A 21-year-old recruit made history Friday the second she completed her enlistment.

Pvt. Julie Corgan became the first woman to join the service as a cannon crewmember after her entrance processing in Jacksonville, Florida. That military occupational specialty, 13B, along with field artillery automated tactical data system specialist (13D) officially opened to female soldiers Oct. 28, granting women access to nearly 20,000 new positions.
