The part you're missing is the investment the country makes into this endeavor so a very few women could achieve their dream. They have to develop and make available gear for women. Then they have to have the separate barracks, showers, etc...Then specialized training for the DS. Then the additional legal costs for the sexual harassment cases that will come up. And the planning for what to do if someone becomes pregnant...does that count as a fail or does she get a do-over?

We have to ask ourselves whether its fair to ask a nation to do all of that so a very few might actually make it. In Canada, I believe combat arms has about 10% women in it. Infantry is probably much less but I could not find any stats on that.

Then we cannot overlook the political pressure over the years that will undoubtedly develop to admit more women. The standards may be at long term risk if not enough women can pass.

I fully realize that there will be some women who will really be awesome at this but I'm not sure if makes economic sense.
