Known only as The Shooter the man will be unmasked in a Fox News documentary on the operation to find and kill Bin Laden, who masterminded the 9/11 terror attacks.

The two-part show – titled The Man Who Killed Osama Bin Laden – will air in November.

The documentary will provide new information about Operation Neptune Spear, the mission to find the al-Qaida leader.

Fox have revealed The Shooter will also reveal what it was like to confront Bin Laden and to be there as he took his final breath.

Since retiring the special-forces soldier has reportedly suffered a breakdown in his marriage and was so concerned about keeping his identity secret he refused to meet families of 9/11 victims.

Speaking to Esquire last year the Seal recalled being surprised by Bin Laden's appearance.

"And I remember as I watched him breathe out the last part of air, I thought: Is this the best thing I've ever done, or the worst thing I've ever done?" he said.

"This is real and that's him. Holy s***."

Bin Laden was killed in Pakistan on May 2, 2011, during a CIA-led operation on a compound in Abbottabad, Pakistan.

The hunt for Bin Laden inspired the Oscar-winning film Zero Dark Thirty starring Jessica Chastain as a female CIA agent who spent years trying to locate the terrorist.
