Military logistics is the discipline of planning and carrying out the movement, supply, and maintenance of military forces. In its most comprehensive sense, it is those aspects or military operations that deal with:
109-610: The Royal Logistic Corps provides logistic support functions to the British Army . It is the largest Corps in the Army. The Royal Logistic Corps (RLC) was formed on 5 April 1993, by the union of five British Army corps: The RLC comprises both Regular and Army Reserve units. The RLC is the only combat service support corps of the British Army with battle honours , derived from the usage of previous transport elements of
218-659: A Neutrality Pact in April 1941, and Japan adopted the doctrine of Nanshin-ron , promoted by the Navy, which took its focus southward and eventually led to war with the United States and the Western Allies. In Europe, Germany and Italy were becoming more aggressive. In March 1938, Germany annexed Austria , again provoking little response from other European powers. Encouraged, Hitler began pressing German claims on
327-578: A cautious French probe into the Saarland . The Western Allies also began a naval blockade of Germany , which aimed to damage the country's economy and war effort. Germany responded by ordering U-boat warfare against Allied merchant and warships, which would later escalate into the Battle of the Atlantic . On 8 September, German troops reached the suburbs of Warsaw . The Polish counter-offensive to
436-817: A campaign, and all orders of march and other orders from the general-in-chief relative to moving and supplying armies. The term became popularised during the Second World War . In Logistics in World War II: Final Report of the Army Service Forces , Lieutenant General LeRoy Lutes , the commanding general of the Army Service Forces , gave the term a more expansive definition: The word "logistics" has been given many different shades of meaning. A common definition is: "That branch of military art which embraces
545-445: A form of economic warfare . A besieging force can attempt to starve out a garrison or tempt it to sally through devastation of the surrounding area rather than undertake the more costly operation of assaulting and destroying it, but if it is dependent on local supply then the besieger who might be starved out through their exhaustion. A second method is to bring along what is needed, whether by ships, pack animals, wagons or carried on
654-524: A pretext to initiate the invasion. The first German attack of the war came against the Polish defences at Westerplatte . The United Kingdom responded with an ultimatum for Germany to cease military operations, and on 3 September, after the ultimatum was ignored, Britain and France declared war on Germany. During the Phoney War period, the alliance provided no direct military support to Poland, outside of
763-781: A pretext to worsen relations. On 29 August, Hitler demanded that a Polish plenipotentiary immediately travel to Berlin to negotiate the handover of Danzig , and to allow a plebiscite in the Polish Corridor in which the German minority would vote on secession. The Poles refused to comply with the German demands, and on the night of 30–31 August in a confrontational meeting with the British ambassador Nevile Henderson , Ribbentrop declared that Germany considered its claims rejected. On 1 September 1939, Germany invaded Poland after having staged several false flag border incidents as
872-475: A secret protocol that defined German and Soviet "spheres of influence" (western Poland and Lithuania for Germany; eastern Poland , Finland, Estonia , Latvia and Bessarabia for the Soviet Union), and raised the question of continuing Polish independence. The pact neutralised the possibility of Soviet opposition to a campaign against Poland and assured that Germany would not have to face the prospect of
981-774: A similar pact and rejected ceding part of its territory to the Soviet Union. The Soviet Union invaded Finland in November 1939, and was subsequently expelled from the League of Nations for this crime of aggression. Despite overwhelming numerical superiority, Soviet military success during the Winter War was modest, and the Finno-Soviet war ended in March 1940 with some Finnish concessions of territory . In June 1940,
1090-447: A town and one coming to its relief. Unless a commander was able to arrange a form of regular resupply, a fortress or town with a devastated countryside could become immune to either operation. Napoleon made logistics a major part of his strategy. He dispersed his corps along a broad front to maximise the area from which supplies could be drawn. Each day forage parties brought in supplies. This differed from earlier operations living off
1199-531: A two-front war, as it had in World War I. Immediately afterwards, Hitler ordered the attack to proceed on 26 August, but upon hearing that the United Kingdom had concluded a formal mutual assistance pact with Poland and that Italy would maintain neutrality, he decided to delay it. In response to British requests for direct negotiations to avoid war, Germany made demands on Poland, which served as

It is possible to capture supplies from the enemy or enemy population. An alternative is purchasing , whereby an army takes cash and buys its supplies in the field. Cash can also be obtained in the field through local taxation, backed by

Col RLC is responsible for the Moral Component, regimental infrastructure and support and works to Commander Home Command. Col RLC remains responsible for the Corps of Drums , which often parades with the RLC Band. (AG). The RLC Band was formed in 1993. It provides musical support while also representing the Royal Logistic Corps, and on occasion,
1526-440: Is more restricted than the military definition. Logistics is an enabler of military operations, not an end in itself. Poor logistics can result in defeat, but even the best logistics cannot guarantee victory. Conversely, the best possible logistics is not always required: fit for purpose can suffice. Historian James A. Huston proposed sixteen principles of military logistics: The United States Joint Chiefs of Staff reduced
1635-506: Is required for planning by the medical services. Mathematical models of combat have been developed for this purpose. Lanchester's laws are differential equations that describe the time dependence of two armies' strengths as a function of time. Mathematical models exist for scheduling of convoys to ensure that vehicles and the goods they carry arrive in time. Vehicle routing models can be used to select routes for timely delivery with minimum exposure to enemy action and without overloading
1744-461: Is the dominant concern. The development of computers facilitated the use of analytic tools. Multiple-criteria decision analysis (MCDA) is a sub-discipline of operations research that explicitly evaluates multiple conflicting criteria in decision making. The location of a supply depot could involve multiple considerations and constraints, such as the access to road, rail and sea transport, and travel times to desired delivery destinations. Sometimes
1853-604: The Anglo-German Naval Agreement and the German–Polish declaration of non-aggression . The situation became a crisis in late August as German troops continued to mobilise against the Polish border. On 23 August the Soviet Union signed a non-aggression pact with Germany, after tripartite negotiations for a military alliance between France, the United Kingdom, and Soviet Union had stalled. This pact had

Through a series of campaigns and treaties, Germany took control of much of continental Europe and formed the Axis alliance with Italy , Japan , and other countries. In June 1941, Germany led the European Axis in an invasion of
2071-555: The Department of Defense call this methodology the Analysis of Alternatives , and require it for military acquisitions. Logistical planning requires forecasting of future consumption and attrition. There are two types of attrition: material attrition and personnel attrition. The former relates to the loss of equipment through combat, accidents and ordinary wear and tear through usage. Reliability theory can be used to forecast
2180-581: The German Revolution of 1918–1919 , and a democratic government, later known as the Weimar Republic , was created. The interwar period saw strife between supporters of the new republic and hardline opponents on both the political right and left. Italy, as an Entente ally, had made some post-war territorial gains; however, Italian nationalists were angered that the promises made by the United Kingdom and France to secure Italian entrance into
2289-853: The German invasion of Poland and the United Kingdom and France 's declaration of war on Germany two days later on 3 September 1939. Dates for the beginning of the Pacific War include the start of the Second Sino-Japanese War on 7 July 1937, or the earlier Japanese invasion of Manchuria , on 19 September 1931. Others follow the British historian A. J. P. Taylor , who stated that the Sino-Japanese War and war in Europe and its colonies occurred simultaneously, and

Food, water and fodder for the animals could usually be found or purchased in the field. The Roman Empire built networks of roads, but it was far less expensive to transport a ton of grain from Egypt to Rome by sea than 80 kilometres (50 mi) by road. After the fall of

The war in Europe concluded with the liberation of German-occupied territories ; the invasion of Germany by the Western Allies and the Soviet Union, culminating in the fall of Berlin to Soviet troops; Hitler's suicide ; and the German unconditional surrender on 8 May 1945 . Following the refusal of Japan to surrender on the terms of the Potsdam Declaration ,
2725-695: The League of Nations as a force to preserve peace. Both Italy and Ethiopia were member nations, but the League did little when the former clearly violated Article X of the League's Covenant . The United Kingdom and France supported imposing sanctions on Italy for the invasion, but the sanctions were not fully enforced and failed to end the Italian invasion. Italy subsequently dropped its objections to Germany's goal of absorbing Austria . When civil war broke out in Spain, Hitler and Mussolini lent military support to
2834-731: The Nationalist rebels , led by General Francisco Franco . Italy supported the Nationalists to a greater extent than the Nazis: Mussolini sent more than 70,000 ground troops, 6,000 aviation personnel, and 720 aircraft to Spain. The Soviet Union supported the existing government of the Spanish Republic . More than 30,000 foreign volunteers, known as the International Brigades , also fought against

The Kuomintang (KMT) party in China launched a unification campaign against regional warlords and nominally unified China in the mid-1920s, but was soon embroiled in a civil war against its former Chinese Communist Party (CCP) allies and new regional warlords . In 1931, an increasingly militaristic Empire of Japan , which had long sought influence in China as
3052-553: The Second World War (1 September 1939 – 2 September 1945) was a global conflict between two coalitions: the Allies and the Axis powers . Nearly all the world's countries —including all the great powers —participated, with many investing all available economic, industrial, and scientific capabilities in pursuit of total war , blurring the distinction between military and civilian resources. Tanks and aircraft played major roles , with
3161-590: The Soviet–Japanese Neutrality Pact in April 1941. By contrast, the Germans were steadily making preparations for an attack on the Soviet Union, massing forces on the Soviet border. Hitler believed that the United Kingdom's refusal to end the war was based on the hope that the United States and the Soviet Union would enter the war against Germany sooner or later. On 31 July 1940, Hitler decided that
3270-598: The Stresa Front in April 1935 in order to contain Germany, a key step towards military globalisation ; however, that June, the United Kingdom made an independent naval agreement with Germany, easing prior restrictions. The Soviet Union, concerned by Germany's goals of capturing vast areas of Eastern Europe , drafted a treaty of mutual assistance with France. Before taking effect, though, the Franco-Soviet pact

Soon the United Kingdom and France followed the appeasement policy of British Prime Minister Neville Chamberlain and conceded this territory to Germany in the Munich Agreement , which was made against the wishes of the Czechoslovak government, in exchange for a promise of no further territorial demands. Soon afterwards, Germany and Italy forced Czechoslovakia to cede additional territory to Hungary, and Poland annexed

3597-579: The Trans-Olza region of Czechoslovakia. Although all of Germany's stated demands had been satisfied by the agreement, privately Hitler was furious that British interference had prevented him from seizing all of Czechoslovakia in one operation. In subsequent speeches Hitler attacked British and Jewish "war-mongers" and in January 1939 secretly ordered a major build-up of the German navy to challenge British naval supremacy. In March 1939, Germany invaded
3706-558: The Treaty of Craiova . The loss of one-third of Romania's 1939 territory caused a coup against King Carol II, turning Romania into a fascist dictatorship under Marshal Ion Antonescu , with a course set towards the Axis in the hopes of a German guarantee. Meanwhile, German-Soviet political relations and economic co-operation gradually stalled, and both states began preparations for war. In April 1940, Germany invaded Denmark and Norway to protect shipments of iron ore from Sweden , which
3815-749: The United Kingdom and France to declare war on Germany. Poland was divided between Germany and the Soviet Union under the Molotov–Ribbentrop Pact , in which they had agreed on " spheres of influence " in Eastern Europe. In 1940, the Soviets annexed the Baltic states and parts of Finland and Romania . After the fall of France in June 1940, the war continued mainly between Germany and

The United Kingdom was able to evacuate a significant number of Allied troops from the continent by early June, although they had to abandon almost all their equipment. On 10 June, Italy invaded France , declaring war on both France and

No formal peace treaty between Japan and the Soviet Union was ever signed, although the state of war between the two countries was terminated by the Soviet–Japanese Joint Declaration of 1956 , which also restored full diplomatic relations between them. World War I had radically altered

The Nationalists won the civil war in April 1939; Franco, now dictator, remained officially neutral during World War II but generally favoured the Axis . His greatest collaboration with Germany was the sending of volunteers to fight on the Eastern Front . In July 1937, Japan captured

In August 1940, Hitler imposed the Second Vienna Award on Romania which led to the transfer of Northern Transylvania to Hungary. In September 1940, Bulgaria demanded Southern Dobruja from Romania with German and Italian support, leading to
5886-421: The Soviet Union , opening the Eastern Front and initially making large territorial gains. Japan aimed to dominate East Asia and the Asia-Pacific , and by 1937 was at war with the Republic of China . In December 1941, Japan attacked American and British territories in Southeast Asia and the Central Pacific , including Pearl Harbor in Hawaii , which resulted in the US and the UK declaring war against Japan, and
5995-418: The Soviet Union and Mongolia . The Japanese doctrine of Hokushin-ron , which emphasised Japan's expansion northward, was favoured by the Imperial Army during this time. This policy would prove difficult to maintain in light of the Japanese defeat at Khalkin Gol in 1939, the ongoing Second Sino-Japanese War and ally Nazi Germany pursuing neutrality with the Soviets. Japan and the Soviet Union eventually signed
6104-575: The Soviet Union should be eliminated and aimed for the conquest of Ukraine , the Baltic states and Byelorussia . However, other senior German officials like Ribbentrop saw an opportunity to create a Euro-Asian bloc against the British Empire by inviting the Soviet Union into the Tripartite Pact. In November 1940, negotiations took place to determine if the Soviet Union would join the pact. The Soviets showed some interest but asked for concessions from Finland, Bulgaria, Turkey, and Japan that Germany considered unacceptable. On 18 December 1940, Hitler issued
6213-402: The US dropped the first atomic bombs on Hiroshima and Nagasaki on 6 and 9 August. Faced with an imminent invasion of the Japanese archipelago , the possibility of further atomic bombings, and the Soviet declaration of war against Japan and its invasion of Manchuria , Japan announced its unconditional surrender on 15 August and signed a surrender document on 2 September 1945 , marking

Shortly after the Franco - British pledge to Poland, Germany and Italy formalised their own alliance with the Pact of Steel . Hitler accused the United Kingdom and Poland of trying to "encircle" Germany and renounced

Animals could be driven to accompany the army and consumed for meat. Roads facilitate the movement of wheeled vehicles, and travel by river or sea permits the carriage of large volumes of supplies. This allowed the army some measure of self-sufficiency, and until

The most basic requirements of an army were food and water. Early armies were equipped with weapons used for hunting like spears, knives, axes and bows and arrows, and rarely exceeded 20,000 men due to the practical difficulty of supplying a large number of soldiers.

The organisation's primary goals were to prevent armed conflict through collective security, military, and naval disarmament , as well as settling international disputes through peaceful negotiations and arbitration. Despite strong pacifist sentiment after World War I , irredentist and revanchist nationalism had emerged in several European states. These sentiments were especially marked in Germany because of

World War II changed the political alignment and social structure of the world, and it set the foundation of international relations for the rest of the 20th century and into the 21st century. The United Nations was established to foster international cooperation and prevent conflicts, with the victorious great powers—China, France, the Soviet Union, the UK, and the US—becoming

However, with the increase in army sizes from the late sixteenth century onward, this reliance on pillage and plunder became problematic, as decisions regarding where and when an army could move or fight became based not on strategic objectives but on whether a given area was capable of supporting the soldiers' needs. Sieges in particular were affected by this, both for an army attempting to lay siege to

From September to November, the Japanese attacked Taiyuan , engaged the Kuomintang Army around Xinkou , and fought Communist forces in Pingxingguan . Generalissimo Chiang Kai-shek deployed his best army to defend Shanghai , but after three months of fighting, Shanghai fell. The Japanese continued to push Chinese forces back, capturing
8611-438: The heavier weight of shells and bombs made it more difficult for armies to carry their requirements, and they soon became dependent on regular replenishment of ammunition from depots. At the same time, mechanisation, with motor vehicles replacing animals, created a demand for fuel and spare parts, neither of which could be obtained locally.

This
9156-408: The number of alternatives is small and they can be considered individually, but they can also be too large for this to be possible. The consideration of constraints simplifies the decision making. These constraints could be economic, such as cost, but might also be less easily quantified, such as political, strategic or operational considerations. The United States Office of Management and Budget and
9265-427: The number of principles to just seven: There are three basic options for the supply of an army in the field, which can be employed individually or in combination. The most basic requirements of an army were food and water. Foraging involved gathering food and fodder for animals in the field. The availability of these tends to be seasonal, with greater abundance around harvest time in agricultural regions. There
9374-502: The permanent members of its security council . The Soviet Union and the United States emerged as rival superpowers , setting the stage for the Cold War . In the wake of European devastation, the influence of its great powers waned, triggering the decolonisation of Africa and Asia .

9919-605: The railhead, although many armies still used animals during the Second World War . The development of air transport provided an alternative to both land and sea transport, but with limited tonnage and at high cost. An airlift over " the Hump " helped supply the Chinese war effort , and after the war the 1948 Berlin Air Lift was successful in supplying half of the city. With the subsequent development of large jets, aircraft became
10028-463: The rear. Canning simplified storage and distribution of foods, and reduced waste and the incidence of food-related illness. Refrigeration allowed frozen meat and fresh produce to be stored and shipped. Steamships made water transports faster and more reliable.

10573-441: The threat of violence. The major drawback of using local sources of supply is that they can be exhausted if an army remains in one place for too long, so a force dependent on local supply needs to keep moving. The widespread use of resources in the field gives rise to counter-logistics, whereby they are denied to the enemy through devastation of the land and removal or destruction of resources. Pre-emptive purchasing can be used as
10682-518: The two wars became World War II in 1941. Other proposed starting dates for World War II include the Italian invasion of Abyssinia on 3 October 1935.

To assist Italy and prevent Britain from gaining a foothold, Germany prepared to invade the Balkans, which would threaten Romanian oil fields and strike against British dominance of the Mediterranean. In December 1940, British Empire forces began counter-offensives against Italian forces in Egypt and Italian East Africa . The offensives were successful; by early February 1941, Italy had lost control of eastern Libya, and large numbers of Italian troops had been taken prisoner. The Italian Navy also suffered significant defeats, with
11881-673: Was required to go through the bureaucracy of the League of Nations, which rendered it essentially toothless.
