Sentry Drone

Sentry Drones are a type of Decepticlone from the Armada portion of the Unicron Trilogy continuity family.

What it sees, Lo Pan knows

Sentry Drones have very little combat ability, but they're not really meant for combat. They are deployed into the field, typically in mazelike areas with low visibility, to watch out for invading Autobots. Once they spot an intruder, they launch a flare high into the sky, signalling nearby Decepticlone units to come in and take care of the problem, usually in the form of a Dropship. Once this has been done, they will fly off in order to alert any nearby Decepticlone patrols. As such, Sentry Drones are best taken out from afar, or with a surprise attack at close-range; firing on a Sentry Drone and missing will still cause it to launch its signal flare. Sentry Drones remain static, though only for a few seconds, as they prepare to fire their flare; they can still be taken out during this time.

Poke out the eye in the sky

Sentry Drones tend to run once they've released their signal flare. If cornered, they have a light laser blaster to keep their pursuers occupied. They cannot fly at high altitudes, so their escape options are fairly limited. The sentry drones are only encountered in two levels: Antartica and the Starship (Before it crash lands, of course). In the Starship level, Sentry Drones retain most of their usual skills, except for the fact that instead of firing a flare, they send off a loud (And extremely annoying) alarm, which draws any nearby Decepticlone patrols to your location. However, these alarms can be deactivated by simply destroying every Sentry Drone that saw you. Transformers
