Z-2500 autosentry

The Z-2500 Automated Protection Drone (Z-2500 APD), or Autosentry, is an automated Forerunner combat support drone.

Overview
The Z-2500 is a stationary automated drone that is materialized through hard light from a combat fabricator housed in a user's armor. The drone is composed of an anti-gravity drive located at the lower back, which provides pivoting hover movement in a stationary position, a firing lens located at the very front, and a pair of targeting arrays located at the lower front. It can provide combat support and protection in combat; when it detects a target, it emits a noise and a red light, then fires a bolt of light mass. While its firepower is negligible, it serves as a secondary source of targeting to slowly grate away an enemy's shielding while exposing them to direct fire from another weapon. It currently outstrips similar devices used by the UNSC by virtue of its mobility and power. It is commonly utilized by Promethean Knights, but can be integrated to the MJOLNIR [GEN2] armor, allowing Spartans to provide suppressive fire and open new tactical opportunities.

In War Games, the targeting arrays and firing lens take the color of the team the controller is on. In the field, however, they are light blue. The Z-2500 APD can be fooled by a hologram, and will fire on the hologram. The Z-2500 APD can also be avoided by a completely stationary target using active camouflage. A camouflaged target will be detected and targeted if they are moving however, and activating camouflage when already targeted will not cause the autosentry to lose its lock.
