In mixed-sex units, men have to be assigned to assist the women in physically challenging situations, and there are certain jobs that they just can not do. This is just a simple fact. Assigning a task to someone who cannot do it harms the fighting ability of the unit, and that translates directly to casualties.

Don't get me wrong. All women in the military should do all the training, including combat training. People from all branches and types of units have to fight at some time. I have the utmost respect for women who volunteer to serve in the military. But, they should not be assigned to combat arms units as if they can do the job as well as men, when they most certainly cannot.
