The Impact

Radar is a ground defense system that detects enemy aircraft and receives power from a mobile power supply in an emergency. Serious problems may occur if the equipment is damaged by impact during transportation for use. The US military standard MIL-STD-810H contains information on environmental tests such as shock and vibration applied to munitions. Therefore, in this study, the transient analysis of ANSYS 19.2 was performed using the impact data specified in MIL-STD-810H as an input value. Through this, the maximum stress generated in the impact environment of the mobile power supply container was derived, and the safety margin was calculated to confirm the reliability of the container.

Unit Cohesion

Abstract Recent political debates over the inclusion of transgender servicemembers in the US military center around the impact such inclusion will have on unit cohesion and effectiveness. Missing from the debate, however, are the perceptions of those who do the soldiering. What are their perceptions of cohesion? Do they, like political leaders and the general public, believe unit cohesion leads to military effectiveness? In other words, how much does the narrative at the elite level—that insists excluding minority groups is a military necessity—match the perceptions of those who serve? Drawing on an original survey of 151 current and former members of the US military, our results suggest that servicemembers’ perceptions mirror those in the general public: political ideology is correlated with beliefs that minority groups disrupt unit cohesion. We find that conservatives are more likely to believe that the inclusion of transgender soldiers will negatively impact cohesion and undermine unit effectiveness. Moreover, conservatives are more likely to endorse a conceptualization of cohesion that hinges on the social—“people like me” or “band of brothers”—dynamics of cohesion rather than more professional, task-oriented conceptions of cohesion. However, military experience affects these perceptions: respondents with combat experience, who held/hold a higher rank, and who are currently serving are more likely to endorse a task-based conception of cohesion that ties cohesion to professionalism and competence, rather than social identity.

The last two decades have seen technological innovations that have revolutionized the collection and transfer of information, permitting access to and dissemination of massive amounts of data with unprecedented speed and efficiency. These innovations have been incorporated into virtually every aspect of modern society, from personal communications, to commercial and business processes, to governmental function and military operations. The concept of network-centric warfare (NCW) grew out of these new capabilities and has been a prominent topic in strategic and operational discussions in the US military since the late 1990s.In recent years, the concepts behind NCW have been increasingly applied to emergency response, particularly as responders prepare for an increasingly complex threat spectrum in a post-9/11 world. As emergency responders adopt the technological innovations and organizational concepts that enable network-centric operations, attention should be paid to the lessons learned by the US armed forces in the application of the network-centric approach to war-fighting. Emergency operations centers (EOCs), incident command centers (ICCs), and field personnel will require extensive training and experimentation to sort out the impact of this new technology. They must develop protocols and procedures to leverage maximum advantage, while avoiding the undesirable and damaging effects of that technology improperly applied. Because most emergency response organizations lack the vast training resources of the US military, they must be innovative and adaptable in taking advantage of every opportunity to train their personnel in the assimilation of this new technology.

AbstractThis paper investigates the relationship between the US military spending and public debt in a panel of European countries in the period 1992–2013. Under the established evidence of the interdependence between US and European military spending, we exploited a dynamic panel estimation. Findings show that the debt of European countries is: (1) positively associated with US military spending; (2) negatively associated with average military burden of other European countries.

Questions regarding the economic consequences of US grand strategy have gained new salience. This article provides an empirical test of the relationship between US military expenditures and public debt and clarifies the real constraints the US faces issuing debt. Neither results from the statistical analysis nor the economic theory of sovereign debt support the retrenchment position regarding the impact of military spending on public debt (1973–2015). Tax cuts are the most significant determinant of debt not military spending, social benefits or interest payments. Evaluating new hypotheses about alternative mechanisms through which military spending may damage the economy remains a priority.

This chapter traces a series of climactic meetings of the National Security Council in December of 2006. By December, Vice President Dick Cheney thought it was “pretty clear that we've got to do something different than what we've been doing. December was then devoted to sort of nailing down what that was going to be.” The president and his advisors discussed fundamental issues regarding American goals and responsibilities in Iraq and increasingly concluded that only a surge option, as part of a change in military strategy and an effort at bottom-up political reconciliation in Iraq, could salvage the American mission there. That same month, the president visited the Joint Chiefs of Staff in their meeting room to hear and address their concerns about whether an intensified military effort in Iraq might overtax the US military and even “break the force.” In December, too, public discussion about the American future in Iraq was fueled by reports from the congressionally mandated Iraq Study Group, which advocated for a regional diplomatic strategy to help quell violence in Iraq, as well as from the American Enterprise Institute, which advocated increasing US forces in Iraq and pursuing a proper counterinsurgency strategy. The impact of these external reviews on the eventual surge decision remains hotly debated; the chapter helps place these efforts within the context of the internal administration policy process and Bush's decision making.

ABSTRACT Introduction In October 1985, 4 years after the initial descriptions of the acquired immunodeficiency syndrome (AIDS), the U.S. Department of Defense (DoD) began routine screening for human immunodeficiency virus (HIV) infection to prevent infected recruits from exposure to live virus vaccines, implemented routine active-duty force screening to ensure timely care and help protect the walking blood bank, and initiated the U.S. Military HIV Natural History Study (NHS) to develop epidemiologic, clinical, and basic science evidence to inform military HIV policy and establish a repository of data and specimens for future research. Here, we have reviewed accomplishments of the NHS over the past 30 years and sought to describe relevant trends among NHS subjects over this time, with emphasis on combination antiretroviral therapy (cART) use and non-AIDS comorbidities. Methods Subjects who were prospectively enrolled in the NHS from 1986 through 2015 were included in this analysis. Time periods were classified by decade of study conduct, 1986–1995, 1996–2005, and 2006–2015, which also correlate approximately with pre-, early-, and late-combination ART (cART) eras. Analyses included descriptive statistics and comparisons among decades. We also evaluated mean community log10 HIV viral load (CVL) and CD4 counts for each year. Results A total of 5,758 subjects were enrolled between 1986 and 2015, of whom 92% were male with a median age of 28 years, and 45% were African-American, 42% Caucasian, and 13% Hispanic/other. The proportion of African-Americans remained stable over the decades (45%, 47%, and 42%, respectively), while the proportion of Hispanic/other increased (10%, 13%, and 24%, respectively). The CD4 count at HIV diagnosis has remained high (median 496 cells/uL), while the occurrence of AIDS-defining conditions (excluding low CD4 count) has decreased by decade (36.7%, 5.4%, and 2.9%, respectively). Following the introduction of effective cART in 1996, CVL declined through 2000 as use increased and then plateaued until guidelines changed. After 2004, cART use again increased and CVL declined further until 2012-15 when the vast majority of subjects achieved viral suppression. Non-AIDS comorbidities have remained common, with approximately half of subjects experiencing one or more new diagnoses overall and nearly half of subjects diagnosed between 2006 and 2015, in spite of their relatively young age, shorter median follow-up, and wide use of cART. Conclusions The US Military HIV NHS has been critical to understanding the impact of HIV infection among active-duty service members and military beneficiaries, as well as producing insights that are broadly relevant. In addition, the rich repository of NHS data and specimens serves as a resource to investigators in the DoD, NIH, and academic community, markedly increasing scientific yield and identifying novel associations. Looking forward, the NHS remains relevant to understanding host factor correlates of virologic and immunologic control, biologic pathways of HIV pathogenesis, causes and consequences of residual inflammation in spite of effective cART, identifying predictors of and potential approaches to mitigation of excess non-AIDS comorbidities, and helping to understand the latent reservoir.

AbstractThis paper explores the impact of the 1991 Mt Pinatubo eruption on the US-Republic of the Philippines military relations through the lens of disaster diplomacy. Disaster diplomacy focuses on how and why disaster-related activities (e.g. mitigation, prevention and response) do and do not yield diplomatic gains, looking mainly at disaster-related activities affecting diplomacy rather than the reverse. Disaster diplomacy 'pathways', identified in previous studies, help to explain how the Filipino and US governments approached the negotiations for renewing the lease of the US military facilities in the Philippines in the context of two bases being damaged by a volcanic eruption. The paper further addresses six underpinning questions of disaster diplomacy for this case study. These questions assist in answering this paper's central research question: how much did the 1991 eruption of Mt Pinatubo influence US-Philippines military cooperation due to the concurrent diplomatic talks between the two governments regarding the lease renewal for the US bases in the Philippines? The answer is that disaster-related activities due to the Mt Pinatubo eruption had a short-term impact on US-Philippines diplomacy. This impact was seen in the context of significant connections already existing, through the long-standing US-Philippines military links. Over the long-term, non-disaster factors had a more significant impact on US-Philippines military diplomacy than Mt Pinatubo, adding to the list of case studies for which disaster diplomacy's impact was limited.
