The Bio-Armor can be played as an agent with the sheet. Generic is the class - basically the armour doesn't fit with Marine, Infiltrator, etc so it's a generic and can use devices and skills for listed as Generic. It can technically make use of the Bio-Armor Power Armor which you could justify as the Gigantic Bio-Armor unit (if you know the source).
I received the 5th Column expansion as part of the Kickstarter Moon Pledge. In the package there are 2 Bio Armor Power figures along with 2 bio armor sheets. There is also an Agent Bio-Armor Generic sheet. What is the Agent Bio-Armor Generic sheet used for? Can the Bio-Armor be used as a normal agent? What is the generic agent class? Is that a class that doesn't have any specific skills or weapons. There wasn't any descriptive information in the Moon Pledge that described this.
