KABUL, Afghanistan – The Afghan army is training female special forces to take part in night raids against insurgents, breaking new ground in an ultraconservative society and filling a vacuum left by departing international forces.

"If men can carry out this duty why not women?" asks Lena Abdali, a 23-year-old Afghan soldier who was one of the first women to join one of the special units in 2011.

Night raids have long been a divisive issue between Afghan President Hamid Karzai, who doesn't want foreign troops entering Afghan homes, and the U.S.-led coalition that says the raids are essential to capturing Taliban commanders.
