My view they volunteered and soldiering (whichever branch) is their profession and they took with that the risks of that profession, with modern equipment and advanced medical care their odds of dying are low in the main but disability is not. But in return we as a society should be sure they are cycled out of combat enough and have the needed mental health and other support to not break them and take care of their families with good pay and benefits. Sending soldier back to war over and over is cruel and a waste of manpower as they lose their ability to function in some cases,
But we refuse to take care of those that defend us by using them wisely and for proper reasons for me that is self-defense of the nations soil, protecting citizens abroad and humanitarian missions to nations after natural calamities if they ask us.
