when i was still with the army (mechanized infantry) disliked female soldiers for a couple of reasons...
1) most of them (if not all) did not meet the physical and mental standards put up by our instructors, therefore forcing the rest of us to do their job too, which is fine at times, since being in the military is also about the man (or girl...) next to you, not just yourself...but most of the time they couldnt carry their bags for longer than 20 minutes, meaning some us had to do it for them
2) also, being surrounded only by guys, doing "man stuff" (drinking, gettin ditry, talkin about god knows what...) doesn not leave a lot of room for female soldiers to fit in...
3) also, being away from home and your gf / bitch / staurday night hooker, i found myself lookin at female soldiers in ways i shouldnt according to our instructors, which the females obviously noticed, and what them feel uncomfortable i'd imagine
4) the few female soldiers that really did a good job being a soldier looked like men and behaved like men, they would over-do the whole drill-instructor-boot-up-your-ass to seem as though as they possibly could have....
5) smelling their parfum made my uniform take on a different shape.......
though i agree with braddock about other countries using females as soldiers and doing it successfuly....
