Hello...
I completely agree. I'm not interested in change for the sake of change. It should 'fix a problem' or add a feature or function that is currently not available. I don't know about anyone else, but I'm not interested in the number of mobile kitchens or bakeries in a unit. Not to be morbid, but I'm also not interested in field hospitals and so on (sorry M.A.S.H. fans)!
Only those aspects of weapons or activities that enable effects as a result of combat are necessary additions, in my opinion. Accuracy of weapons abilities and limitations is the first thing in my book. Next the ability of units to act together as an organized force. Then the supply level that allows them to operate in the field.
