Yes, and they should be integrated with the males
Yes, but keep their units seperate from male units
No, but women should be given some basic infantry skills beyond basic training
No, women should never serve in a role where they may encounter combat
When I was at recruit training in Great Lakes, one of the bitch petty officer cooks started writing recruits up for using the time honored phrase "make a hole" when trying to move carts of food or dishes or whatever through the lines of men waiting to be fed.
Suddenly, because this ugly over-sensitive broad got a bug up her ass, it became a crime to use that phrase, and orders came out to use some other phrase, I forget what, to avoid insulting the dried up hag.
The bitches intrude on the men's culture, then insist the men have to change their ways because they find the work environment "uncomfortable". Well, the reality is that no one asked them in, they don't have to be in that field if they really don't like it, and there's no valid reason anyone should change to make them comfy. What the women do when they intrude is plain wrong, and their as bad and offensive as the Mexicans who demand we "Dial 1 For English".
Therefore, the impact of 108 pregnancies to that unit would be 19%, not 2%, and the impact of the pregnancy on the males of the unit was 0%.
Now, I just assumed the number of females was 10%, if the number was smaller, more than 20% of the females in the unit were disabled.
However, since the highest standards should be applied to ensure the best candidates are chosen, naturally the military would tend to de-select females for combat roles, and naturally the women will immediately file a sexual discrimination lawsuit in the nearest federal court. So naturally, the presence of females in uniform implies a distinct lowering of standards.
