For the first time ever, the US Marine Corps is allowing women to train as infantry combat officers. It's a move that could open the door for women to fight on the front lines.

Not everyone is on board with this move. One Marine Corps captain warns that women are too weak for the battlefield and putting them on the front lines could damage our military. And, she's a woman, who served in combat in both Afghanistan and Iraq.

This morning on "Early Start," Captain Katie Petronio talks with Ashleigh Banfield about her experience on the battlefield and why she doesn't think women should be in the infantry.
