my wife is in the Army, so I have an interesting take on this subject. My wife believes that women were not meant for combat roles. We had a debate last night on the issue of combat. I was watching the last battalion and she is like "how can you pick a job that deals with that [combat]." Later she said that she could not deal with the stresses of combat and said that women were not meant for such rolls.
I have worked with women in the Army, but not on active duty. I was deployed with the reserves to Iraq as combat bridging. In the 12c mos, women are allowed to serve. We did not have too many problems but there was some problems with relationships and sexual harassment. It is the same way with my wifes unit. My wife has a friend who is trying to sleep with the major to make "life easier in the office." I shutter to think of the problems that would occur if women were allowed in the infantry. My unit is the biggest bunch of bastards I have come accross.
in conclusion, I am for females in the army, but not in direct combat rolls.
