An Army reservist who appeared in several of the most infamous abuse photos taken by guards at Abu Ghraib prison was sentenced Tuesday to six months in prison for her role in the scandal that rocked the U.S. military's image at home and abroad.

The sentence for Spc. Sabrina Harman came a day after she was convicted on six of the seven counts she faced for mistreating detainees at the Baghdad lockup in late 2003. She faced a maximum of five years in prison, though prosecutors asked the jury to give her three years.

With credit for time served, Harman's actual sentence will be just more than four months.

Harman, 27, of Lorton, Va., was the second U.S. soldier tried and convicted in the scandal.

During Tuesday's sentencing hearing, she tearfully apologized for mistreating Iraqi prisoners at Abu Ghraib.

"As a soldier and military police officer, I failed my duties and failed my mission to protect and defend," Harman said, her voice cracking. "I not only let down the people in Iraq, but I let down every single soldier that serves today.

"My actions potentially caused an increased hatred and insurgency towards the United States, putting soldiers and civilians at greater risk," she continued. "I take full responsibility for my actions ... The decisions I made were mine and mine alone."

The jury of four Army officers and four senior enlisted soldiers deliberated for less than four hours Monday before convicting Harman on one count of conspiracy to maltreat detainees, four counts of maltreating detainees and one count of dereliction of duty.

She was acquitted of allegedly photographing a group of Iraqi prisoners forced to masturbate in public by Abu Ghraib guards. One of Harman's co-defendants testified last week that she was not present when that incident occurred.

Harman, a former pizza shop manager from Lorton, Virginia, appeared in several of the most notorious photos taken at Abu Ghraib, and she was found guilty of taking other pictures.

The photos showed prisoners chained together in sexual poses, piled on the floor naked and forced to form a nude human pyramid.

In one picture, Harman posed with Graner behind a group of naked detainees. In another, she was shown with a prisoner on whose leg she is accused of writing "rapeist."

In closing arguments Monday, prosecutors said Harman and other guards conspired to physically hurt and sexually humiliate the prisoners under their watch.
