WASHINGTON: The US Navy commando who wrote an account of the raid that killed Osama bin Laden under a pseudonym was identified Thursday as Matt Bissonnette, who retired from the Navy last summer.  

Bissonnette was first identified by Fox News. One current and one former U.S. military official confirmed the name, speaking on condition of anonymity because they were not authorized to discuss military personnel matters.

The book, ''No Easy Day,'' is scheduled to be released Sept. 11, with the author listed under the pseudonym of Mark Owen. Penguin Group (USA)'s Dutton imprint, the publisher, asked news organizations Thursday to withhold his identity.

''Sharing the true story of his personal experience in 'No Easy Day' is a courageous act in the face of obvious risks to his personal security,'' Dutton spokeswoman Christine Ball said in a statement. ''That personal security is the sole reason the book is being published under a pseudonym.''

Bissonnette also changed the names of the other SEALs in the account, the publisher says. Navy commandos are known as SEALs.

Special Operations Command spokesman Col. Tim Nye said the retired SEAL could be endangered by being identified, which could also expose those active-duty SEALs the author worked with in the killing of bin Laden in Abbottabad, Pakistan, last year.

The book and the author's name also come out amid debate over the possible damage to U.S. national security by leaks in the media about top secret operations. Yet the book also comes at a time when special operations forces are prominently featured in the media as never before, even as the elite organizations demand secrecy.

Efforts to locate Bissonnette for comment were unsuccessful.

A rash of new books trumpet special operators' exploits. For example, ''American Sniper,'' a best-seller by recently retired SEAL Chris Kyle, details his 150-plus kills of insurgents from 1999 to 2009.

A handful of special operations advocacy groups have sprung up decrying leaks, but they identify themselves by name as former members of some of the elite units, in an online campaign video that slams President Barack Obama for releasing details of the bin Laden raid.

One of the advocacy groups is run by retired Navy SEAL Ryan Zinke, who prominently mentions his time years ago at SEAL Team 6, the top secret unit that carried out the bin Laden raid.

Even Special Operations Command made an exception to its normal reticence with the media when it signed off on this year's movie ''Act of Valor,'' which followed real active duty SEALs carrying out training exercises that were turned into what looked like real action scenes for the film.

The author of ''No Easy Day'' is slated to appear in shadow in promotional interviews for the book, meant to conceal his identity. The book is already listed as one of the top 10 books on Amazon.com and Barnes & Noble.com.

Beyond the risk he faces now that his identity is known, he could also face legal trouble if the Pentagon determines that he disclosed classified information in the account.

US military and intelligence officials say they do not believe the book has been read or cleared by the Defense Department. The Pentagon reviews publications by military members, both active duty and retired, to make sure that no classified material is disclosed.
