Question: Ten Rules for Air Fighting were developed by the fighter pilot from what branch of the armed forces?
Context: Adolph Gysbert Malan DSO & Bar DFC (24 March 1910 – 17 September 1963), better known as Sailor Malan, was a South African World War II fighter pilot who led No. 74 Squadron RAF during the height of the Battle of Britain.  Malan developed a set of simple rules for fighter pilots, which eventually could be found throughout RAF Fighter Command: The Soviet Air Defence Forces (Russian: войска ПВО , voyska protivovozdushnoy oborony, voyska PVO, V-PVO, lit.  "Anti-Air Defence Troops"; and formerly protivovozdushnaya oborona strany, PVO strany, lit.  "Anti-Air Defence of the Nation") was the air defence branch of the Soviet Armed Forces.  It continued being a service branch of the Russian Armed Forces from 1991 to 1998.  Unlike Western air defence forces, V-PVO was a branch of the military unto itself, separate from the Soviet Air Force (VVS) and Air Defence Troops of Ground Forces.  During the Soviet period it was generally ranked third in importance of the Soviet services, behind the Strategic Rocket Forces and the Ground Forces. The United States Air Force (USAF) is the aerial and space warfare service branch of the United States Armed Forces and one of the seven American uniformed services.  Initially part of the United States Army, the USAF was formed as a separate branch of the U.S. Armed Forces on 18 September 1947 under the National Security Act of 1947.  It is the most recent branch of the U.S. Armed Forces to be formed.  The USAF is the largest and one of the most technologically advanced air forces in the world.  The service articulates its core functions as Nuclear Deterrence Operations, Air Superiority, Space Superiority, Cyberspace Superiority, Command and Control, Global Integrated ISR, Global Precision Attack, Special Operations, Rapid Global Mobility, Personnel Recovery, Agile Combat Support, and Building Partnerships. Oswald Boelcke (] ; 19 May 1891 – 28 October 1916) was a German flying ace of the First World War and one of the most influential patrol leaders and tacticians of the early years of air combat.  Boelcke is considered the father of the German fighter air force, as well as the "Father of Air Fighting Tactics".  He was the first to formalize rules of air fighting, which he presented as the "Dicta Boelcke".  While he promulgated rules for the individual pilot, his main concern was the use of formation fighting rather than single effort. The Italian Armed Forces (italian: "Forze armate italiane") encompass the Italian Army, the Italian Navy and the Italian Air Force.  A fourth branch of the armed forces, known as the Carabinieri, take on the role as the nation's military police and are also involved in missions and operations abroad as a combat force.  Despite not being a branch of the armed forces, the Guardia di Finanza is part of the military and operates a large fleet of ships, aircraft and helicopters, enabling it to patrol Italy's waters and to eventually participate in warfare scenarios.  These five forces have military status and are all organized along military lines, comprising a total of 350,000 men and women with the official status of active military personnel.  The President of the Italian Republic heads the armed forces as the President of the High Council of Defence established by article 87 of the Constitution of Italy.  According to article 78, the Parliament has the authority to declare a state of war and vest the necessary powers in the Government. The Serbian Armed Forces (Serbian: Војска Србије / "Vojska Srbije" ) are the armed forces of Serbia.  The armed forces consist of the Serbian Army and the Serbian Air Force and Air Defence.  The Commander-in-Chief of the armed forces is the President of the Republic.  The Serbian Armed Forces are a professional and volunteer based military.  Serbia exercises civilian control of the military through the Ministry of Defence. The Spanish Armed Forces (Spanish: "Fuerzas Armadas Españolas" , FFAA) are the military forces of the Kingdom of Spain.  The Spanish Armed Forces are a modern military force charged with defending the Kingdom's integrity and sovereignty.  They consist of the Army, Navy and Air Force.  The King is the Commander-in-Chief of the armed forces, with the title "Capitán General de las Fuerzas Armadas" (Captain General of the Armed Forces).  The current Chief of the Defence Staff is General Fernando Alejandre Martínez.  The Spanish Armed Forces are active members of NATO, the Eurocorps, the European Union Battlegroups, and also provide peace keeping troops to the United Nations. Chief Warrant Officer is a military rank used by the United States Armed Forces, the Canadian Armed Forces, the Pakistan Air Force, the Israel Defense Forces, the South African National Defence Force, the Lebanese Armed Forces and, since 2012, the Singapore Armed Forces.  In the United States Armed Forces Chief Warrant Officers are actual officers, not NCOs like other NATO forces. Adolph Gysbert Malan, (24 March 1910 – 17 September 1963), better known as Sailor Malan, was a South African fighter pilot and flying ace in the Royal Air Force (RAF) who led No. 74 Squadron RAF during the height of the Battle of Britain.  Under his leadership No. 74 Squadron became one of the RAF's most accomplished squadrons.  Malan scored 27 kills, seven shared destroyed, three probably destroyed and 16 damaged. The Sudanese Armed Forces (SAF) are the Armed Forces of the Republic of Sudan.  According to 2011 IISS estimates, it numbers 109,300 personnel.  They comprises Land Forces, the Sudanese Navy, the Sudanese Air Force, and the Popular Defence Forces.  They also previously had Joint Integrated Units formed together with its rebel enemies the Sudan People's Liberation Army.  The Armed Forces operate under the authority of the People's Armed Forces Act 1986.  In 1991, the Library of Congress used the term "Sudan People's Armed Forces" to refer to the entire armed forces, but by the late 2000s (decade), the "Sudanese Armed Forces" term was most widespread.  In 2004, the Federal Research Division of the Library of Congress estimated that the Popular Defence Forces, the military wing of the National Islamic Front, consists of 10,000 active members, with 85,000 reserves.  It has been deployed alongside regular army units against various rebel groups.
