The Cyprus Port and Marine Police (Greek Λιμενική και Ναυτική Αστυνομία - Limeniki kai Nautiki Astinomia) fulfills the functions of other countries' coast guards for the Republic of Cyprus. Cyprus is an island country in the Eastern Mediterranean with almost 40% of its territory under occupation after a Turkish military Invasion. Due to the country's geopolitical situation, size, the recent discovery in 2011 of the Aphrodite gas field in its Exclusive Economic Zone and Cyprus Police being the main national Law enforcement agency, the duties and responsibilities of the Cyprus Port and Marine Police are many and sometimes complex. It is a unit of the Cyprus Police, which resides under the Ministry of Justice and Public Order (Cyprus). However it can support the Cyprus Navy in wartime which resides under the Ministry of Defence. It is staffed by Police Officers which can be transferred to and from other units and agencies of the Cyprus Police and are tasked with the primary mission of policing the country's sea borders and the law enforcement of the waters around it. The unit is equipped with patrol boats and radars but it does not operate its own helicopters. Instead, it operates in combination with the aerial unit of the Cyprus Police, the Cyprus Police Aviation Unit. Main roles include law enforcement against illicit activities such as smuggling (due to the fact that although the Customs and Excise Department is a separate agency under the Ministry of Finance, it does not have an operational or tactical team of its own), terrorism, piracy, illegal fishing, Illegal drug trade, illegal immigration and is also assigned with Search and Rescue (SAR) duties. For counter-terrorism and anti-piracy operations, the units operate in combination with the Special Anti-Terrorist Squad which is part of the Emergency Response Unit of the Cyprus Police. Although the prominent agencies responsible for all Search and Rescue operations are conducted by Cyprus Police Units, the agency responsible to organize the SAR system, to co-ordinate, to control and direct SAR operations in the region that the Republic of Cyprus is responsible for (which coincides with the Nicosia FIR) is the Cyprus Joint Rescue Coordination Center or JRCC Larnaca, which is an independent agency of the Ministry of Defence.
