Despite all the talk of ‘hearts and minds’ being the key to counterinsurgency, local public opinion is rarely studied and when it is, it often yields surprising conclusions. Through analyzing polling data from Vietnam, Iraq and Afghanistan, this article shows that public opinion is less malleable, more of an effect rather than a cause of tactical success, and a poor predictor of strategic victory. As a result, modern counterinsurgency doctrine’s focus on winning popular support may need to be rethought. 相似文献

This article proposes two dual‐ascent algorithms and uses each in combination with a primal drop heuristic embedded within a branch and bound framework to solve the uncapacitated production assembly distribution system (i.e., supply chain) design problem, which is formulated as a mixed integer program. Computational results indicate that one approach, which combines primal drop and dual‐ascent heuristics, can solve instances within reasonable time and prescribes solutions with gaps between the primal and dual solution values that are less than 0.15%, an efficacy suiting it for actual large‐scale applications. © 2012 Wiley Periodicals, Inc.

Following the emergence of a communist regime in South Yemen and the multiplication of subversive movements in the United Kingdom's Gulf protectorates, British policymakers genuinely feared the spread of communism throughout southern Arabia. Defeating the People's Front for the Liberation for the Occupied Arabian Gulf (PFLOAG) insurgency in Oman's Dhofar province was considered central to preventing such an outcome. In their pursuit of victory, British officers overthrew the sultan of Oman, escalated the war by conducting attacks in South Yemen, and, ultimately, appealed to Islam as a means of rallying support against communism. However, lessons learned in previous counterinsurgencies (Malaya, Kenya, and Borneo) proved of only limited value in Oman's physical and cultural environment. Unfortunately, none of these measures worked as anticipated. Only Iran's direct military intervention and the dramatic growth of Oman's financial resources after the 1973 oil crisis provided the resources to conduct large-scale offensive operations. Even so, victory was only achieved in 1975 because the rebellion's leaders unwisely attempted to oppose the Anglo–Omani offensives conventionally. 相似文献

AbstractThe 1919-1921 Anglo-Irish War represents one of the earliest instances of a successful insurgent movement in the twentieth century. By combining a fluid organizational structure with effective hit-and-run tactics and accurate intelligence, the Irish Republican Army was able to defeat militarily the security forces of Great Britain. Combined with a successful propaganda campaign, these tactics allowed the IRA to drive the British to the negotiating table, where its representatives secured greater autonomy than Ireland had known in centuries. The outcome of the Anglo-Irish War demonstrates the success which a well-organized guerrilla campaign can achieve, and the tactics used by the IRA must therefore be understood by any serious student of small warfare. 相似文献

针对坦克炮控系统未知齿隙及摩擦,设计了基于性能的新型控制器.提出了基于侵入和不变流型(I&I)的未知参数估计率的构造方法,使调节函数的选取及I&I估计率的设计变得直接简便.由于未知齿隙及摩擦被充分的描述成有界扰动与非线性动态项的组合,从而避免了将其简单的考虑成“总扰动”所造成的被控系统性能的损失.该控制器可有效抑制负载扰动及参数变化所带来的影响.同时通过快速准确的估计系统参数实现了对指令信号快速精确的跟踪. 相似文献
