The U.S. Navy SEALs on the hunt for Usama bin Laden killed the Al Qaeda leader within 2 minutes of entering his fortress-like home in Pakistan, a new book reveals.

Chuck Pfarrer, a former SEAL Team Six assault-element commander, says it only took the SEALs 90 to 120 seconds � from landing to firing the fatal shot � to take out bin Laden, according to his new book, �Seal Target Geronimo,� the New York Post reports.

Pfarrer insists that the SEALs were not on a �kill mission,� and that the team would have captured bin Laden had he surrendered.

Pfarrer�s book reveals that the Seals� nickname for bin Laden and his deputy, Ayman al-Zawahiri, were Bert and Ernie, the Courier Mail reports.

When they were first told they were going to Pakistan to pick up a high-value person who was holed up in a high-walled compound, they asked, �So is this Bert or Ernie?�

According to an extract from a Sunday Times report, two Seals kicked in bin Laden�s bedroom door. Bin Laden then popped out and then slammed the door shut.

The room, the Navy Seals recalled, �smelt like old clothing, like a guest bedroom in a grandmother�s house�.

Inside was the Al Qaeda leader and his youngest wife, Amal, who was screaming as he pushed her in front of him.

�No, no, don�t do this!� she shouted as her husband reached across the bed for his AK-47 assault rifle,� the extract read.

The SEALs reacted instantly, firing in the same second. One round thudded into the mattress. The other aimed at Bin Laden�s head, grazed Amal in the calf.

As Bin Laden�s hand reached for the gun, the Seals fired again, killing the Al Qaeda leader.

Pfarrer�s book, according to the Post, also reveals that the SEALs were angry with President Obama for announcing bin Laden�s death on TV just hours after they completed the mission on May 1.
