The Patrol Robot is a vigilance drone used by the Rebel Army.
The Patrol Robots are small defense drones used to protect the main facilities of the Rebel Army. They are heavily armored, so their only weak spot is their lens, which they use to fire fast laser beams. They attack the player if they are spotted in their searchlight, in which the light turns red, and signals its assault on the player.
In Metal Slug Defense, the Patrol Robot is a fragile unit that serves as back row support with its powerful laser. Its attack has an annoying stun effect on units hit by it, and despite being listed as having Long range, its laser can nearly reach Very Long range. Its only fallbacks are its relatively slow movement speed as well as low hp.
