Usually Hapless usually does Combat Mission videos, but his analysis of how magazine-fed bolt-action rifle influenced war in the run up to WWI had some revelations to me too.
If you don't have the time/desire to watch the entirety of it (I'm only up to 1914 myself), you can watch one video from this here timestamp and then watch the next one on the start of WWI to learn more about the material conditions that made it such a grinding shitshow.
Then we can go back discussing the political-ideological bullshit that put it all in motion
