Vermins

The 7th legion's vermin drones. Very heavily mass produced. Cheap. Armored enough to survive a couple of shots from any form of point defense (2-3 impacts) if facing impact. Packing high penetration messon projectors.

The Vermins can be controlled by either:
1) No communication, coded protocols and attack targets. Commands are always face targets, keep wide formation, attack turrets/modules.
2) Ship psychic network: Controlled in a very precise manner, used tactically. 
3) Fighter psychic network: Controlled in a fair manner, used as support.
