Do you have some kind of an individual Combat Fitness Assessment to be undertaken by all those in an Arms Corps in Finland, Mika? I don't think any military would be caught letting a woman who could not pass the male standard (which should be the single standard) into a Battalion. In some senses I totally agree with you, men and women are not physically equal, not by a long shot when it comes their physiology and composition of testosterone in the body, etc, which I'm led to believe contributes to a large part of the physical disparities between them. But if you take a look at the OP, like Battuta hinted, militaries including my native Australian Defence Force have invested time and money into studying the ability of women to complete things like an Arms Corps CFA and found that there are women who can. They are not numerous, and will never be numerous, until, as I've said umpteen times this thread, we can re-engineer the human body, but they are there.
I have my doubts as to whether they could fill roles in units like yours (I assume it would be the equivalent of our Light Infantry?), but I believe Officers in New Zealand and Canada who've been female have filled billets in Mechanised Infantry units, and the late-Captain Nichola Goddard, whom I like to mention was a Field Artillery Officer, I believe. Dekker's posts were also good reads on women in Combat Engineers.
I think the onus should be on the training structure to ensure that capable women are adequately prepared. Unless we institute more hardcore minimum standards, women are going to need a supplementary training program before the commencement of Infantry specific training and after Basic training because of what we know about the differences between the average male or female when they rock up, and how long it will take a female to reach an acceptable physical standard for the duration of Infantry training.
"Why we should enlist women who with massive amount of training can barely match men with a reasonable amount of training?" Because equality is important, that's why. Anyway, you're seriously underestimating what woman are capable of. Most women don't care about their physical strength as much as men, which leads to less effort and lower ability. A woman who tries hard enough could be stronger than most men.
I think to some extent Mika has a legitimate point. There was an article written by a Marine Corps Infantry Officer (may have been recently retired) that I'm struggling to find that was in favour of women in combat units, but even he conceded that women would be taking the spots of the weaker males in the Platoon. Simply due to the way the female body is, they won't be your superstar soldiers who are running rings around the rest of the Platoon and it does seem counter-intuitive to introduce a whole population to Infantry that will never be able to rise as far as the existing population. But conversely, if a woman
can earn her spot in a combat unit, I believe she should be able to serve in one. Especially if she's taking the place of some dropkick who doesn't want to be there.
Your last point though, I think needs some clarification. Yes, absolutely, men are not stronger than women when you compare the two populations because there
are women who are stronger than some men. Even women who are stronger than a large number of untrained men. But it will in the vast majority of cases take a woman far longer than a comparable man to reach the same levels of physical strength. Just looking at the Olympics at which sports men and women can compete in at the same level, and in things like lifting competitions is a good illustration of just how big the disparity can get. A lot of people don't realise just how physical a job being in an Arms Corps is.
All this aside, there's enough evidence to suggest that women can at least hack the standards in things like the CFA. What I'm more concerned about is what the Marine Corps CPT in the article I've linked in the OP talks about, regarding the price of combat on her body, and whether female soldiers will be able to maintain their fitness in the field as long as men without compromising both their own and their unit's ability to function.
