“Vice Adm. William H. McRaven, one of the most experienced terrorist hunters in the U.S. government, had tapped a special unit of Navy SEALs for the mission two months earlier. A former SEAL himself, McRaven had overseen weeks of intensive training for a covert operation that could cripple al-Qaeda if it worked, or strain an already troubled alliance with Pakistan if it went awry.
He has worked almost exclusively on counterterrorism operations and strategy since 2001, when as a Navy captain he was assigned to the White House shortly after the Sept. 11 attacks. The author of a textbook titled “Spec Ops,†McRaven had long emphasized six key requirements for any successful mission: surprise, speed, security, simplicity, purpose and repetition.
For the especially risky bin Laden operation, he insisted on another: precision.”
