Evidence offered of harm done by Manning leaks

FORT MEADE, Md. -- The mountain of classified material Army Pfc. Bradley Manning gave to the anti-secrecy organization WikiLeaks revealed sensitive information about military operations and tactics, including code words and the name of at least one enemy target, according to evidence the government presented Tuesday.

Manning, a 25-year-old Oklahoma native, has said he didn't believe the more than 700,000 battlefield reports, diplomatic cables and video clips he leaked while working as an intelligence analyst in Baghdad would hurt national security. Prosecutors want to convict him of aiding the enemy, which carries a potential life sentence.

For the first time, prosecutors presented evidence that Manning's leaks compromised sensitive information in dozens of categories. The defense and prosecutors accepted written statements as substitutions for live testimony. They were read aloud in court.

One statement by a classification expert, retired Air Force Lt. Col. Martin Nehring, said his review of Afghanistan and Iraq battlefield reports revealed techniques for neutralizing improvised explosives, the name of an enemy target, the names of criminal suspects and troop movements.

Navy Reserve Lt. Cmdr. Thomas Hoskins said he found leaks of Afghanistan battlefield reports had revealed code words, tactics and techniques for responding to roadside bombings and weapon capabilities.
