The rank is also used by the air forces of many countries which have historical British influence and it is sometimes used as the English translation of an equivalent rank in countries which have a non-English air force-specific rank structure. Air vice-marshals may be addressed generically as "air marshal". Air vice-marshal is a two-star rank and has a NATO ranking code of OF-7. It is equivalent to a rear-admiral in the Royal Navy or a major-general in the British Army or the Royal Marines. In other NATO forces, such as the United States Armed Forces and the Canadian Armed Forces, the equivalent two-star rank is major general. - The Royal New Zealand Air Force (RNZAF) (Maori: "Te Tauaarangi o Aotearoa", previously "Te Hokowhitu o Kahurangi") is the air force component of the New Zealand Defence Force. It was formed from New Zealand elements of the British Royal Air Force, becoming an independent force in 1923, although many RNZAF aircrew continued to serve in the Royal Air Force until the end of the 1940s. The RNZAF fought in World War II, Malaysia, Korean War, Vietnam and the Gulf War plus various United Nations peacekeeping missions. From a 1945 peak of over 1,000 combat aircraft the RNZAF has shrunk to a strength of around 51 aircraft in 2016, focusing on maritime patrol and transport duties in support of the Royal New Zealand Navy and the New Zealand Army. The RNZAF's air combat capability ended in 2001 with the disbanding of the A-4 Skyhawk squadrons. The Air Force is led by an air vice-marshal who holds the appointment of Chief of Air Force. - The New Zealand Army ("Tribe of the God of war") is the land component of the New Zealand Defence Force and comprises around 4,500 Regular Force personnel, 2,000 Territorial Force personnel and 500 civilians. Formerly the New Zealand Military Forces, the current name was adopted by the New Zealand Army Act 1950. The New Zealand Army traces its history from settler militia raised in 1845. - The Royal Air Force (RAF) is the United Kingdom's aerial warfare force. Formed towards the end of the First World War on 1 April 1918, it is the oldest independent air force in the world. Following victory over the Central Powers in 1918 the RAF emerged as, at the time, the largest air force in the world. Since its formation, the RAF has taken a significant role in British military history, in particular, playing a large part in the Second World War where it fought its most famous campaign, the Battle of Britain. - World WarII (often abbreviated to WWII or WW2), also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the world's nationsincluding all of the great powerseventually forming two opposing military alliances: the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. In a state of "total war", the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, erasing the distinction between civilian and military resources. Marked by mass deaths of civilians, including the Holocaust (in which approximately 11 million people were killed) and the strategic bombing of industrial and population centres (in which approximately one million were killed, and which included the atomic bombings of Hiroshima and Nagasaki), it resulted in an estimated 50 million to 85 million fatalities. These made World WarII the deadliest conflict in human history. - New Zealand is an island nation in the southwestern Pacific Ocean. The country geographically comprises two main landmassesthat of the North Island, or Te Ika-a-Mui, and the South Island, or Te Waipounamuand numerous smaller islands. New Zealand is situated some east of Australia across the Tasman Sea and roughly south of the Pacific island areas of New Caledonia, Fiji, and Tonga. Because of its remoteness, it was one of the last lands to be settled by humans. During its long period of isolation, New Zealand developed a distinct biodiversity of animal, fungal and plant life. The country's varied topography and its sharp mountain peaks, such as the Southern Alps, owe much to the tectonic uplift of land and volcanic eruptions. New Zealand's capital city is Wellington, while its most populous city is Auckland. - Air Vice Marshal John Henry Staples Hamilton ONZM , MVO is a former senior commander in the Royal New Zealand Air Force , serving as Chief of Air Force from 2002 until his retirement in 2006 .
