The Chinook CH-47 transport helicopter was carrying U.S. and Afghan military forces on a night-raid mission in the Tangi Valley of Afghanistan’s Wardak province around 1 a.m. on August 6, 2011, when Afghan insurgents shot it down using a rocket-propelled grenade. Thirty Americans and eight Afghans were killed in the attack and the helicopter’s subsequent crash. Seventeen of the U.S. servicemen killed were Navy SEALs, including 15 commandos from the Gold Squadron of the elite Naval Warfare Development Group (DEVGRU), better known as SEAL Team Six. The Taliban immediately claimed responsibility for the attack, which proved to be not only the costliest day in Team Six history but also the single deadliest day for U.S. forces during the war in Afghanistan, which by that point had lasted nearly 10 years.
