Tamatha Patterson of Huntingdon, Tenn., during a press briefing at the Pentagon in Arlington, Va., Thursday, Jan. 24, 2013. The decision to lift the ban on women in combat has opened the door for a change in the law that currently compels only men between the ages of 18 and 25 to register for a military draft, according to legal experts and military historians.
