The Autosentry (UNSC Z-classification: Z-2500 Automated Protection Drone, Z-2500 APD) is an automated Forerunner combat support drone.[2]


Design details[edit]

The Z-2500 is a stationary automated drone that is materialized through hard light from a combat fabricator housed in a user's armor.[1][2] 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.[2] 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.[1][3] 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.[1] It currently outstrips similar devices used by the United Nations Space Command by virtue of its mobility and power.[4] 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.[2]

In War Games simulations, 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.[3]
