I've certainly heard that claim manu times, but never seen it backed up with actual data or even reputable anecdotes. Can you share the sources that led you to this conclusion?
Obviously men are stronger than women and so different standards are reasonable, yet this is also the exact same reason (well, one amongst many) that militaries traditionally did not permit women to participate in direct combat operation. A unit is only as strong as its weakest link.
The US military is now moving towards gender-neutral standards, but that will take one of two forms. If standards are maintained then it will be an implicit ban on women from the most physically intensive roles, or it will be lowered standards for everybody.

You do know there were exams leaked to a group right?
It's like some people really want to feel angry and accept the most vague or fabricated statements as real facts.
But anytime you sit down and try to go the root of the issue in good faith you realize they really was nothing. Best you can find is someone on Twitter that said something stupid and then they use it as if that means there's a whole apparatus enforcing national wide policy based on that person's tweet.
