Dog

 is a warrior of the Marines.

Background
It costs 750 Resources and one Supplies to train this animal unit at a Dog Kennel. When it comes to patrolling and looking out for invisible enemy bugs, sometimes the best man for the job is an animal. That's why the Marines have been train- ing Dogs. These highly disciplined creatures can smell any attacker within range, and bark to warn others of the hostile presence. If things get serious, Dogs can switch over from bark to bite in a pinch.
