A little off topic, but straight women, as a rule, make lousy soldiers. Aside from the physical issues, they almost universally have the wrong mindset and emotional makeup for it.
Now, as far as skill based jobs, as you listed above, women do as well as men. No question. A woman can be every bit the dentist or translator that a man is. In my own line of work I learned a lot of technical skills from females. It just seems that lesbian women more often have the right mental wiring to be a soldier than straight ones.
I'm not trying to imply anything beyond that. I certainly don't have anything against women. I'm just saying it like it is, in the interest of the discussion about gays in the military.
