Strategy Page has the details:
Earlier this year, the U.S. Army Special Forces began recruiting women for the first time. The women were needed for “Cultural Support Teams” (CST) for use in Afghanistan. There, it has been found that, if you send in female troops to an area, you are much more likely to get useful information from Afghan women. This was a technique that was developed, and worked, in Iraq. The U.S. Marine Corps pioneered the use of these all-woman CSTs.
The Special Forces does it differently, by using the same selection and training routines (in abbreviated format) for the women as they do for the men. Thus the Special Forces Assessment for CST volunteers is nine days, rather than 24 for the men. About half the volunteers do not pass this, a bit higher than the third of male volunteers who don’t make it. That’s probably because Special Forces recruits mostly infantry and other troops in combat jobs (where there is constant training to prepare you for the stress and physical demands of combat). The year-long Special Forces basic training has been cut to six weeks for CST members. That’s because the women are not expected to do a lot of the training and combat operations the male operators must be prepared for. For the women, selection is mainly concerned with intelligence and adaptability. The CSTs, after all, specialize in intelligence work and forming relationships with Afghan women. But the women do get a lot of weapons and special skill (like roping down from a helicopter) training during those six weeks.
So far this year, 30 CST operators have been sent to Afghanistan and their performance has been outstanding. Special Forces commanders want more CST troops, and want them fast. As word gets around about the success of the program, more women will volunteer. The actual work of each team (of 3-6 women, attacked to a twelve man ODA or “A Team”) is providing health care to women and children, collecting intelligence and participating in raids (where they can more easily search women for weapons and other contraband).
