I view combat roles in three areas, logistics (separate supply chain with female specific items/drugs/habitation/pregnancy status), unit cohesion (issues with males and females in combat areas), and mission capability (durability, ability to perform a job, whether manually hauling things or fighting hand to hand in a foxhole), and women simply don't add anything to the equations.
To the point-the military, from an operational and logistical perspective deals with "Average capabilities and supply needs" in everything from operational capability to boot sizes and underwear dropped into a long term combat zone where resupply is in question or limited.
In my view, these don't matter as much in a push-button war, but if we ever get into a conflict where we don't have a push button war and our logistic train is not secure (we do not control the air and/or sea) and could be cut off, the logistics come into play. Birth control would be unavailable, female products might become unavailable, and evacuation of pregnant females might not be possible. Imagine our Marines on Guadalcanal in WWII or the Chosin Reservoir in Korea.
This is not my view because I do not respect females-I wholly do, and have worked in the civilian world under females that I respect as much as any male. Or more so. I feel this way because of the reality of combat, and combat veterans I have discussed this with universally feel the same way-when the fastest male can run a marathon ten minutes faster than the fastest female can, or a 150 lb female stands zero chance in a boxing ring with a 150 lb male, that tells you something.
I adopt this stance not out of disrespect for females, but in total respect of what the combat role physically requires. I believe we do men in combat a disservice by forcing women to serve in combat roles. I believe that social experiment is a formula for failure, and it will be a failure we will pay for in blood, loss of battles, and losses of wars if we persist in trying to go down that path.
Our Soldiers, Sailors, Marines, and Airmen in combat should have absolutely every single factor weighted in their favor for success and survival in combat situations. If we diminish that by even the smallest degree because it is politically advantageous to do so, I think that is criminal.
And I fully concede that their inability to recruit males who see this dynamic with clear eyes is going to provide believers in sexually integrated combat units with the justification they search for.
Regardless of the justification, I believe the end result is the same. I have fully accepted that society makes this choice for roles such as Police and Fire departments, and our civilian population seems willing to sacrifice this reduction in capability that the video you referenced (the four female police trying to arrest the guy) demonstrates, but I refuse to willingly go along with it in the military.
That said, go it will, whether I agree or not with it.
