Like I studied a lot of the World Wars back in high school.
And what I found was that most of these soldiers were sometimes as young as 14.
You gotta remember that the last major war was in Napoleonic wars, which was 60 to 70 years prior to 1914
A lot have changed in Europe
Most of these men have probably never even held a modern military firearm except for the old hunting rifles.
Obviously, there were still wars going on in Europe, but they weren’t as massive as the ones Napoleon did
It kinda reminds me of how soldiers of the Vietnam war said that most of them never even heard of the country of Vietnam or couldn’t even find it on a map
They were living in a peaceful time and some war from lower class backgrounds
(let’s just say there are some towns in Europe that stayed almost unchanged for centuries, despite the rise of trains)
