But yes, in modern warfare there are as many jobs if not more that require precision or some level of intelligence as those that require brute strength. Even if fewer of them are right at the front line, they’re just as important.
You don’t send a large percentage of women to the front line in wars of attrition because their deaths mean a greater loss of future reproductive capacity than men’s do. But the way countries like the US have waged war over the last 75 years (with a relatively small surface area of soldiers put directly at risk), that’s less of a consideration. The counterpoint might be a border war without massive air superiority on either side like the current one in Ukraine.
