Abstract During the recent war a great part of the military operations were conducted in warm, humid, tropical regions, ideal for the growth of fungi. The protection of the cotton cloth used in rubber-coated fabrics thus became a major problem of the armed forces. Because the area was of minor importance in the world consumer market, comparatively little work had been done on this problem by the research laboratories of private industry. A tropical testing chamber which simulated tropical conditions was built at Fort Belvoir to study the problems of fungus growth and effective countermeasures. The problem was complicated by the possibility that the fungicide which had a protective effect on the cloth might have had a destructive effect on the rubber coating. Tests on pentachlorophenol and 2,2′-methylene-bis (4-chlorophenol) by two industrial concerns had indicated that these two fungicides had no adverse effect on either natural rubber or GR-S when used in small concentrations. Tests by another industrial concern had indicated that salicylanilide was satisfactory for use with natural rubber and Neoprene. However, because of the meager amount of information available, a study was conducted to determine what fungicides, and in what concentrations, might abnormally deteriorate rubber coatings.

AbstractLeishmaniasis is an infectious disease caused by Leishmania protozoa, transmitted by the bite of phlebotomine sandflies. It causes a spectrum of clinical syndromes, of which the most common are cutaneous and visceral leishmaniasis. Clinical presentation is highly variable and is dependent on multiple factors, such as Leishmania species and patient characteristics (including immune competence). The relationship between these variables is poorly understood, and there is no single, evidence-based treatment for the disease. Currently management focuses on identification of the species, but this requires specialist tests which are often unavailable, particularly on military operations. Leishmaniasis is of particular relevance to military medical personnel as it is endemic in many tropical and sub-tropical regions of the world, including Belize, Iraq and Afghanistan where UK Armed Forces may be deployed. It can present a potentially serious threat to military personnel deployed in endemic areas due to the possibility of long-term sequelae of infection.

World War II has called forth greater organizational and administrative efforts than ever before on the part of the armed forces, private industry, and government. The sheer size of the new organizations that were formed to fight battles, manufacture matériel, and administer government programs has intensified the problems of top management and executive control, as well as the technical problems of military operations, supply, and industrial production. Great dynamic changes in society always afford occasion for reappraising basic philosophies, and these significant changes in the scope and scale of our great enterprises are no exception. The field of management is perhaps less spectacular, less open to popular discussion than are the issues of foreign policy and of government participation in the national economy. But effective management of our enterprise is of fundamental importance to a successful conclusion of the war and subsequent maintenance of peace. The demands of the war on the home front have stimulated much re-thinking of the theories of government and business administration. This article is concerned with the relation between the basic theories of two of the greatest contributors to the field of management—Frederick Taylor and Henri Fayol.We all know what the task of organizing for war has been during the past four years. Arms production of undreamed of magnitude had to be developed in a matter of months. To produce the vast number of planes, tanks, and ships, new enterprises sprang up over night and existing ones expanded to many times their original size. Similarly, the federal government, in addition to creating tremendous staffs in the War and Navy Departments, had to develop quickly “administrative leviathans” to control prices and ration goods, allocate industrial production, and direct the production and distribution of foods. War-time control had to be exercised to an unprecedented degree, frequently for hitherto unregulated matters, in connection with oil, censorship, transportation, manpower, and the like. Besides a need for more technical personnel in industrial production, there developed a need for people able to organize and direct large new enterprises.


The armed forces of Europe have undergone a dramatic transformation since the collapse of the Soviet Union. The Handbook of European Defence Policies and Armed Forces provides the first comprehensive analysis of national security and defence policies, strategies, doctrines, capabilities, and military operations, as well as the alliances and partnerships of European armed forces in response to the security challenges Europe has faced since the end of the cold war. A truly cross-European comparison of the evolution of national defence policies and armed forces remains a notable blind spot in the existing literature. This Handbook aims to fill this gap with fifty-one contributions on European defence and international security from around the world. The six parts focus on: country-based assessments of the evolution of the national defence policies of Europe’s major, medium, and lesser powers since the end of the cold war; the alliances and security partnerships developed by European states to cooperate in the provision of national security; the security challenges faced by European states and their armed forces, ranging from interstate through intra-state and transnational; the national security strategies and doctrines developed in response to these challenges; the military capabilities, and the underlying defence and technological industrial base, brought to bear to support national strategies and doctrines; and, finally, the national or multilateral military operations by European armed forces. The contributions to The Handbook collectively demonstrate the fruitfulness of giving analytical precedence back to the comparative study of national defence policies and armed forces across Europe.

The National Security Council, created by the National Security Act of 1947, is the instrument through which the President obtains the collective advice of the appropriate officials of the executive branch concerning the integration of domestic, foreign, and military policies relating to the national security. An outline of the genesis of this new governmental agency will indicate in part its present rôle.Even before World War II, a few far-sighted men were seeking for a means of correlating our foreign policy with our military and economic capabilities. During the war, as military operations began to have an increasing political and economic effect, the pressure for such a correlation increased. It became apparent that the conduct of the war involved more than a purely military campaign to defeat the enemy's armed forces. Questions arose of war aims, of occupational policies, of relations with governments-in-exile and former enemy states, of the postwar international situation with its implications for our security, and of complicated international machinery.


Significance The closure of border crossings since March 2020 has fuelled violent competition for control of lucrative informal crossings (trochas) and frontier towns. However, the Venezuelan military is ill-prepared to deal with the expanding presence of Colombia’s irregular armed groups. Recent incursions highlight weaknesses in the Venezuelan armed forces, which have suffered casualties. Impacts The penetration of organised crime groups into Venezuela’s disintegrating state and economy will continue to intensify. Organised criminal violence coupled with the violence of military operations will fuel displacement, COVID and civilian casualties. A speedy, negotiated solution to Venezuela’s political impasse is needed to preclude fusion with Colombia’s own protracted insurgency.

We know that the strategy must create the basic knowledge that links both the ways and the means to achieve the desired political goals and strategic results. This logical method is a continuous thought process that provides strategic intent and informs ways, creating links to strategic planning that lead to the use of means, in military operations. This factor is the element that includes calculating, sleight and creating a logic or chain of results in strategy. In this paper, after considering a strategy distillation, we will analyze the context of hybrid warfare in strategic planning, which is of particular concern to us in Greek-Turkish relations.

The article presents the attempts of Polish coast defenders’ to get through to neutral countries by sea during military operations in September and October 1939. These efforts were made in spite of the German blockade of Polish coast by Kriegsmarine ships and Luftwaffe planes. This subject hasn’t been widely featured yet using the reports of coast defenders kept in Polish and foreign archives. The goal of this article is the systematization of knowledge about these facts, presentation of characters of sailors, soldiers and civilians, who didn’t want to go into captivity. Some of them were going to continue their struggle in Polish Armed Forces in the West.

At the current stage of the reformation of the Armed Forces of Ukraine in the context of the operation of the United Nations (Anti-Terrorist Operation (ATO)), there was a need to increase the effectiveness of the use of troops without increasing the cost of the resource. In the context of increasing capabilities of the armies of the leading countries in the world to investigate and defeat the forces of the opposite side, the problem of maintaining and restoring combat capability in the course of hostilities is very acute. One of the important components that determines combat capability is the maneuverability of the control points (PU). In the course of the defense, the problem of increasing the survivability of the PU system is important because the forces of the opposite side, with the onset of aggression, will try, first of all, to dismantle the PU using modern means of defeat and the massive use of high-precision weapons (WTZ), as well as aircraft and artillery strikes, electronic information and information fight, the use of sabotage and reconnaissance groups and tactical airborne troops to disrupt the control of defending troops. Important importance of the ability to timely carry out maneuver (organized movement) of PU and its elements into a new area in the preparation and in the course of military operations. The traditional approach to ensuring the survivability of PU does not allow to ensure the proper stability of their functioning. There is an objective necessity in the development of such a mathematical model of maneuverability, which in its characteristics would meet the dynamically increasing requirements of the control system of troops in the difficult conditions of projected operations. To ensure the quality management of military units, various measures to ensure the survivability of PU are considered. The article outlines approaches to the definition of indicators of estimation of maneuverability of PU and methods of their calculation. The research is carried out in modern conditions of combat operations, taking into account the movement of the line of the combat collision of the parties and the disclosure of the PU to the enemy's intelligence.

Military impact on the environment can be defined as two components: 1) impact on the environment in time of daily activities during the training of troops and 2) impact on the environment during the combat operation. In the Armed Forces of Ukraine, to some extent, environmental security measures are implemented only during daily operations in peacetime. As for taking into account the impact of fighting on the environment in time of planning combat operations, this issue is usually not even raised in their preparation. On the other hand, NATO member states understand that military operations can be inherently destructive to human health and the environment. Therefore, this study was conducted to determine the educational requirements for commanders, especially for officers who provide environmental protection in the Armed Forces of Ukraine, based on NATO regulations and the experience of Allies. The article considers how environmental issues are integrated into the military operation at each stage: planning, pre-deployment, deployment (execution and force rotation), redeployment, and post-deployment. The main tasks of environmental officers at each stage of the operation are defined. Based on the tasks solved by officers, the requirements for their education are formed, the subjects studied by US environmental officers are considered.

This chapter examines debates over US policy in the summer of 2006, focusing particularly on the unhappy results of military efforts to tamp down violence in Baghdad. Two major military operations—Operations Together Forward I and II—were launched, intended, as the chairman of the Joint Chiefs of Staff, Peter Pace, recalled, to “begin the process of turning over the battlefield responsibilities to the Iraqi armed forces.” Both were clear disappointments, however, revealing how unprepared Iraqi forces were to assume responsibility for their country's security. Iraqi forces themselves were, in the words of the National Security Council's Meghan O'Sullivan, “perpetuating acts of sectarian violence” and were “as much part of the problem as they are a solution to the problem.” Throughout the summer, NSC staff thus sought to press the Iraq country team for a review of Iraq strategy, and pushed the president to ask General George Casey, commander of Multi-National Force Iraq (MNF-I), harder questions about where the current approach was leading. However, MNF-I and the US Embassy in Iraq continued to champion existing plans, believing that the existing strategy merely required more time.
