Women in Combat: A Question of Standards by Jude Eden
The author knows what she is talking about, and isn't afraid to speak it. It explains why women should not be in any combat units, and does it brilliantly and to the point.
It is interesting that the article has been largely scrubbed from the Internet over the years. I am sure the military found it inconvenient to say the least, and Google is all too happy to bury it or remove it from search engine results unless you know exactly how to search for it.
This article is the best ever written on the subject.
My mistake...the article was written in 2015, but references studies done in the 1990s...
That article you linked, really details how hard it is on women’s bodies, to keep up with males in Military (combat) levels of physical fitness.
A lot of injuries are inflicted.
It is probably even more taboo to consider how the emotional or psychological reactions to actual combat (killing and witnessing) will differ between the sexes.
