According to the mission plan, the first helicopter would hover over the compound's yard while its full team of SEALs fast-roped to the ground. At the same time, the second helicopter would fly to the northeast corner of the compound and deploy the interpreter, the dog and handler, and four SEALs to secure the perimeter. The team in the courtyard was to enter the house from the ground floor. As they hovered above the target, however, the first helicopter experienced a hazardous airflow condition known as a vortex ring state. This was aggravated by higher than expected air temperature and the high compound walls, which stopped the rotor downwash from diffusing. The helicopter's tail grazed one of the compound's walls, damaging its tail rotor, and the helicopter rolled onto its side. The pilot quickly buried the aircraft's nose to keep it from tipping over. None of the SEALs, crew and pilots on the helicopter were seriously injured in the soft crash landing, which ended with it pitched at a 45-degree angle resting against the wall. The other helicopter landed outside the compound and the SEALs scaled the walls to get inside.
Declaring that the moment of reckoning has come and that the sounds they can hear are those of approaching U.S. helicopters, bin Laden instructs everyone to leave him. Outside, members of SEAL Team Six, containing Pashto and Arabic speakers are already inside the compound - having survived the crash landing of one of the two stealth Black Hawk helicopters that transported them from the eastern Afghan city of Jalalabad, almost 200 miles away. Inside the annexe of the large property, Ibrahim al-Kuwaiti, bin Laden's favorite courier is awoken by the loud noise from the detonation of a charge placed on the gate to the compound. Going to answer a knock on a door, al-Kuwaiti is shot dead as a bullet hits him through the window - dying never knowing that he inadvertently led the CIA to bin Laden in Abbottabad after CIA analysts were tipped off by Guantanamo inmates that he was close to the terror lord.
Inside the main building, bin Laden's daughter Mariam has not left him as instructed, nor has his wife Sadah. Mariam steps out onto the balcony as instructed and then suddenly a blast rings out and they hear footsteps on the roof and footsteps on the stairs. The SEALs encountered bin Laden on the third floor of the main building. Bin Laden was "wearing the local loose-fitting tunic and pants known as a kurta paijama", which were later found to have €500 and two phone numbers sewn into the fabric. Bin Laden peered through his bedroom door at the Americans advancing up the stairs, and then retreated into the room as the lead SEAL fired a shot at him, which either missed or hit him in the side. Robert O'Neill, who later publicly identified himself as the SEAL who shot bin Laden, rolled through the door and confronted bin Laden inside the bedroom. It is then that Sadah sees the ghostly figure of a Navy SEAL on the landing outside the bedroom aiming his red laser dot onto her husband. Throwing herself at the soldier, he screams 'No!No!' and he shoots her in the knee.
O'Neill states that bin Laden was standing behind a woman with his hands on her shoulders, pushing her forward. O'Neill immediately shot bin Laden twice in the forehead, then once more as bin Laden crumpled to the floor. Matt Bissonnette, who entered the room at about the same time, also claims to have fired shots into bin Laden's fallen body. More shots follow and as she lies injured on the bed she hears a soldier repeatedly asking Sumayya and Mariam the name of the man who now lies dead on the floor. With a wound on his forehead and blood flowing out onto the floor, the girls confirm that the man is indeed their father, Osama bin Laden. 3,520 days after the attacks that rocked the United States and killed 2,977 Americans, the mastermind of the 9/11 terror attacks lay dead at the feet of an American Sailor. The SEAL Team 6 leader radioed, "For God and country—Geronimo, Geronimo, Geronimo", and then, after being prompted by Vice Admiral McRaven for confirmation, "Geronimo EKIA."
The weapon used to kill bin Laden was a Heckler & Koch HK416 using 5.56mm NATO 77-grain open-tip match rounds manufactured by Black Hills Ammunition. The HK416 rifle is available to civilians in semi-automatic form -- marketed as the Heckler & Koch MR556 -- and they are fucking expensive. But I suppose you get what you pay for.
