Does anyone know how the NCSHP numbering system works? I know it is the Troop Number, followed by the district number and two more numbers. such as D4xx is a Troop D district 4 car, but what about special numbers such a D9xx and does the xx have any location meaning or is that just issued at random to each officer? If someone has a list of what each unit is such as Capts, Lt's, Sgt's etc would be helpful.
