The Attack Dog is the ECA's basic scout and detector unit. It is also capable of attacking enemy infantry.
Trained for its strength, intelligence and obedience, the German Shepherd is a relatively new breed that dates back to the late 19th century. Its traits make it a prime candidate for canine operations alongside police and military units, including those of the ECA. It goes without saying that the Attack Dog is only able to combat a very narrow variety of threats, but it mangles any infantry soldier foolish enough to venture near once it's off the leash and ordered to attack. In addition to that, the dog can detect covert infiltrators and sniff out explosives. Its specially designed tactical vest is also equipped with sensory and a 360 degree camera, making it useful for reconnaissance missions thanks to its agility and good sense of orientation. Finally, the vests can also be upgraded with ceramic armor inlays that provide a high level of protection against small arms.
Barks at enemies to annoy them. (^_^)
