Women have been in combat roles for a long, long time.
When German counter-terroism units hunted the Red Army Faction and the Baader Meinhof Gang, (my recollection is) they were told to shoot the women first as they were considered the most dangerous. Also remember that there were several women among the Beslan school hostage crisis terrorists/murders.
On a personal basis, I performed engineering at a major State women's correction center and talked to corrections officers who knew many of the women there were very dangerous and had demonstrated that by their crimes.
Personally, I don't like the idea of a woman in combat, but historically many women have fought in battles and accounted well of themselves. I think it all depends on the woman, her physical strength, her martial skills, her mental attitude, and her motivation.
Because.
The argument that Israeli, Kurdish, and various other nations’ women serve in their infantries, therefore American women can serve in ours, is flawed. The Palestinians have vowed to “wipe Israel off the face of the planet” and are constantly causing riots or staging violent attacks in Israel. Israel’s mere existence is always in jeopardy, and in order to ensure its survival, they rely on conscription. Saddam Hussein conducted mass genocide of the Kurds in a campaign known as Al-Anfal. Kurdish women bore arms during Al-Anfal and have remained a Kurdish Peshmerga infantry unit ever since. In order to preserve their existence, Israelis and Kurds understand that they need manpower, professional training, and constant readiness within their infantry. They train women in their infantry to ensure they do not lose in a war of attrition or face another genocide. Israeli and Kurdish infantry women provide necessary manpower to their mission of survival. Its not about equal opportunity for the Israelis and Kurds, it’s about cultural survival—which is why it works. The all-volunteer U.S. military is not at war to defend the Nation’s existence; on the contrary, it has a surplus of manpower, is downsizing its number of servicemembers, and can afford to be exclusive. Again, there is no need to incorporate women into the infantry.
