Why is the united states sexest?

we should be aloud to have women in the united states special forces because that doesn't take just physical ability. it takes more mental than anything!. and women are more mental tough than men. but men are stronger. but women or smaller so they would be able to hide they're quieter on foot. and their adrineline exceeds higher than a mans, with self control. it's also scientifically proven that women have better eye sight in the dark and far away distances. these abilities could be helpful on the battle field, but why does the military ignore these things of women. why cant we be in the special forces or operations or front line?
