In the last shot, the woman is on the left. The shot with 'there is one constant' has a female 'marine' looking sideways with a helicopter and the sun behind her. In the snow scene there is a black woman in the background.
Remember, it isn't an army or navy recruitment commercial without the director pretending that at least one woman is a man.
I just watched it again and didn't see a single woman. If they're there the USMC certainly aren't making them very visible, which is good enough.
