Context: The modern United States Navy Baseball Club was founded by retired U.S. Navy Commander Terry Allvord in Pensacola, Florida in 1990 before moving to San Diego for the 1993 season.  This program is the leader in armed forces baseball in the modern era.  Allvord went on to establish over 40 single-service armed forces teams in every branch of the military around the globe.  Tryouts are held every year to form the most talented military and first responders team to compete as the U.S. Military All-Stars during the annual "Red, White and Blue Tour" The team features active duty, reserve, veterans, Delayed Entry Program and first responders.  The continuation of two wars has limited the availability of armed forces players.  As a result, beginning in 2010, the team will be known as the "Heroes of the Diamond" allowing a limited number of former MLB, current professional, summer collegiate and first responders the opportunity to join the tour.  Players interested in the military and willing to support the mission will continue to pay their own expenses while off-duty to compete against the finest professional, independent and summer collegiate programs in the world. 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 Chiefs of Staff Committee (CSC) is composed of the most senior military personnel in the British Armed Forces who advise on operational military matters and the preparation and conduct of military operations.  The committee consists of the Chief of the Defence Staff who is the chairman and professional head of the forces, the Vice-Chief of the Defence Staff, who is the vice-chairman and deputy professional head of the armed forces.  The Committee also consists of the professional heads of each branch of the armed forces: the First Sea Lord and Chief of the Naval Staff, the Chief of the General Staff and the Chief of the Air Staff. 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. The Turkish Land Forces (Turkish: "Türk Kara Kuvvetleri" ), or Turkish Army (Turkish: "Türk Ordusu" ), is the main branch of the Turkish Armed Forces responsible for land-based military operations.  Official claims state that the army was founded by Modu Chanyu of the Xiongnu Empire in 209 BC, but the modern history of the army began with its formation after the collapse of the Ottoman Empire.  Significant events since the foundation of the Army include combat in the Korean War and in the 1974 Turkish invasion of Cyprus, and acting as a NATO bulwark along Cold War frontiers through 1992.  The army holds the preeminent place within the armed forces.  It is customary for the Chief of the General Staff of the Republic of Turkey to have been the Commander of the Turkish Land Forces prior to his appointment as Turkey's senior ranking officer.  Alongside the other two armed services, the Turkish Army has frequently intervened in Turkish politics, which has now been regulated to an extent with the reform of the National Security Council.  The current commander of the Turkish Land Forces is General Salih Zeki Çolak. 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. Jeana Yeager is an American aviator.  She co-piloted, along with Dick Rutan, the first non-stop, non-refueled flight around the world in the Rutan Voyager aircraft from December 14 to 23, 1986.  The flight took 9 days, 3 minutes, and 44 seconds and covered 24,986 miles (40,211 km), more than doubling the old distance record set by a Boeing B-52 bomber in 1962. The Rutan Model 76 Voyager was the first aircraft to fly around the world without stopping or refueling.  It was piloted by Dick Rutan and Jeana Yeager.  The flight took off from Edwards Air Force Base's 15,000 foot (4,600 m) runway in the Mojave Desert on December 14, 1986, and ended 9 days, 3 minutes and 44 seconds later on December 23, setting a flight endurance record.  The aircraft flew westerly 26,366 statute miles (42,432 km; the FAI accredited distance is 40,212 km) at an average altitude of 11,000 feet (3,350 m). An exchange officer is a commissioned officer in a country's armed forces who is temporarily seconded either to a unit of the armed forces of another country or to another branch of the armed forces of their own country. Richard Glenn "Dick" Rutan (born July 1, 1938) is a retired United States Air Force pilot and record-breaking aviator who piloted the Voyager aircraft around the world non-stop with co-pilot Jeana Yeager.  He was born in Loma Linda, California, where he gained an interest in flight at a young age.  He is the older brother of aerospace designer Burt Rutan.
