The K9-Unit spawns an attack dog named Juneau that will hunt down and eliminate enemies with 1 bite. Once active, she will follow the player around and eliminate nearby enemies by default. She can also be put into Patrol mode, which will make the dog protect a certain area of the Player's choosing.
Juneau appears in Nomad's Specialist HQ video. It can be seen chasing members of the Elite Colombian Rapid Deployment Force FUDRA, as well as killing a highly ranked soldier named Mendoza, ultimately avenging the death of Nomad's fallen friends.
