A female soldier is expected to join the Army’s elite 75th Ranger Regiment this spring, service officials said, a first as the U.S. military begins to integrate women into its Special Operations forces.

The woman, whose identity was withheld by the Army, became in December the first female soldier to pass the service’s Ranger Assessment and Selection Program (RASP), which is held at Fort Benning, Ga., and designed to weed out soldiers who are not capable of meeting the Ranger regiment’s intense missions and demands.
