Among other things, combat is an athletic event. So, putting aside all the social and sexual aspects of this, if there is one woman in an infantry squad it means that the squad as a whole is short the difference in strength and ability to carry supplies, munitions, etc that a man could carry. It’s not about women lacking the ability to pull the trigger or anything like that. History is chock full of examples depicting women being quite capable of doing so. An example of my point has come to mind. Lets say that as an experiment one NFL team could be be persuaded to always have one woman on the field at all times during every game of a season. How many games would that team win? I suggest that the answer is none. Ok, ok, maybe the Chiefs Would have won two games by now. I’ll concede that, lol :)
It depends on her position. If she was the field goal kicker or punter then there is the possibility that that team will win a few games.
A better test would be five women on one team.
