I first saw it very early (about 1970), and didn't see it again (as far as I know) until just a few years ago, but somehow the general idea of it always stayed with me. There have been many movies, I think, about women guerrilla fighters, but as far as I know, they usually do it for patriotic reasons. These women were doing it partly to stay alive and partly to get even, which gave it a different "feel", along with the fact that they were NURSES turned guerrilla fighters. Because of this, in the back of my mind, I always think of it as an exploitation film (the kind about "girl gangs" and so on). Which are fine with me, but it isn't one. It also isn't a "yellow peril" story, or really any kind of propaganda film (for France or any other country being in Vietnam). And where else can you see Nancy Kulp (Miss Hathaway) holding a hand grenade? (Unless maybe in some broad comedy routine.) And in how many other films (until a few years later) would you see a nun firing a machine gun? (Even though she did it very briefly.) And I know that people either laugh or get mad when they see an Asian (or in this case Eurasian) character played by a Western actor, but Neville Brand was very good in the part (again, he wasn't a "yellow peril" villain and nothing else). It isn't a perfect movie, but I think it mainly works.
