The matter of fact is that war is messy especially guerrilla warfare which is the only war that basically exists today and in that context what's an acceptable ratio? 0 means surrendering or being stepped on ask Ukraine but is it 1/5, 1/10? Ideally you have zero but to have total disregard of the service members life doesn't cause there to be less war or civilian death. Just more onesided brutal wars. These are hard questions but to paint the people that fight in wars in democratic societies as just souless sellouts is reductive and its the type of thinking that leads to mass murder by political groups. Souless people don't feel PTSD for what they did they are souless. PTSD is incredibly common in the services because we don't want empathless murder machines. Because when it comes to wining wars (wining a political objective ultimately) generally speaking civilian deaths don't help political goals which is what the elected officals ask the miltary to do. But most importantly the elected bodies are the ones asking for invasion.
I think these are hard questions that good solutions from the miltary side of things don't exist but most importantly I really think we as a society need to have more serious talks and rational conceptions of how war and conflict works. I can't recommend On War by Clauswitz enough, but acoup also has a great primer on it [1]
