Yes all of those units most likely have women assigned to them. But just because you are assigned to a division, doesn't mean you are on the front lines. Hell only a portion of a Division is even deployed at any given time. I can only speak from my experience in the Marines Corp, but it takes roughly 4 support personnel to keep 1 grunt in the field. An old 1st Sergeant I had in NCO school years ago used to put it this way:
For every grunt, there is one person sending him to fight, one person keeping him fed, one person getting him to the fight, and one person keeping him paid to do so.
