I was headed out as TACFIRE was being fielded and could see exactly what you and your battalion commander observed. I had no idea the TACFIRE required that much ancillary support with its own A/C truck-mounted van. It’s obvious the Army created a monster that would consume the ability to get the job done without massive computing support.
I guess in today’s thinking one would consider the TACFIRE as a server for all the unit’s VFMED and BCS systems at the batteries and the maneuver units’ fire support elements.
