OOC: Sorry Jello, forgot something in my attack force: 10 Grutchin Assualt Carriers Each GAC carries approx 50 Grutchins. Grutchins attack enemy ships in a swarm. They have acidic fangs and rear talons that can rip into metal. Grutchins essentially devour metallic objects. They can be killed relatively easily, but they are small, fast, and numerous.
