Are operators any different than the majority? What truly sets them apart from a very experienced man that has been to war and fought?(example would be those fighting in Ukraine today)

I get special forces get all types of various training and fancy equipment, but mentally and physically are they more capable than an infantry soldier who has been to war and seen shit? (Multiple deployments)

I cant see them being that far above anyone else, deep down they are only human. I have seen and met prisoners who have shot multiple people, stabbed people etc.. for many killing is an easy job I've come to notice if the price is right - how would these people fair if given the same training?

I'm genuinely curious on what you guys think.
