FOB Salerno is a forward operating base of the U.S. military in the southeastern province of Khost, Afghanistan, near the city of Khost. It has been nicknamed "Rocket City" due to the large amounts of incoming rocket and mortar fire in previous years. The facility was built by TF Panther in 2002, centered around the 3rd Battalion, 505th Parachute Infantry Regiment from Fort Bragg, North Carolina. It was named for the beachhead in Salerno that the 505th PIR parachuted onto on 14 September 1943 (Operation Avalanche).
