I have taught FAST team operation over the years. I hear what you say that the Deputy never transmitted the 10-66. FAST Operations are sometimes more complicated then appears at first. Therefore, I am great believer in calling all the help you may need BEFORE you need it. I know I'm playing Monday morning Quarterback, but I have seen fires and rescue operations go downhill really fast. Chief's If you have no reserve units standing next to you and something goes wrong, it will be long time before the additional help get dispatched and is on the scene ready to operate.
