Spc Manning is also alleged to have abused access to a secret-level network to obtain more than 150,000 US state department cables, some of them classified. More than 50 cables are said to have been passed to an unauthorised person.
If convicted of all charges, he could face a prison sentence of between 50 to 70 years, according to army spokesman Lt Col Eric Bloom.
Col Bloom told the BBC that the next step would be an Article 32 hearing, at which time an investigating officer will determine whether the case should go to court-martial.
In the meantime, Spc Manning was free to retain his own counsel and make telephone calls, he added. It has yet to be decided if any court-martial would be open to the public.
Spc Manning is said to have confessed to leaking the video of the helicopter attack to WikiLeaks in a series of online chats with a former computer hacker, Adrian Lamo.
He allegedly also admitted handing over other items to WikiLeaks, including a classified army document assessing the threat level of the website, which promotes the leaking of information by whistleblower"If the charges against Manning are true, he will be the Daniel Ellsberg of our times," it said, referring to the US military strategist who leaked 7,000 pages of top-secret documents in an effort to halt the Vietnam War.
Excellent. Bust his sorry ass.
