In 2013 Leon Panetta removed the U.S. military's ban on women serving in combat, overturning a 1994 rule prohibiting women from being assigned to smaller ground combat units. Panetta's decision gave the U.S. military services until January 2016 to seek special exceptions if they believed any positions must remain closed to women. The services had until May 2013 to draw up a plan for opening all units to women and until the end of 2015 to actually implement it.[55][56] In December 2015, Defense Secretary Ash Carter stated that starting in 2016 all combat jobs would open to women.[16]
