Has the Chicago Fire Dept. changed their response plans for working fires and 2-11's? The reason I ask, is that I was listening today to a 2-11 on Halstead (5th Battalion) and there seemed to be more chiefs assigned to functions I've never heard before (safety, staging) and suppression companies bringing their "specialty" equipment, for example on this particular call: a light wagon (at 2pm in the afternoon?), the rehab truck, and 5-1-5 (Special Ops Battalion) was also assigned. I know there are certain chiefs or positions that can more-or-less 'pick and choose' which runs they go on. I listened to this call from the beginning and did not hear any special requests. Thanks for the help!
