Ive only just started playing the game and due to my profession (paramedic) the trauma damage system just seemed a lot more basic compared to hunger/thirst etc. Most likely this will be fleshed out. I'd love to see about 4 levels of treatment improvised, basic, intermediate and advanced. Gun battles definitely should have the potential aggressor think, he may win the fight but will it ultimately cost him his life? in work on my phone but some suggestions i have are different level of splints to make a person mobile, use morphine as a means to increase mobility and stop crying out in pain, not be a magic your healed! For penetrating wounds you could add possibility of a pneumothorax which would cause increased work of breathing, which you really will hear, decrease mobility and also cause decreased field of view (decreased levels of consciousness makes it hard to concentrate on things around you). I will try to write a more detailed response once i get home.
