Marcus Luttrell (born November 7, 1975) is a retired United States Navy SEAL who received the Navy Cross and Purple Heart for his disputed actions in June 2005 against Taliban fighters during Operation Red Wings in which he was the lone survivor. Marcus Luttrell was saved because a kind-hearted Afghan villager named Mohammad Gulab found him, provided shelter, and protected him from the Taliban, following the traditional Pashtunwali code of hospitality. Gulab then alerted American forces, leading to a massive rescue operation that extracted the wounded and gravely injured SEAL. Luttrell became an SO1 by the end of his eight-year career in the United States Navy.

Luttrell co-hosts After Action, a TV show in which former special operations veterans talk about issues in the United States. Glenn Beck is the executive producer of the show, which airs on TheBlaze.

Luttrell was born in Houston, Texas, on November 7, 1975. He began training for the U.S. Navy SEALs at the age of 14, with U.S. Army veteran Billy Shelton, who lived near Luttrell's home. Luttrell trained every day with his twin brother, Morgan, and others who aspired to join the U.S. Navy and other special operations forces. Shelton trained them using various weight and endurance exercises. After high school at Willis High School, Willis, Texas, Luttrell attended Sam Houston State University where he was a member of the Epsilon Zeta chapter of Delta Tau Delta fraternity. He departed school in 1998 without graduating to enlist in the Navy.

Luttrell enlisted in the U.S. Navy in March 1999. After graduating from boot camp and Hospital Corpsman A-school, he transferred to Basic Underwater Demolition/SEAL (BUD/S) Class 226. However, due to a fractured femur he suffered from falling off a rope, he graduated with BUD/S class 228 on April 21, 2000. During BUD/S, Luttrell had his civilian twin brother Morgan impersonate him for several days in order to get rested. After completing BUD/S, Luttrell attended Army jump school and SEAL Qualification Training (SQT). Luttrell earned his Navy Enlisted Classification (NEC) 5326 Combatant Swimmer (SEAL) and Naval Special Warfare Insignia on February 2, 2001, after completing SQT. He was then sent to Fort Bragg, North Carolina, for the Special Operations Combat Medic (SOCM) course. SOCM was an additional six months of advanced training in conventional and unconventional medical skills, ranging from diagnosis and treatment of many conditions to advanced emergency medicine and battlefield life support. He was deployed to Iraq with SEAL Team 5 on April 14, 2003, during the 2003 invasion of Iraq, to root out and destroy leftover Iraqi resistance and joined in the search for WMDs. Afterward, he carried out operations to eliminate or capture terrorists.

He was deployed to Afghanistan in 2005 with SEAL Team Ten as part of SEAL Delivery Vehicle Team One (SDV-1). While in Afghanistan, he was involved in Operation Red Wings, during which the four-man Special Reconnaissance element with SDV-1 was noticed by local herdsmen. The team understood that the local herdsmen might reveal their whereabouts to Taliban fighters but also recognized that the herdsmen were unarmed and did not appear to be combatants. Despite the risk, the SEAL team allowed the herdsmen to leave. Soon thereafter, the SEAL team was ambushed, and only Luttrell survived. Luttrell was awarded the Navy Cross for his actions during the operation.

During the ambush of Operation Red Wings the four SEALs were attacked from three sides and took fire from RPK machine guns, AK-47s, RPG-7s, and 82mm mortars. The attack forced the SEALs into the northeast gorge of the Shuryek Valley side of Sawtalo Sar. The SEALs made a number of attempts to contact their combat operations center with a PRC-148 MBITR (Multi Band Inter/Intra Team Radio) and then with an Iridium satellite phone. They could not establish consistent communication, however, other than for a period long enough to indicate that they were under attack. Three of the four team members were killed, and Luttrell, the only survivor, was left unconscious with a number of fractures, a broken back, and numerous shrapnel wounds. Members of SEAL Team 10 attempted a rescue during the firefight, but their helicopter was shot down, and all aboard were killed. Luttrell regained consciousness and evaded the pursuing enemy, with the help of local Pashtun villagers, one of them being Mohammad Gulab, who eventually sent an emissary to the nearest U.S. base to secure Luttrell's safe rescue and ultimately saved his life.

Luttrell was rescued on July 2 by Army Rangers and Afghan National Army soldiers in the woods when Gulab and several villagers were trying to get Luttrell to a safe location. United States Air Force Pararescuemen (PJs) from the 59th Expeditionary Rescue Squadron (305th Rescue Squadron deployed) Josh Appel and Chris Piercecchi were involved in the rescue and recovery of Luttrell. Based on Luttrell's descriptions of the area, Appel and Piercecchi returned to the site of the battle two days later and retrieved the remains of Dietz, Murphy and Axelson.

The target of Operation Red Wings, Mohammad Ismail alias Ahmad Shah, survived the American operation but was killed during a firefight with Pakistani police in Khyber Pakhtunkhwa in April 2008.
