The Pakistan Army, a major component of the Pakistani military alongside the Pakistan Navy and Pakistan Air Force, is a volunteer force that has seen extensive combat during three major wars with neighbouring India, several border skirmishes on its porous border with Afghanistan as well as a long-running insurgency in Balochistan which it has been combatting alongside Iranian security forces since 1948. Since the 1960s, elements of the army have been repeatedly deployed to act in an advisory capacity in the Arab states during the events of the Arab–Israeli wars as well as to aid the United States-led coalition against Iraq in the First Gulf War. Other notable military operations during the global war on terrorism in the 21st century included: "Zarb-e-Azb", "Black Thunderstorm", and "Rah-e-Nijat".
