We are one liberal democrat admnistration away from the total combat integration of women. It'll probably happen in my life time (I'm 40.)
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.
