This is normally an {{Averted}} trope. While the general population tends to think that most people can go through war and come out just fine unless they're 'wimps,' WarIsHell. Most war-based videogame and movie characters are shown to go through things that in real life would leave them completely unable to function, let alone live a normal life. Of course, this is one of those AcceptableBreaksFromReality, since the MainCharacter ending up a gibbering wreck or street person after taking so many hits to their SanityMeter isn't a very happy ending. Almost any character who ''doesn't'' end up at least somewhat traumatized after war or other brutal events counts as an aversion, unless they're a psychopath (or in the lucky minority). See the RealLife section.
