- War is for men so weapon should not be made lighter or use a lighter cartridge just so female soldiers can handle them -
I'd disagree. Many countries have females as a part of their infantry (such as Israel). Plus, if it comes down to defending your country and you run out of men, I'd want a weapon that females could be comfortable using.
And the lighter the weapon, the better as long as recoil is manageable. We carry far more gear than we used to, and that means a soldier carries a lot more weight now than they did before.
Assault rifles are also an interesting weapon because of their unavailability to civilians, atleast assault rifles in their truest forms.
They are in the USA, at least most states. Be prepared to pay $7,000 or more. Probably closer to $12,000.
