You've never served in the infantry have you? There are individuals of all different sized, shapes, and characters in the infantry. Ultimately it's not about coarse hairy goons at all.
Unfortunately we're not talking about unarmed combat in a stadium. The M16A3 is a great equalizer even in the most fragile of hands.
I wouldn't rush to chastise someone about babbling given your priors here.
I know some women who could do that. I know some men who could not. What's your point? Not every soldier can qualify to be a Ranger, airborne, of hang in the light infantry. But they could potentially serve in a mechanized infantry unit.
I know women who could do this and men who could not. You're not helping your argument here.
Well, well, for someone so knowledgeable of the infantry, you certainly don;t seem to know much about how or why they are used.
Having served in Airborne, light, Ranger, and mechanized infantry units, I will tell you that infantrymen in all of them require intense physicality to gain and maintain an edge in combat.
Where do we use mechanized infantry?
Well, there is certainly Korea. Whose masive mountains require infantrymen, wearing the same combat gear, to scale the mountains either in conjunction with fire from the armored assets, or to pass assets through the mountain passes to attack the enemies main forces. Does climbing mountains qualify as physical? Does the armor in support make it easier?
There is also the reality of the other extreme, open desert. Nobody walked to Baghdad or Kabul, but when the battle starts, and especially in the close quarters of Urban Combat, the battles range intense and physical. And M-4 might be a great equalizer, but you have to bring it to bear in a manner that takes advantage of your enemies positioning. You must be able to reposition faster and more effectively then your enemy, and the sheer environment of passing between floors, pushing through barricades and often hand to hand combat that result, regardless of how you were delivered to battle (Airborne, Air Assault, or Mechanized) the reality is often the same.
Not too mention, having seen a few destroyed armored vehicles, are women going to be able to reach in and carry out a an injured comrade from a turret?
That still does not address the sexual competition between the sexes. If you think that levels of discipline between infantry units and logistics units are the same you are flat out wrong. It will also not prevent the inevitable gambit from emerging, "If Johnny goes through the door first, I'll get Suzie," and when such acts become obvious they will rip a unit apart.
This is not about societal equity, this is about winning battles. Sometimes a same sex environment is necessary to help ensure that reality.
