A lot depends on the kind of war you go to, how your experience was, and how it ends for your side.

You might have a nice, successful, short war that gets praise from your nation, and that puts the glaze on the six months of boredom and crappy living conditions you put up with before the actual fighting. (Gulf War)

Or you may do multiple deployments to the same environment in conditions ranging from very quite drab to ridiculously plush, yet come away from it with less sense of satisfaction, because the "combat" was endless patrols for nothing, the occasional IED, the occasional death, and no real closure because there was neither victory nor defeat. (Iraq War)

OR you could be stuck in a grinding fight with barely any support, your days spent freezing or baking in a filthy trench as the finest weapons of science try to murder you in new & interesting ways, and death, mutilation, or capture is always just around the corner. (WW1, Korean War, Iran-Iraq War, Ukraine War) Your whole objective is to survive, not enjoy it or hate it.
