I monitor REMCS pretty much on a daily basis for both work and recreation when time allows. I want to say that around the start of October I noticed a change in the unit ID's. They previously had a four digit sequence of numbers to identify ALS/BLS/Rescue depending of which tour was working. Now they keep it simple, "EMS 1 and Mic 1 for the assignment." Haven't heard Rescue in a while but that is because I am told their newer truck, the smaller one they purchased within the past two years (or so?) was involved in an MVA. The supervisors still use 400 series numbers. And yes, they still do dispatch Orange EMS which I believe would be EMS 91 and 92. Hope this helps. If anyone has further, please feel free to correct the above info.
