Yes, I was describing the Divisional Field Hospital. Based on my little research I was earlier of mind that they do not fit into scale, but as I found out there was a Field Hospital element responsible for surgery that was set up closer to front lines, that would be the Field Hospital element that could be modeled. 50 beds and all that.
The difference bw Main Dressing Station and Field Hospital was that while the former was larger and better equipped than Dressing Station, they still lacked the facilities for the more demanding surgical operations a Field Hospital (/A) had.
My little research was done on one country only, but what you summarised would be a very good abstraction of how to add medical logistics to JTCS engine. I would only add Medical Platoons too, for those designers who would like to stick to platoonsized units.
So, instead of Medics I personally would prefer Medical Squad (SP2) and Medical Platoon (SP6), which otherwise would be similar as far as their capabilities would be considered. Then, designer could choose whether to place one Medical Pltn per Bn or Sqd per Coy.
Now, if Stefan would experiment this with CWE, I would be very keen to see how these are implemented into platoonXX.oob files
