Because you say so... no<quoted text>Women have different fitness standards from men, there is no gender equality in the military. If you change combat qualifications to let women in front line troops, that's bad leadership.
Women have already been on the front lines, weapon in hand, fought and died for our country. "The front lines" are a more fluid concept now than it was in earlier wars, in this day and age the front lines can suddenly appear and disappear.
There is no need to change the combat qualifications because of women, the qualifications are indeed changing but because of technology, not because of women.
There is not currently gender equality in the military, that is in the process of changing, regardless of your objections.
