A nation's structure and culture of civil-military relations are important and largely overlooked factors in explaining the performance of armed forces involved in complex expeditionary operations. The US model of ‘Huntingtonian’, divided civil-military structures and poor interagency cooperation, makes the US military less suited for complex expeditionary operations. British civil-military relations involve a Defence Ministry that conscientiously integrates military and civilian personnel, as well as extensive interagency cooperation and coordination. This ‘Janowitzean’, integrated form of civil-military relations makes the British military more likely to provide for the planning and implementation of comprehensive campaigns that employ and coordinate all instruments of power available to the state, as well as troops in the field displaying the flexibility and cultural and political understanding that are necessary in complex expeditionary operations. 相似文献

Personal cognitive processes inform how individuals understand their environment. Cultural variation, fundamental attribution error, causal attribution, and durability bias create obstacles to Western understanding of irregular war and have created a significant institutional bias in how the US military perceives its enemies- a perception only somewhat softened after a decade of irregular war. United Special Operations Command (USSOCOM) is in a better position to overcome these problems through persistent engagement. In the event of major conflict, environmentally sensitized military planners will be better able to achieve military and policy objectives. 相似文献

Did participants in small wars in the period 1775–1831 learn from previous or contemporary examples? While this is difficult to prove for participants who left no written records, there is considerable evidence in existing publications by practitioners that they did indeed draw out lessons from recent insurgencies, either from their own experience or from events elsewhere which they studied from afar, especially the Spanish Guerrilla, which had already become legendary. Most authors showed an interest in how to stage insurgencies rather than in how to quell them. Even then, transfer did not come in a package of tactics-cum-values, but in each case in different configurations. 相似文献

Each age has its own wars and its own forms of warfare. In today’s evolving world risk society warfare has entered a new development stage. The states of the “global North” adapt their forms of intervention. They increasingly practice postmodern warfare characterized especially by the role of influencing the information space, networked approaches, the incorporation of indirect and covert actions, and the special quality of new technologies. This practice furthers an increasing grey zone between limiting and de-bounding of warfare. The phenomenon of postmodern warfare raises some tough questions and offers a rich research agenda. 相似文献

This article examines the evolution of US irregular warfare (IW) doctrine and practice from 2001 onwards. It argues that, after 9/11, top-tier civilian policymakers in the US Department of Defense (DoD) and across the US government developed a heightened awareness of asymmetric threats and non-conventional forms of warfare, especially those shaped by contemporary globalisation. The result was a gradual turn towards irregular warfare, led by Rumsfeld and the DoD, designed to ensure ‘full spectrum dominance’ across all modes of conflict. This pre-dated the insurgency in Iraq and the promotion of counterinsurgency in the US Army by General David Petraeus and others. Policymakers' reluctance to acknowledge the insurgency in Iraq was not down to a failure to understand the concept of IW, but because they had viewed Iraq in conventional terms for so many years and were reluctant to admit their mistake. 相似文献

根据灭雷具上高分辨率图像声呐的工作原理和探测过程,从为部队官兵提供模拟训练平台的角度出发,利用计算机的图形、图像处理和虚拟现实技术,提出一种数学模型和物理模型相结合的图像声呐可视化建模思路。通过仿真,证明此种方法既便于计算机实现,又符合灭雷具图像声呐的真实探测和显示过程。同时,为了整个仿真系统的需要,简单地给出了系统中三维海底地形和水雷目标的数据模型和构造方法。 相似文献
