No idea. Probably less than you think. Its probably not a good idea to try and catagorize it that way. I can tell you in 20+ years of service i have come across a grand total of zero chics that have said "i really wish i could be in the infantry". Guess what im trying to say is i dont know where the pressure to lift this ban is coming from. I just dont see or hear the outcry from women to justify even bringing it up.
