Answer the following question: Information: - In politics and military planning, a war effort refers to a coordinated mobilization of society's resourcesboth industrial and humantowards the support of a military force. Depending on the militarization of the culture, the relative size of the armed forces and the society supporting them, the style of government, and the popular support for the military objectives, such war effort can range from a small industry to complete command of society. - The National Security Act of 1947 was a major restructuring of the United States government's military and intelligence agencies following World War II. The majority of the provisions of the Act took effect on September 18, 1947, the day after the Senate confirmed James Forrestal as the first Secretary of Defense. - The Army Ground Forces were one of the three autonomous components of the Army of the United States during World War II, the others being the Army Air Forces and Army Service Forces. Throughout their existence, Army Ground Forces were the largest training organization ever established in the United States. Its strength of 780,000 troops on 1 May 1942 grew to a peak of 2,200,000 by 1 July 1943. Thereafter its strength declined as units departed for overseas theaters. - A reconnaissance aircraft is a manned or unmanned military aircraft designed, or adapted, to carry out aerial reconnaissance. Their roles are to collect imagery intelligence, signals intelligence, and measurement and signature intelligence. - A great power is a sovereign state that is recognized as having the ability and expertise to exert its influence on a global scale. Great powers characteristically possess military and economic strength, as well as diplomatic and soft power influence, which may cause middle or small powers to consider the great powers' opinions before taking actions of their own. International relations theorists have posited that great power status can be characterized into power capabilities, spatial aspects, and status dimensions. - Air cargo is any property carried or to be carried in an aircraft. Air cargo comprises air freight, air express and airmail. - 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. - The Code of Laws of the United States of America (variously abbreviated to Code of Laws of the United States, United States Code, U.S. Code, or U.S.C.) is the official compilation and codification of the general and permanent federal statutes of the United States. It contains 52 titles, and a further three titles have been proposed. The main edition is published every six years by the Office of the Law Revision Counsel of the House of Representatives, and cumulative supplements are published annually. The official version of those laws not codified in the United States Code can be found in United States Statutes at Large. - An airlift is the organized delivery of military supplies or military personnel primarily via military transport aircraft. - Military aviation is the use of military aircraft and other flying machines for the purposes of conducting or enabling aerial warfare, including national airlift (air cargo) capacity to provide logistical supply to forces stationed in a theater or along a front. Airpower includes the national means of conducting such warfare, including the intersection of transport and war craft. Military aircraft include bombers, fighters, transports, trainer aircraft, and reconnaissance aircraft. - The Congress of the Confederation, or the Confederation Congress, formally referred to as the United States in Congress Assembled, was the governing body of the United States of America that existed from March 1, 1781, to March 4, 1789. It comprised delegates appointed by the legislatures or assemblies of the several states. It was preceded by the Second Continental Congress (17751781) and governed under the newly adopted "Articles of Confederation and Perpetual Union", which were proposed 17761777, adopted by the Continental Congress in July 1778 and finally agreed to by a unanimous vote of all thirteen states by 1781, held up by a long dispute over the cession of western territories beyond the Appalachian Mountains to the central government led by Maryland and a coalition of smaller states without western claims. The newly reorganized Congress at the time continued to refer itself as the Continental Congress throughout its eight-year history, although modern historians separate it from the earlier bodies, which operated under slightly different rules and procedures until the later part of American Revolutionary War. The membership of the Second Continental Congress automatically carried over to the Congress of the Confederation when the latter was created by the ratification of the Articles of Confederation. It had the same secretary as the Second Continental Congress, namely Charles Thomson. The Congress of the Confederation was succeeded by the Congress of the United States as provided for in the Constitution of the United States, proposed September 17, 1787, in Philadelphia and ratified by the states through 1787 to 1788 and even into 1789 and 1790. - In military operations, reconnaissance is the exploration outside an area occupied by friendly forces to gain information about natural features and enemy presence. - Aeronautics (from the ancient Greek words "r", which means "air", and "nautik" which means "navigation", i.e. "navigation into the air") is the science or art involved with the study, design, and manufacturing of air flight capable machines, and the techniques of operating aircraft and rockets within the atmosphere. The British Royal Aeronautical Society identifies the aspects of "aeronautical Art, Science and Engineering" and "the profession of Aeronautics (which expression includes Astronautics)." - During World War II, the American atomic bombings of Hiroshima and Nagasaki made Nagasaki the second and, to date, last city in the world to experience a nuclear attack. - The Air Service, United States Army (also known as the ""Air Service"", ""U.S. Air Service"" and after its legislative establishment in 1920, the ""U.S. Army Air Service"") was the military aviation service of the United States between 1918 and 1926 and a forerunner of the United States Air Force. It was established as an independent but temporary branch of the U.S. War Department during World War I by two executive orders of President Woodrow Wilson: on May 24, 1918, replacing the Aviation Section, Signal Corps as the nation's air force; and March 19, 1919, establishing a military Director of Air Service to control all aviation activities. Its life was extended for another year in July 1919, during which time Congress passed the legislation necessary to make it a permanent establishment. The National Defense Act of 1920 assigned the Air Service the status of "combatant arm of the line" of the United States Army with a major general in command. - The Continental Army was formed by the Second Continental Congress after the outbreak of the American Revolutionary War by the colonies that became the United States of America. Established by a resolution of the Congress on June 14, 1775, it was created to coordinate the military efforts of the Thirteen Colonies in their revolt against the rule of Great Britain. The Continental Army was supplemented by local militias and troops that remained under control of the individual states or were otherwise independent. General George Washington was the commander-in-chief of the army throughout the war. - Aerial warfare is the use of military aircraft and other flying machines in warfare. Aerial warfare includes bombers attacking enemy concentrations or strategic targets; fighter aircraft battling for control of airspace; attack aircraft engaging in close air support against ground targets; naval aviation flying against sea and nearby land targets; gliders, helicopters and other aircraft to carry airborne forces such as paratroopers; aerial refueling tankers to extend operation time or range; and military transport aircraft to move cargo and personnel. Historically, military aircraft have included lighter-than-air balloons carrying artillery observers; lighter-than-air airships for bombing cities; various sorts of reconnaissance, surveillance and early warning aircraft carrying observers, cameras and radar equipment; torpedo bombers to attack enemy shipping; and military air-sea rescue aircraft for saving downed airmen. Modern aerial warfare includes missiles and unmanned aerial vehicles. Surface forces are likely to respond to enemy air activity with anti-aircraft warfare. - World War I (WWI or WW1), also known as the First World War, or the Great War, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. More than 70million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history. Over nine million combatants and seven million civilians died as a result of the war (including the victims of a number of genocides), a casualty rate exacerbated by the belligerents' technological and industrial sophistication, and the tactical stalemate caused by gruelling trench warfare. It was one of the deadliest conflicts in history, and paved the way for major political changes, including revolutions in many of the nations involved. - A military alliance is an international agreement concerning national security, when the contracting parties promise to support each other in case of a crisis that has not been identified in advance. Military alliances differ from coalitions, as coalitions are formed for a crisis that are already known. - Hiroshima is perhaps best known as the first city in history to be targeted by a nuclear weapon when the United States Army Air Forces (USAAF) dropped an atomic bomb on the city (and later on Nagasaki) at 8:15a.m. on August 6, 1945, near the end of World War II. - A military aircraft is any fixed-wing or rotary-wing aircraft that is operated by a legal or insurrectionary armed service of any type. Military aircraft can be either combat or non-combat: - The Army of the United States or Armies of the United States is the legal name of the "land forces of the United States" (United States Constitution, Article 2, Section 2, Clause 1 and United States Code, Title 10, Subtitle B, Chapter 301, Section 3001) and has been used in this context since at least 1841, as in the title: "General Regulations for the Army of the United States". The Army, or Armies of the United States includes: the Regular Army, Army National Guard, and the Army Reserve, (as well as any volunteer or conscripted forces). - The United States Armed Forces are the federal armed forces of the United States. They consist of the Army, Marine Corps, Navy, Air Force, and Coast Guard. The President of the United States is the military's overall head, and helps form military policy with the U.S. Department of Defense (DoD), a federal executive department, acting as the principal organ by which military policy is carried out. From the time of its inception, the military played a decisive role in the history of the United States. A sense of national unity and identity was forged as a result of victory in the First Barbary War and the Second Barbary War. Even so, the Founders were suspicious of a permanent military force. It played an important role in the American Civil War, where leading generals on both sides were picked from members of the United States military. Not until the outbreak of World WarII did a large standing army become officially established. The National Security Act of 1947, adopted following World WarII and during the Cold War's onset, created the modern U.S. military framework; the Act merged previously Cabinet-level Department of War and the Department of the Navy into the National Military Establishment (renamed the Department of Defense in 1949), headed by the Secretary of Defense; and created the Department of the Air Force and National Security Council. - The Army Service Forces were one of the three autonomous components of the Army of the United States during World War II, the others being the Army Air Forces and Army Ground Forces. They were created on February 28, 1942 by Executive Order Number 9082 "Reorganizing the Army and the War Department" and War Department Circular No. 59, dated March 2, 1942. - The United States dropped nuclear weapons on the Japanese cities of Hiroshima and Nagasaki on August 6 and 9, 1945, respectively, during the final stage of World War II. The United States had dropped the bombs with the consent of the United Kingdom as outlined in the Quebec Agreement. The two bombings, which killed at least 129,000 people, remain the only use of nuclear weapons for warfare in history. - The United States Army Air Forces ( USAAF or AAF ) was the military aviation service of the United States of America during and immediately after World War II , successor to the United States Army Air Corps and the direct predecessor of the United States Air Force . The AAF were a component of the United States Army , which in 1942 was divided functionally by executive order into three autonomous forces : the Army Ground Forces , the Services of Supply ( which in 1943 became the Army Service Forces ) , and the Army Air Forces . Each of these forces had a commanding general who reported directly to the Army Chief of Staff . The AAF administered all parts of military aviation formerly distributed among the Air Corps , General Headquarters Air Force , and the ground forces ' corps area commanders , and thus became the first air organization of the U.S. Army to control its own installations and support personnel . The peak size of the AAF during the Second World War was over 2.4 million men and women in service and nearly 80,000 aircraft by 1944 , and 783 domestic bases in December 1943 . By '' V - E Day '' , the Army Air Forces had 1.25 million men stationed overseas and operated from more than 1,600 airfields worldwide . The Army Air Forces were created in June 1941 to provide the air arm a greater autonomy in which to expand more efficiently , to provide a structure for the additional command echelons required by a vastly increased force , and to end an increasingly divisive administrative battle within the Army over control of aviation doctrine and organization that had been ongoing since the creation of an aviation section within the Army Signal Corps in 1914 . The AAF succeeded both the Air Corps , which had been the statutory military aviation branch since 1926 , and the GHQ Air Force , which had been activated in 1935 to quiet the demands of airmen for an independent Air Force . Although other nations already had separate air forces independent of their army or navy ( such as the British Royal Air Force... - The United States Army (USA) is the largest branch of the United States Armed Forces and performs land-based military operations. It is one of the seven uniformed services of the United States and is designated as the Army of the United States in the United States Constitution, Article 2, Section 2, Clause 1 and United States Code, Title 10, Subtitle B, Chapter 301, Section 3001. As the largest and senior branch of the U.S. military, the modern U.S. Army has its roots in the Continental Army, which was formed (14 June 1775) to fight the American Revolutionary War (17751783)before the U.S. was established as a country. After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784, to replace the disbanded Continental Army. The United States Army considers itself descended from the Continental Army, and dates its institutional inception from the origin of that armed force in 1775. - Strategic bombing is a military strategy used in a total war with the goal of defeating the enemy by destroying its morale or its economic ability to produce and transport materiel to the theatres of military operations, or both. It is a systematically organized and executed attack from the air which can utilize strategic bombers, long- or medium-range missiles, or nuclear-armed fighter-bomber aircraft to attack targets deemed vital to the enemy's war-making capability. - Total war is warfare that includes any and all civilian-associated resources and infrastructure as legitimate military targets, mobilizes all of the resources of society to fight the war, and gives priority to warfare over non-combatant needs. The American-English Dictionary defines total war as "war that is unrestricted in terms of the weapons used, the territory or combatants involved, or the objectives pursued, especially one in which the laws of war are disregarded." - The Holocaust (from the Greek ': "holos", "whole" and "kaustos", "burnt"), also referred to as the Shoah"' (Hebrew: , "HaShoah", "the catastrophe"), was a genocide in which Adolf Hitler's Nazi Germany and its collaborators killed about six million Jews. The victims included 1.5million children and represented about two-thirds of the nine million Jews who had resided in Europe. Some definitions of the Holocaust include the additional five million non-Jewish victims of Nazi mass murders, bringing the total to about 11 million. Killings took place throughout Nazi Germany, German-occupied territories, and territories held by allies of Nazi Germany. - A bomber is a combat aircraft designed to attack ground and sea targets by dropping air-to-ground weaponry, firing torpedoes or deploying air-launched cruise missiles. - Combat arms (or fighting arms in non-American parlance) is a collective name in a system of administrative military reference to those troops within national armed forces which participate in direct tactical ground combat. In general they include units that carry or employ a weapon system such as infantry, cavalry, and artillery units. The use of multiple combat arms in mutually supporting ways is known as combined arms. - The United States Air Force (USAF) is the aerial 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 military on 18 September 1947 under the National Security Act of 1947. It is the most recent branch of the U.S. military to be formed, and is the largest and one of the world's most technologically advanced air forces. The USAF articulates its core functions as Nuclear Deterrence Operations, Special Operations, Air Superiority, Global Integrated ISR, Space Superiority, Command and Control, Cyberspace Superiority, Personnel Recovery, Global Precision Attack, Building Partnerships, Rapid Global Mobility and Agile Combat Support. - Airpower or air power comprises the application of military strategy and strategic theory to the realm of aerial warfare. Airpower began with the advent of powered flight early in the 20th century. Airpower represents a "complex operating environment that has been subjected to considerable debate". British doctrine defines airpower as "the ability to project power from the air and space to influence the behaviour of people or the course of events." - Aviation is the practical aspect or art of aeronautics, being the design, development, production, operation and use of aircraft, especially heavier than air aircraft. The word "aviation" was coined by French writer and former naval officer Gabriel La Landelle in 1863, from the verb "avier" (synonymous flying), itself derived from the Latin word "avis" ("bird") and the suffix "-ation". - The United States Army Air Corps (USAAC) was the military aviation arm of the United States of America between 1926 and 1941. The statutory administrative forerunner of the United States Air Force, it was renamed from the earlier United States Army Air Service on 2 July 1926 and part of the larger United States Army. The Air Corps was the immediate predecessor of the United States Army Air Forces (USAAF), established on 20 June 1941. Although discontinued as an administrative echelon during World War II, the Air Corps (AC) remained as one of the combat arms of the Army until 1947, when it was legally abolished by legislation establishing the Department of the Air Force. - The American Revolutionary War (17751783), also referred to as the American War of Independence and the Revolutionary War in the United States, was an armed conflict between Great Britain and thirteen of its North American colonies that after onset of the war declared independence as the United States of America.
