Camp Leatherneck was a 1,600 acre United States Marine Corps base in Helmand Province, Afghanistan. The site was mostly in Washir District and was conjoined with Camp Bastion, which was the main British military base in Afghanistan and Camp Shorabak which initially was the main Afghan section however the three sites were joined under the name of 'Camp Shorabak' in 2014. Control of the site was transferred from the International Security Assistance Force (ISAF) to the Afghan Armed Forces on 26 October 2014. History Camp Leatherneck was master-planned by the United States Army Corps of Engineers (USACE) Europe District FEST-A Team from Wiesbaden, Germany in October/November 2008. Upon arrival to Kandahar, the team was tasked by the Theater Engineer of U.S. Forces Afghanistan (USFOR-A) to find a suitable location in Helmand Province for 2K-15K troops. The primary purpose for the base was to house troops for a majority of an estimated 26,000 additional U.S. troops being deployed to Afghanistan. Throughout all of southern Afghanistan, bases were all at or above capacity leading to the paramount need for a large centrally located base for the surge. The site was chosen primarily to take advantage of the adjacent British Airfield on Camp Bastion and to provide much needed protection to the primary east–west corridor of Highway 1 in Helmand Province. The 25th Naval Construction Regiment (25th NCR) was the primary construction unit with construction oversight and the command element that the FEST Design team was later attached during the initial stages of construction. The units responsible for the overall construction work in 2008 under the 25th NCR was the Naval Mobile Construction Battalions Seven, Five, and Seventy-Four. Camp Leatherneck was built in a modular fashion to maximize the efficiency of construction locations to provide housing and work space as surge forces flowed into theater. The base layout was designed in modular 'blocks', so the base could have forces on the ground as construction continued in adjacent compartments. All aspects of the design were focused on the speed for construction and with the understanding that the number of troops was unknown. Initially dubbed Tombstone II as an expansion of a smaller Special Forces Camp adjacent to the ANA Shorabak base, it was eventually renamed Camp Leatherneck once it was formally announced that I Marine Expeditionary Force would move to southern Afghanistan and determined the main force occupying the base in 2009.
