In addition, the mainland Turkish Armed Forces maintains the Cyprus Turkish Peace Force which consists of around 30,000–40,000 troops drawn from the 9th Turkish Army Corps and comprising two divisions, the 28th and 39th. It is equipped with a substantial number of US-made M48 Patton main battle tanks and artillery weapons. The Turkish Air Force, Turkish Navy and Turkish Coast Guard also have a presence in Northern Cyprus. Although formally part of Turkish 4th Army, headquartered in İzmir, the sensitivities of the Cyprus situation means that the commander of the Cyprus Turkish Peace Force also reports directly to the Turkish General Staff in Ankara. The Cyprus Turkish Peace Force is deployed principally along the Green Line and in locations where hostile amphibious landings might take place.
