I believe they have a process with two cycles. Those who don’t make it through on the first cycle can do the test again and if they pass can move on to the next step. Of the people who applied (off the top of my head) 20 men and 2 women failed the first cycle then 7 men and both women passed the second cycle.
From my distant impression of the people who make it into those elite units, once you have the physical attributes it’s really the determination and mindset that gets you through so not surprised that some women are capable of passing through the selection process. Do you even watch UFC bro!? And those are 145 pound women. Scale that up to 170-200 and athletic women could for sure ace the physical portion.
But my point was that some genetically female people will use testosterone and other hormones as a method for increasing musculoskeletal strength/development (among other things) so with the military’s expanded attitude towards applicants, hopefully we’ll start seeing a wider acceptance of the gender spectrum throughout. And If it’s accepted, especially in a place that lionises the military as much as the USA does, it should have a positive impact on the issue across the board.
