Combat Knitters

This article (Washington Post, you may need BugMeNot to see it) about deployed knitters in Afghanistan was kind of cool, but it was very clear that the Combat Knitters are *women* of various ages and specialties. Which struck me as statistically unlikely - there must be way more men than women deployed in Afghanistan, and I know about as many men who knit as women. So are men in the military too anxious about their machismo to admit to the WAPost that they knit? (Or maybe the knitters I know are really un-representative of the greater knitting public?)
