I think that we can look at it with a bit more nuance though. The situation you described - someone having issues with the weekly training - is entirely understandable. And again, I'd argue that if women in combat roles continue to struggle with regular training, or have other issues pop up as time goes on, that is a valid concern. But if you have a woman fresh out of training, having seemingly passed with no issues, and there's nothing else on which you can evaluate her, saying, "Well, I bet she's going to have problems anyway. She probably won't be able to do the job," isn't benefiting anyone.
