Well I don't know what kind of euphoria there is in western society about "special forces" and practical perspective of wars
(much) Better training and by far better stock of soldiers to work with, seeing these guys are "handpicked" from the regular troops. It's again this minority of people who can act rationally under extreme stress. Plus of course do exceptionally well in physical and mental tasks soldiers require. In our drafted army which trains majority of the fit male populace, jaegers get adequate training, guerillas pretty good and 2nd line troops such as transportation not so much.
, but you can be sure that being pushed to the end, and fighting back for your own life is a life changing experience, you would see countless of profiles becoming killers in most gruesome way, not because they were "natural born killers" but because of the circumstance they were in, because of self-preservation.
You misunderstand. Some people are just naturally good killers, there is no need to "quote" it. Of course it's not about killing, it's about resistance to stress, lessened self preservation and other qualities. It's also about as unusual as being left-handed, or a boxer who's very difficult to knock out. I do not really mean (only) psychopaths either although they tend to do naturally well in dangerous professions.. It is possible to train people to act in a certain way through rigorous training, just as americans have managed to get majority of infantrymen to use their weapon in anger. Even if you have the nerves, you may just suck at soldiering otherwise too.
