From what I know one of your sub branch's is already struggling, This would just make the situation worse for all of your sub branches as Medical isn't really a extremely large battalion that requires that much. Adding a 3rd sub branch would just kill of your sub branches including the "new one" after a few weeks. And the job you are trying to have that sub branch complete may sound interesting but you only said like 2 things that they did and those would require a fair amount of planning each time. As I see this it would just make things much worse and harder for your command and if you really want something like this to be than take on of your current subbranches and add a specialty inside of it like have people deal with the kind of stuff you brought up and they get to do their own thing over there and the current researchers for example can continue doing what they are doing already. This may be vague as it is weird to explain while not face to face so if you want me to go more in depth message me on discord whenever.
