Here’s a couple of videos of actual modern combat. I’m linking these because I’m hoping to inject some new information into this debate that is a bit more convincing that “a Pentagon study showed…”
WARNING : This is actual combat. People are trying to kill each other, though no one is seen to die on camera :
For those who didn’t watch part 1 and 2, here’s what you might notice in this video :
a. In this video, combat is like playing Battleship, except the other side doesn’t say “hit” when someone is shot. It’s a lot of flinging thousands of rounds downrange blind. Also sprinting while carrying that ammo. Men - large men, even - do much better at carrying large amounts of ammo and sprinting while carrying heavy loads. This is one reason infantry has a minimum height requirement.
b. Specifically, you might notice that the man with the camera in this video is running low on ammo. What if the squadmate he has as an ammo carrier couldn’t quite carry as much ammo or water? You might also notice they toss some grenades at one point.
This combat video is from a different unit in a different situation : M240B HELMET CAM AMBUSH - YouTube
But it’s the same physical requirement - carrying full load, which includes ammo, water, and body armor and is going to be at least 80 lbs, or ~60% of the body weight of a fit woman or just 30%-40% of the body weight of a large, fit man for miles. It then involves needing to sprint for cover or else you are shot, and then lots more playing Battleship blind with the enemy.
Here’s another one : SPECIAL FORCES HELMET CAM FIREFIGHT | FUNKER530 - YouTube
As a side note, the Rangers are essentially tier 2 special forces. Delta Force is the Army’s version of tier 1. Also you might notice, again, in modern combat it’s about firing semi-blind as much ordnance as possible. In this one they unload M203 grenades and an AT4. Those are both extremely heavy (a large quantity of grenades is). Explosives and rocket propellant are heavy because this is the best chemistry can do. (if you made them lighter either they will be less effective or more likely to explode spontaneously)
Conclusion : Real combat is not a place you want a weak link. And it involves a number of tasks that the optimal person able to do them needs both physical endurance and also high peak strength, simultaneously. For women to reach this level of strength, they’d generally need to be given growth hormone all through puberty (to enlarge their skeleton) and then do a lot of steroids. Neither of which are currently legal and both carry serious medical consequences.
