ABSTRACT

This article analyses the Zimbabwe People’s Revolutionary Army operations in Mashonaland West province with particular reference to Makonde District during the country’s war of liberation. Despite the growing literature on ZAPU and ZPRA in Zimbabwe’s war of liberation there is little that has been written concerning the operations of ZPRA guerrillas in Mashonaland provinces. Guided by evidence drawn from secondary and primary sources the article further asserts that ZPRA adopted a four pronged strategy in Makonde District. This strategy in part was hinged on the politicization of the population on the one hand and annihilation of the enemy forces, attrition and manoeuvre warfare on the other. Again, the article argues that ZPRA guerrillas attempted to capture Salisbury (Harare) in order to conquer the Rhodesian Security Forces’ centre of gravity. It was hoped that the capture of the capital city would Makoni District was of strategic significance to the conduct of ZPRA operations and arguably hastened Ian Smith’s decision to attend the Lancaster House Conference negotiations that led to the independence of Zimbabwe in 1980.  相似文献

The Soviet Union was able to develop a large military-industrial complex and become the world's second superpower despite deficiencies in its centrally planned economy because defence was given high priority status and special planning, rationing and administrative mechanisms were used to attain national security objectives. However, in the period 1976-85 the effectiveness of priority protection diminished and defence institutions experienced more of the problems typical of the shortage economic system. The heavy defence burden also created growing difficulties for the civilian economy. The attempts by the Gorbachev government to reform the defence sector and improve defence-economic relationships during perestroika (1985-91) uniformly failed. For most of the transition period, the Russian military-industrial complex has been adversely affected by its low priority status, cuts in defence spending, instability of the hybrid politico-economic system, and negative growth of the economy. The armed forces and defence industry have been reduced in size and their outputs of military services and equipment have fallen to low levels. Nevertheless, the Russian armed forces still have over one million troops, significant stocks of sophisticated conventional weapons, and a large nuclear arsenal. The government of President Putin has raised the priority of the defence sector, increased real defence spending, and adopted ambitious plans to revive Russian military power. It is likely, though, that tight resource constraints will hamper efforts to reform the armed forces and to upgrade weapons. By 2010 Russia will be an important, but not dominant, military power in Eurasia.  相似文献

European defence policy has been dominated by politics. This paper shows how economic principles can be used to derive guidelines for the formulation of European defence policy. The inefficiencies of the EU's existing defence arrangements are identified. It is shown that there is scope for efficiency improvements in the EU's Armed Forces and its defence industries.  相似文献

When it was concluded more than a quarter century ago, the Intermediate-Range Nuclear Forces (INF) Treaty between the United States and the Soviet Union was hailed as a disarmament watershed, eliminating entire classes of nuclear missiles from the arsenals of the arms-racing Cold War superpowers. Over the intervening decades, there have been repeated calls to convert this legacy treaty into a new international norm against nuclear and missile proliferation by broadening it into a global prohibition on ground-launched ballistic and cruise missiles with ranges between 500 and 5,500 kilometers. Indeed, variations on this proposal have been knocking around for so long and with so little success that the entire concept has come to be dismissed by many knowledgeable insiders as something of a farce. Looking beyond its inauspicious pedigree, however, this viewpoint suggests that the time is opportune for Washington to give the idea a fresh look. Drawing on a detailed review of the history of “Global INF” and an analysis of the contemporary context, the author recommends that the Obama administration consider a simple declaratory approach that promises modest initial benefits, avoids previous and foreseeable pitfalls, and plausibly lays a solid foundation for achieving significant long-term progress.  相似文献

路径规划识别是一种以位置信息为输入的在线识别。为了使CGF能在仿真中识别对手的路径和终点目标,在分析路径规划层次的基础上引入了抽象隐马尔可夫模型的识别框架。针对标准模型在对手更改终点目标和自上而下规划时无法识别的问题,提出了一种顶层策略可变的抽象隐马尔可夫模型。为模型的顶层策略增加初始分布和策略终止变量,更改了策略终止变量间的依赖关系,使下层策略能被强制终止。给出了改进后DBN结构,并通过推导条件概率更新和RB变量抽样流程实现了模型的近似推理。仿真实验表明,改进模型能准确识别给定环境下的各类典型航迹,不仅在终点目标不变时能较好地维持标准模型的识别准确率,在提供足够的观测数据后还能很好地解决变目标识别问题。  相似文献

对战场态势的不完全观测是潜艇作战的重要特点,充分利用不完全观测信息,提高潜艇对抗决策的合理性是设计潜艇CGF的核心问题。针对潜艇作战特点,提出了潜艇自防御行为模型框架,并利用多Agent不确定场景建模技术,建立了基于POMDP的规避反潜航空兵行为模型,最后进行了仿真验证。结果表明,该模型具有较强的可行性。  相似文献
