They can't run as fast, jump as high, lift as much, or stay unpregnated nearly as well.
When I first came in we had the WACs. That was great and should have stayed that way. No one doubted the contribution of nurses, admin assistants, etc.
What about the other specialties. There's combat, combat support, and combat service support. I generally have no problem with females being throughout combat service support provided they can do their own lifting for any specific job that gets mention.
I belive that Lynch's case is set to be politicized beyond what the poor woman knows at this point.
