Hey ButchGone...FITs are the Field Intervention Teams for each zone....if you listen in you can get a pretty quick grasp on what these are for if they are active. OTGs go back to the first trunked system around the time the Olympics were here, they are used for special events (last weekend for a concert security on one of them at a park)...but I think they official name was Olympic Talkgroup or Officer Talkgroup...maybe I can get a verification? But they are always just referred to as OTG 1, 2.....
