Defense chief Leon Panetta is scrapping the military's ban on women in combat roles. The AP has the early scoop, saying the decision opens up hundreds of thousands of positions in front-line and commando units. Panetta is expected to announce the decision tomorrow, and the military branches have until May 15 to present their plans on how to implement it. Some of the positions could open this year. The branches have until 2016 to make their case that particular posts be off limits.
