There's also the relevant details that we don't live at a time in which being extremely muscular and full of aggressiveness (which is what the testosterone policy was meant to cause) makes one a good soldier. Being healthy and able to exert a lot of physical effort is absolutely needed, but beyond that not much is gained.

To put it mildly, no matter how pumped up with hormones one is, one cannot outrun an explosion (much less a thermobaric one), a sniper firing from hundreds of meters away or, for that matter, a drone swarm. For those kinds of challenge other traits are needed.

And these required traits are dismissed as unimportant, just witness all the extremely competent military personal, including medal recipients, who were dismissed or made to "voluntarily" resign due to stuff that had no bearing whatsoever on whether they were good soldiers or not.

Note: I'm not American and, from the perspective of my country's own national interests, which tend to be at odds with the US's more often than not, it's a good thing the US is doing all of this, since it's making itself weaker. But from a personal perspective, that I find it quite sad, I do. I have too many American friends for me not to worry about what this will cause them on the long run.
