Hey all, I was having trouble locating a list of OS protocols; I eventually found some separated into three webpages. I thought I would post it here so people would have a single reference. Enjoy.

Data sourced from zilliongamer.com. Stats shown are base level and scale with upgrades. There are 3 categories (Firepower, Toughness, Engineering) and 4 rarities (High-End, Superior, Specialized, Standard).
