It seems to make no sense, as the average female is less strong and of different physical and mental make up.

The average female is less strong than the average male but the overlap is such that the best females will be better, in many respects, than the average male. The average male, after all, lies somewhere between an elite fighting machine and a pot-bellied couch potato

I expect that there will always be a lot more men on the front line than women but, for those females who have the desire and measure up to the requirements, why not make use of their talents.
