So females in the army fail physical tests disproportionately for males. I hope we didn’t pay any money for a study to determine this. Changing the requirements by sex will certainly not help the readiness of the military. Maybe this is why they are allowing transgenders and so they can get so-called females with male DNA to do better on these tests. We in the USA are in a world of trouble
Weak Link by Brian Mitchell, great read. Old book but documents well the problem.
Making battle-field litter-carry a four-person task, not a two-person task (two women can’t lift a warrior on a stretcher and carry him off).
Reducing the charge in grenades because most women couldn’t throw a grenade beyond its blast radius.
Many other examples in the book.
