Most of the females I ever encountered in the military were never able to easily pass their PT test even at their standards. There were a few notable exceptions who were excellent runners. I underscore the word few. It was very few. Even then they were lean and with little upper body strength.
Women never seemed to have problems with sit ups.
Who do you want throwing a grenade? You or some 5’2” girl? Maybe she played softball. She probably didn’t.
No matter how hard you train, you can never meet the realities of combat.
The number on the hand grenade used to be that 45% of women couldn’t throw one far enough to place themselves out of the kill zone, and of course that means that almost none of the females could throw them with confidence and accuracy.
I would rather the females just stay away from them.
