Are men the more expendable gender?

I am an egalitarian, I believe in true equality between the sexes. I believe both genders should get the same opportunities, I believes both genders should be viewed as equal in the eyes of the law, and I feel of a woman wants to fight for her country she should be allowed to.

Yesterday i got into a debate with someone who for all intents and purposes argued against such an idea claiming that women were too biologically weak, now i'm no fool i know full well the biological differences between men and women. However in his eyes, the gap between men and women were so insurmountable that women shouldn't even bother trying. He would then throw arm grip studies and basically his argument was Testosterone=Strength, Estrogen=Weakness. Both genders should just stick to their proper roles

See here's my issue with this, if what he is saying is true then yes, men are biologically superior to women in terms of strength and combat ability. But it's also a double edged sword. It also means that men are more disposable then women and capable of being replaced due to the fact that women can give birth and men cannot. If this is true then men are expected to fight and if need be die to ensure a woman's safety, it would normalize the mentality that a woman is free to leave a man to die in order to save herself, because that's what he's suppose to do.

If my asking around was suppose to make me accept that men and women can never be true equals it failed, in reality all it's done is make me more pro-gun. So here's the long and short of it, if what these people say is true and biology truly cannot be overcome.

"Women are weaker, but men are expendable" do you agree that this is true?

Personally a world where this mindset is the norm, isn't a world I want to live in. I understand this is a rather loaded question but there's no way to sugarcoat it.
