While assigned to Aberdeen, she served as the chief nurse of general medicine at the Kirk U.S. Army Health Clinic.
In addition to Maryland and Iraq, Ortiz had been stationed in Puerto Rico, South Korea and Walter Reed Army Medical Center in Washington over her nearly 16 years in the service.
She was identified by the Defense Department as coming from Bayamon, P.R. But records kept by Aberdeen Proving Ground indicated that Ortiz was born in Pennsauken and has family there, a military spokeswoman said.
Ortiz enlisted in 1991 at age 24 and received her nursing degree in 1999 from the University of Puerto Rico.
She also received her master's degree in quality management from the Massachusetts National Graduate School in 2004.
Defense Department officials said Ortiz died Tuesday "of wounds suffered from enemy indirect fire."
A memorial service is scheduled for 3 p.m. Wednesday at Aberdeen's chapel, said Pat McClung, an Aberdeen spokeswoman.
