I don't know what you're trying to say -- infantry, armor and artillery units are basically all male today, just as they were on D-day. So if we had today's military policies back then I imagine the Normandy invasion would have looked about the same -- maybe with a few female medics, jeep drivers, clerks, etc in the mix. And the outcome would have been the same.
I have no idea what you mean about the Tet Offensive -- in fact we had females in the U. S. military in 1968, mostly in medical units.
I recognize some challenges of women in the military. But I also recognize they've made some heroic sacrifices. The author of this article should be a little more thankful, and a little less snide.
