That problem is easily solved sire. Jes get yerself a battalion of old nags who are post menopausal and then ya don;t have to worry none about dat! They might be tad old, kinda testy but heh, its another body.
Iffen dey is so dumb as to want to go out get caught in ambushes with AK47s turned loose on them form multi-directions or have booby traps and and a bunch of now unidentifiable ragheads to choose from as to who is a combatant and who isn't, I would say let them except for one thing: they are now a menace and liability to the rest of the team.
I know what its like to carry a combat Marine out of a fire fight. Its no place for a female even if they change their name to George..
