[@mdk] Thank you for your kind words.

The Brigade are not a canon faction; They're a hanger on from roleplay lore and Andrei was based off their leader. I just failed to flesh them out in the course of the story. I didn't touch any canon characters and such because I simply don't think I could do Valves work justice; Part of the reason I elected to make Barney's only interaction with the Sectoral entirely off screen.
