Target Analysis of Shining Path Insurgents in Peru: An Example of US Army Psychological Operations

This article analyzes the assumptions of US and Peruvian military personnel regarding insurgent susceptibilities to psychological operations in 1988. The discussion is based on both archival material and the experiences of the author, who was a member of the joint US-Peruvian team. The paper provides insight into the workings of US Army psychological operations as they were conducted in the 1980s and outlines both the strengths and weaknesses of the approach taken.     

试论联合国维和行动的法律性质

联合国维持和平行动的法律性质在国际法学界一直存在争议。在维和行动与其他国际军事或准军事行动的辨析中我们可以看到维和行动自身所独具的法律特征。维和行动的法律依据尽管未有定论,但依据其实践与发展的现实状况,我们可以将它的法律性质概括为:联合国属准军事行动性质,国际法约定的默示授权性质,维护国家间独立平等的工具性质等。     

基于支持向量机的制造系统静态复杂性综合模型研究

制造系统复杂性对优化制造系统结构设计、提高制造系统的生产效率具有非常重要的意义.然而目前对静态复杂性及动态复杂性影响因素复杂性及其测度的研究较多,对于如何将这些分因素复杂性进行综合得出综合复杂性的研究较少,这直接影响了复杂性研究结果的准确性。鉴于此,引入擅长处理小样本数据的支持向量机对制造系统静态复杂性进行综合,用遗传算法对其参数进行寻优,对模型的有效性进行了验证,结果说明方法的实用性与科学性较强.

Military Innovation Under Authoritarian Government – the Case of Russian Special Operations Forces

Russian Special Forces saw significant changes to both organization and doctrine in the years after 2008. The special forces of the General Staff’s Main Intelligence Directorate were reduced in number, the organization’s institutional autonomy and rationale were changed, and an entirely new Special Operations Command was established in March 2013. This article seeks to assess the nature, scope and purpose of these changes, and to explain them by drawing on scholarship on military innovation. In particular, the article looks at military innovation in the context of a non-democratic political regime.     

Countering Insurgents through Distributed Operations: Insights from Malaya 1948–1960

This article examines the emerging US Marine Corps concept of ‘Distributed Operations’ (DO) and its applicability to counter-insurgency. DO involves dispersing the force and empowering decentralised units so as to create a network of mobile, agile and adaptable cells, each operating with a significant degree of autonomy yet in line with the commander's overall intent. This concept's applicability to irregular campaigns is assessed with reference to the Malayan Emergency, in which the British and Commonwealth forces employed dispersed and decentralised small-unit formations to great effect. The article teases out the conditions that allowed DO to succeed in Malaya, and comments on the requirements and implications for the use of DO today in the prosecution of the ‘Long War’.     

French Exception or Western Variation? A Historical Look at the French Irregular Way of War

ABSTRACT

This article aims at challenging the notion of a French exception in the realm of irregular warfare, suggesting that it rather amounts to a western variation. Born out of a transatlantic community under British influence, the French irregular experience carried on through the early Cold War challenges, strengthening France’s ties with its Western allies. France’s subsequent involvement in post-colonial counter-insurgencies did contribute to generating some specific strategic features, although never totally disconnected from international circulation. Finally, the post-Cold War order significantly drove French irregular warfare back into its Western fold through the adoption of US- and NATO-sponsored concepts and doctrines, thus enhancing interoperability and some degree of standardisation.     

Analysing coalition warfare from an intra-alliance politics perspective: The Normandy Campaign 1944

This article sets forth a framework for analysis designed to enhance our understanding of the political management of coalition warfare. The framework, based upon literature appertaining to ‘intra-alliance politics’ and International Relations (IR) theories, is applied to the case study of the Normandy Campaign of 1944. Utilising this framework we are able to consider many of the thorny issues of coalition politics and determine how these can be managed successfully to maintain Allied cohesion. Throughout the analysis the merits of the ‘realist’ and ‘pluralist’ views on maintaining Allied cohesion are appraised. The article concludes that, while both afford convincing explanations for overcoming tensions within the coalition, the pluralist approach proves superior in accounting for Allied unity. Overall, the article demonstrates that the intra-alliance politics framework is a useful device for understanding the political dynamics of the Normandy Campaign in 1944 and that it is also potentially applicable to other instances of coalition warfare; past, present, and future.     

试论联合国维和行动的理念演变

联合国维持和平行动的指导理念随着国际局势的发展而不断变化,其中既有自身的发展与完善,也折射时代的演进和各种政治力量的对比。联合国维和行动产生初期遵循绝对中立理念,冷战后准军事介入阶段带有明显的隐性强权理念,反恐时代则对维和理念演变产生了新的影响。     

Building A New Luftwaffe: The United States Air Force and Bundeswehr Planning for Rearmament, 1950–60

Rearming Germany was a long and complicated process. It was especially difficult to create a new German air force. The army generals who dominated the Bundeswehr cadre did not even want an air force but rather a small arm air corps. Moreover, Adenauer's defense staff failed to adequately budget or plan for a new air force. As rearmament began, US Air Force leaders, working closely with the small Luftwaffe staff in West Germany's shadow Defense Ministry, basically took charge of the process to ensure that the Germans built a new Luftwaffe on the American model – a large, multipurpose force organized as an independent service and fully integrated into NATO. The first Bundesluftwaffe commanders allied themselves to the Americans, often in opposition to their army comrades, to overcome the political problems caused by Adenauer's poor defense planning and create a modern air force on American lines.     

The open shop scheduling problem with a given sequence of jobs on one machine

The paper considers the open shop scheduling problem to minimize the make-span, provided that one of the machines has to process the jobs according to a given sequence. We show that in the preemptive case the problem is polynomially solvable for an arbitrary number of machines. If preemption is not allowed, the problem is NP-hard in the strong sense if the number of machines is variable, and is NP-hard in the ordinary sense in the case of two machines. For the latter case we give a heuristic algorithm that runs in linear time and produces a schedule with the makespan that is at most 5/4 times the optimal value. We also show that the two-machine problem in the nonpreemptive case is solvable in pseudopolynomial time by a dynamic programming algorithm, and that the algorithm can be converted into a fully polynomial approximation scheme. © 1998 John Wiley & Sons, Inc.

Cyber War Will Not Take Place

A large collection of captured documents from the very highest levels of the Iraqi government offers a chance to gain insight into why Saddam Hussein was unwilling and unable to alter his strategy on the eve of the 2003 war that toppled his regime. This paper explores some of the perceptions and misperceptions that Saddam Hussein took away from the 1991 Gulf War and shows how they affected his decisionmaking on the eve of the war in 2003. It concludes with some thoughts on the policy implications of these findings.
