This decision will not only lead to the deaths of more women, but more men as well.
It is a well understood military concept that soldiers are strong because they can depend on the men standing next to them. Diminish that, and you diminish the success and survival chances of everyone in the unit.
I will no longer advocate a career in the military to any of my students, nor will I allow any of my children to serve. I will not have them die for some liberal a-hole's social experiment.
