Malan developed a set of simple rules for fighter pilots, which eventually could be found throughout RAF Fighter Command:

Soviet Air Defence Forces: 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.

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: 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.

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.
