contract into smaller forms, concealing their weaponry. In later levels of Halo 1 and Halo 2, some sentinels are equipped with energy shields, though all sentinels are easily destroyed by plasma weapons.
