Even the people who lived through actual battles (where technology and tactics would be relevant) tend to tell stories that are mostly about hunger, deprivation and being cold. Shooting people and executing strategic plans hardly ever figure in them.

And this makes sense: most soldiers spend most of their time waiting around for battles or marching from one battle to the next. The actual battles themselves take up very little of their time (even if they're extremely stressful).

The stories of those that lived through wars as civilians (the vast majority of people) of course never talk about technology and tactics as they had nothing to do with them.
