Look at what the Soviets did during WWII. Entire squadrons of bombers and fighters flown by women. Tanks with women crew members, tanks with women commanders, tank battalions with women commanders, women snipers, women field medics in infantry units. Women on artillery crews. When it comes to survival of a nation, there is no second place.
The USA isn't the Soviet Union
Americans are trying to integrate woman into unisex units which will fail. History shows that female warriors do best in all female units and usually as support for men.
But there were no women in the trenches on the western front which is where the women in combat arms will serve. The Soviets were not that stupid.
