Firebase Tinsley, formerly known as Firebase Cobra, is a United States military fire support base, located in Oruzgan Province in Afghanistan. This base was established by the Charlie Company "Cobras" of the 2nd Battalion, 5th Infantry who were deployed with the 25th Infantry Division (Light) out of Schofield Barracks, Hawaii. The base was named Firebase Cobra until the death of Capt. John Tinsley near there in August 2009. It was featured in National Geographic's "Inside the Green Berets" television series. The U.S. Army's 3rd Special Forces Group is stationed there.
