I'm not adverse to women in combat roles, however I'm opposed to any lowering of the standards, for women.
I have a mate who is a former infantryman and he is staunchly opposed to women in the infantry, not because he doesn't think there are women out there who can do it, but because there's significantly more men for every woman who can.
You see the way he explained it was his training you might have 100 male grunts and half would drop out because it was to hard or worse because of injuries and accidents, with women you might have 100 female grunts and only 20 might be physically fit enough to pass and persist with the training.
Now these women would make great soldiers, but it's the other 80 that's the problem. You suddenly have the PR nightmare of a lot of women regularly being injured or heavens forbid killed (it still happens). So everyone in the army doesn't care because they understand how difficult the training is, but the public can't stand the idea of women being hurt (see the whole Jessica Lynch debacle), so they complain and politicians influence the military and the standards get lowered for women. Suddenly you have female soldiers who are not necessarily up to the same grueling level of professionalism as the male soldiers and lives are endangered in an actual warzone.
This isn't exaggeration, in the Australian army women have a maximum weight of gear (hypothetically lets say 90% of normal, not sure the exact figure) they can carry and if there's a bunch of them in a section, the men have to carry the additional weight on top of their already heavier gear. Women usually aren't expected to deal with the MAG58, which weighs nearly 12kilos empty, however in a rifle section every man must be ready to use it if the situation calls for it (gunner's injured or dead).
The way I see is both women and men should be comprehensively tested and examined medically, for both physical and mental condition before being allowed to train or fight in a combat role. If it means 100 men to every one woman so be it.
Also what needs to be dealt with is the philosophy around women, I've heard escapists on this site say things like "women would be good in the army, I'd go out of my way to save a chick", that's WRONG, you should go out of your way to save anyone in your section or platoon, male or female, they're a soldier first and your comrade, before being woman.
