Try forty-two days in the bush. A shower was clean fatigues every third resupply, maybe.
Everyone came off of that with rashes, boils and other skin problems. Get dusted off for a boil? Not likely.
I can’t imagine a woman physically standing up to that wear and tear.
But every war is different and maybe these sorts of conditions won’t be encountered in the future.
Obviously women usually aren’t as strong as most guys - plus the sexual attractions, etc. I don’t think it’s a good idea.
However - I’m relating this in defense of our young neighbor - a female medic. She had been in Iraq early on and was a medic on a base. Treating mostly locals. She requested to be out with our guys so she could help them instead. She finally prevailed. Although I think the main reason she went out with them was so she could treat the women in the villages - “winning the hearts and minds” thing. But also taking care of her guys.
But - she must have been good out in the field, she did two or three more tours, and always was out on patrols and requested by many.
I recall her mom asking her if she was ever in any fighting.
“Mom - I’m okay.”
“But do you ever come under attack??”
“Um - we’re in Afghanistan.”
ROFL!!! Not bloody likely ...
Roman legionaries faced those problems.
Greek hoplites faced those problems.
The foot soldiers of Sargon the Great faced those problems.
