At Strategy Page, a look at the political desire to fully integrate women into the combat arms:
In 2014, after years of trying to justify allowing women into the infantry, artillery and armor and special operations forces, the U.S. government decided to just order the military to make it happen and do so without degrading the capabilities of these units. While the army was inclined the just say yes, find out what quotas the politicians wanted and go through the motions, others refused to play along. SOCOM (Special Operations Command) and the marines pointed out that the research does not support the political demands and that actually implementing the quotas could get people killed while degrading the effectiveness of the units involved. This is yet another reason why many politicians do not like the marines and are uneasy about SOCOM.
But action had to be taken and orders were orders. The various services opened up some infantry training programs to women and have discovered two things. First (over 90 percent) of women did not want to serve in any combat unit, especially the infantry. Those women (almost all of them officers) who tried out discovered what female athletes and epidemiologists (doctors who study medical statistics) have long known; women are ten times more likely (than men) to suffer bone injuries and nearly as likely to suffer muscular injuries while engaged in stressful sports (like basketball) or infantry operations. Mental stress is another issue and most women who volunteered to try infantry training dropped out within days because of the combination of mental and physical stress. Proponents of women in combat (none of them combat veterans) dismiss these issues as minor and easily fixed, but offer no tangible or proven solutions.
Back in 2012 the U.S. Army and Marine Corps were ordered to come up with procedures to select women capable of handling infantry and special operations assignments and then recruit some women for these jobs. This had become an obsession with many politicians. None of these proponents of women in the infantry have ever served in the infantry, but they understood that if they proceeded without proof that women could handle the job, that decision could mean getting a lot of American soldiers and marines killed. The politicians also knew that if it came to that, the military could be blamed for not implementing the new policy correctly.
So far the tests, overseen by monitors reporting back to civilian officials in Congress and the White House, have failed to find the needed proof that women can handle infantry combat. The main problem the military has is their inability to make these politicians understand how combat operations actually work and what role sheer muscle plays in success, or simply survival. But many politicians have become obsessed with the idea that women should serve in the infantry and are ignoring the evidence.
