I've always been impressed with how DS9 portrayed women in power. Arguably, other Trek series had prominent women, even one character that was the series' lead. Unlike Voyager and Enterprise, DS9 had two women in the top ranks of the station's hierarchy (although it gets blurry when Worf arrives): Kira is the XO, and Dax is arguably the second officer. What's interesting to me is that the stories always put them into the fight, not only pushing buttons to fire phasers against ships, but in the middle of close melees, firing rifles, and in some cases, using their own fists. Of course, DS9 had more of this kind of fighting, and Kira's backstory predisposed the character to react physically to threats. Dax, OTOH, could easily have devolved into a nurturing role. Instead, she was very much the beautiful warrior, different from the Xena-types who would follow. I will give credit to Terry Farrell: she seemed to learn the choreographed fight sequences very well, and she projected a stature to make it feel as if she could perform those actions naturally. By now, it's not unusual to see women fight in films and on TV, but DS9 still seems to stand out because of having two women involved in this way.
