I respectfully disagree. When men fought with rocks and swords, muscles won wars. When men began technological evolution of weaponry, the battlefield began to level. The cannon requires very little muscle to kill the enemy and has been effectively wielded by women. The rifle requires no muscle. The airplane with fly-by-wire controls requires the same amount of muscle regardless of g-force. Women make excellent snipers and man the nuclear button alongside men.
Being a sniper is much more than marksmanship. A woman is lessor qualified than a man after several days of remaining motionless by clandestine camouflage in the field without attracting wildlife by scent.
There are physical and responsive differences between men and women.
