Women are

great fighters, especially pilots. Because women are smaller and have a shorter center of gravity, they can withstand the G forces better than any man. Even a Arnold Schwarznegger. They are physically better in that respect. They are also better when it comes to run large distances, their methabolic rate is better than most men. They might not be as strong to carry 100 pounds of equipment, but if you need to cover lots of ground fast, their are superior.
And as the WWII has shown us, russian women were formidable oponents in battle. The russians had a few all women fighter squadrons, that raked quite a lot of kills. They were also great tank crews.
But what we have is a cultural shock. The russian system viewed all individuals as equals, despite of gender. The west does not.
We are still hung up on the lady in distress kind of thing. We still view them as fragile little things, that we must protect at all cost.
I suppose women could be kept out of infantry duty, but anything else is perfectly within their reach. You don´t need to bench 200 kilos to drive a tank or fly a plane.
Actually, i wouldn´t mind seeing all airplanes flown by women. We would get a lot less friendly fire incidents and civilian casualties with them "driving". They are much more carefull and methodical, men are way too instinctive and careless.
