British and US forces handed over Camp Bastion, which served as the British headquarters in the country, to Afghan forces on Oct. 26. The base, along with neighboring Camp Leatherneck, which was the US Marine headquarters in the south, were the main hubs of counterinsurgency and air operations against the Taliban in Helmand, Nimroz, and Farah provinces. Leatherneck was also turned over to Afghan control on Oct. 26.
The Taliban have successfully breached security at Camp Bastion once in the past. On Sept. 14, 2012, a 15-man Taliban team penetrated the perimeter at the airbase, destroyed six USMC Harriers and damaged two more, and killed the US squadron commander and a sergeant. Fourteen of the 15 members of the assault team were killed, while the last was wounded and captured. Coalition forces captured one of the leaders of the operation days later, while the Taliban released a video that highlighted the attack.
