there's that one lady historian on youtube who does a bunch of commentary on historically accurate armor, and among the idiocy of "boob armor" that you commonly see in movies, games, and TV, it's very rare for a woman even of the stature of brienne of tarth to wield a longsword or broadsword. it comes down to muscle mass and bone density.

on her videos, she's a pretty average woman, and she comments how most women would not be able to competitively wield even a short sword, because most opponents would be men, and obliterate a woman with a short sword. and when it comes to longswords and broadswords, the body size necessary is significantly greater, even some men can't properly wield them properly. with other sword types, like the falchion, scimitar, or khopesh, the heavy weight at the tip was a major part of the mechanics, and again, a larger man wielding them was like cheating. the small catlike assassin woman trope you see in movies is just fantasy.

society wouldn't bother wasting the resources to train someone unless they were in the top few percentiles of possible success, or literal royalty.

and we're not talking about art or larping. in the historical context, people who weren't "the best" were literally skewered to death on the battlefield. and even some people who were still amazing were still murdered ruthlessly.

oh, and a single man can repopulate an entire country. women were not sent off to war because sheer babymaking math. men are relatively disposable. women are not. whichever sex of the species has the longer reproductive cycle MUST be protected, or your tribe goes extinct.
