This particular Signals vehicle is probably the smallest wheeled vehicle used by the Corps with just a crew of four making up the personnel: Wireless Operator, Cypher Clerk, Driver and Co-Driver, which makes it an ideal candidate to better understand how the crew was put together and how it actually functioned.
What I would like to better understand, is whether or not these four positions would actually be filled by specifically trained individuals for each position, or would the crew have been fully inter trained? My civilian gut tells me if all four crew were fully cross trained, it would be the best way to man the vehicle. Any one of the crew could drive as needed, operate the wireless, or perform the code work. You would get the best possible shift rotations and be at a minimum of risk with potential illnesses, or injuries within the crew.
I could be wrong, but it is my understanding the crew would all be RCCS personnel who are seconded to 'XYZ Regiment' to perform that Regiments communication functions.
I would assume that whatever the structure of the crew for this size of vehicle, would just be increased in required numbers for larger vehicles like a Command Low Power, or Command High Power.
If the crew positions were filled by specifically trained personnel, I have a bit of trouble wondering what the driver and co-driver would be doing if the Wireless truck was set up in one fixed location for an extended period of time.
Experts…I await your enlightenment.
