I agree with the previous post in regards to the military having a certain amount of chauvinistic tendencies. It may be more emotionally difficult for a woman to be in the military for the simple fact that it is male dominated. Many women may see this more as a challenge than a deterrent.
I'll come at this from a slightly different perspective, since your post may simply be asking for reasons why a female would not want to enlist.
In the Iraq War, for example, female soldiers have experienced much higher rates of sexual assault than in the civilian population in the US. Wherever they are stationed, they tend to experience more sexual harassment in the military than in regular because the military contains a certain amount of "machismo/chauvinism" that both unofficially encourages such behavior and then does nothing to punish it when revealed.
Unless a person is preapred for that possibility, however unjust it may be, I would avoid military service as a woman.
As the first post very correctly points out, the main reason to keep women out of the armed forces completely (as opposed to the way the US tries only to keep them out of combat) is cultural. However, within what seems cultural, there is also at least some amount of a more objective reason:
- Given that the vast majority of people are heterosexual there is more of a potential for disruptions due to romantic/sexual relations if women are in the armed services. This is more important than in other professions because it's more important to have a cohesive unit in the army than at the grocery store, I would think.
In response to one other point from the first post, even the idea of keeping women out of combat is increasingly cultural. Physical strength is indeed important, but
- The US armed services, at least, do not allow women in combat positions regardless of whether they can prove sufficient physical strength.
- Many combat positions no longer require as much physical strength as was required in years past (helicopter pilot, tank crew, etc).
This might prove to be a fairly sensitive issue. In laying out the potential reasons why women should not join the armed forces, it should be noted that men and women actively serve in the United States armed forces and have been doing so for some time now. The reality is that there are nations where women do not serve and this might reflect cultural values. However, one reason that opponents of women serving use is the idea that women and men do not have the same capacity for serving in combat forces. Physiologically speaking, these individuals point to the fact that a woman's body is not able to endure the hazards of combat in comparison to a men's. The level of strength and endurance needed is more suited to a man's physical disposition than a woman's. This would be one area towards which proponents of women not serving in the armed forces point.
