Interesting question asked many times through the past with many fierce answers on both sides of the fence. Many, as you see, will find the mere asking of the question inherently sexist. I ask, since when did women stop finding pleasure in just being a woman? Why do so many women so fiercely argue this case, when none are in a combat arms field in the US military, so obviously and indisputably none can argue from a detached, dispassionate and reasonable perspective?
Also, you will always find them boasting this ridiculous wives tale of women being able to withstand a "higher threshold of pain", but there's never any VALID source cited, and any source of that information would be dubious. How is pain measured and why, when I'm in the field with women, is it only them whining? My personal experience; 1 out of 10 soldiers in a unit being female, 2 out of 3 on a "walking PT test" profile are female.
I was told that women marine recruits out shot male recruits on the M16 range. When I experienced differently with pistol and heavy weapons ranges in the field, the story changed to women fire better small caliber rifles. I was eventually never able to find a valid source for any claim of that sort. Also, before I left the USMC, the Commandant at that time, General Al Gray, wanted ALL Marines regardless of MOS or sex to undertake a 26 mile road march annually-I don't think it ever passed-and the one time I did see it happen in a marine unit, most of the female marines weasled their way out of the hike.
So, women in the US military are currently fulfilling roles in OIF and OEF that expose them to combat dangers, and it's not only Rangers and infantryman getting into firefights and ambushes and such. I've seen vets with the new Army combat action badge that probably saw more combat than some combat infantry badge wearing soldiers. But, this isn't the point. One of my points is, if women want to argue so strenuously that they can do the same job (which is neither here nor there to me) they need to put their money where their mouth is and get actively involved in changing policy so women can attend not just airborne or air assault school, but ranger, special forces selection, para-rescue, marine recon, sniper, BUDs/SEALs. Also along this line, it is not my responsibility as a male soldier to stick up for you and tell people you can do it-it's yours. This training needs to be completely unsegregated-they even have to sleep and shower in the exact same facility due to the training and op tempo. And, they need to do this without having a congretional inquiry over the guys "hazing" them differently like the gal at VMI. (Which is another whole argument-that first gal had full blown scholarships to other universities-why did she insist on attending VMI, an up till that time all male military institue). http://edition.cnn.com/US/9709/02/briefs/vmi.cadets/
My personal experience with women in the military; they CAN do what they set their minds to (just like anyone else). Too bad many just want to hook up, get knocked up, and get out. Frontline? They can't even get past a Defense Language Institue language course, an MI course, or a supply or admin course with out having (in my experience) about a 30+% drop rate (eventually) due to getting hurt or pregnant. The attrition rate of men, according to the source I cite (a woman, by the way who offers countless other sources) is lower.
If you're a woman and NOT in the military, don't even respond to this. If you're a woman IN the military, don't retort to this as if it is not fact-why are the physical fitness tests different if you want so much equality? My Army PT 2 mile run for 70% in the 37-41 year old age group is faster than that of an 18 female at 86%!!! Is it because you can't run as fast or do as many push ups or sit ups and female marines can't do pull ups-they get to do a flex arm hang which is (of course) supposedly more difficult? Whatever.
Until I actually see women spend three or so weeks with my group in the field hiking 45 lbs for 26+ miles, no shower, etc., I'll assume they just want TALK about being able to do the same thing I can. Believe in yourself so strongly? Don't talk-talk is cheap. Put your money where your mouth is. Get active in changing (not just griping about) policy and get your butt to the Q-course or the like, then I'll respect you more as a soldier. End of story.
