Overwatch INC
These are the guys Lone Star Security Services or Knight Errant call when they need some serious supplemental help. Skilled at VIP and group security in a wide variety of settings and scenarios, this corp has built a solid rep by letting others take the credit for their numerous successes, and get a lot of biz from various LEO’s.
They have made paranoia an art form, and recruit heavily from high-end military and intelligence units.
