ABSTRACTThis article discusses the Rhodesian Front regime propaganda warfare strategy during Zimbabwe’s war of liberation. It uses the case of the Chilonga area of Chiredzi located in the south-east of Zimbabwe to demonstrate that propaganda warfare was introduced as a measure to counter guerrilla infiltration and civilian cooperation with them. Drawing on ideas of military anthropology vis-à-vis the importance of cultural awareness in counterinsurgency, the paper argues that the efforts of the Rhodesian Front regime to use propaganda were fruitless. This is because they mostly ignored the culture of the Shangani, local people. Despite that, there were other reasons for the failure of the Rhodesian Front’s propaganda strategy, including the lack of conformity between politics and military action. 相似文献

Croatia's successful bid for independence was one of the defining moments of the immediate post-Cold War period. Nevertheless, the means that Croatia used to obtain independence remains relatively unexamined by academics. This article focuses on the early period of Croatia's bid for secession, and specifically the role that Yugoslavia's policy of Total National Defence played in facilitating its independence. Unlike in Slovenia, where the legacies of Total National Defence facilitated Slovenia's bid for secession, in Croatia the decision of its political leaders meant that the country largely neglected its positive legacies, resulting in a protracted four-year struggle. 相似文献

There were several high-profile violent incidents in 2011 in Kazakhstan, including several bombings, shootings that targeted police, and a protest turned clash that resulted in a number of deaths. Some of the perpetrators reportedly had links with radical religious groups. An overlooked aspect of the violence is how it is reported in Kazakhstan. There are active, competent media in Kazakhstan, which are largely unknown in the West. An examination of these incidents using the media in Kazakhstan can provide a unique insight into what took place. While Western sources quickly blamed radical religious groups with international connections, media in Kazakhstan have found that there are other reasons for the violence. 相似文献

Since the peace agreements of 2002–2003 which ended the second war in the Democratic Republic of Congo, reconstruction of the army has been an inherently political process, in common with other attempts to carry out security sector reform (SSR). This article briefly sketches out the Congolese army's history, then attempts to fill a gap in the literature on Congolese SSR by detailing what can be found of the actual structure and shape of the present army. The efforts that have been made to reform the army are then examined, followed by a conclusion which examines the major issues and possible ways forward. 相似文献

On 4 January 1961 in Baixa do Cassange, in the north of Angola, the blacks who worked in the cotton fields began a strike. The army with air support was called to quell the rebellion, and the article emphasizes the importance of air support tethered to the ground forces, particularly in a remote and vast area of operations in the tropical rainy season. In this case, the support originally came in the form a squadron of Lockheed PV-2 Harpoons from Luanda, some 300 kilometers away. These open-ocean reconnaissance aircraft and their crews were ill-suited for the task. When this became apparent, four small Auster D5/160s were relocated from Negage to Malange, among the ground forces. The Austers flew reconnaissance missions over the troubled zones, dropped provisions and messages to the advancing ground forces, and served as a backup communications link. When the strike ceased after three weeks, the Austers assumed a humanitarian role in support of the starving population. The conclusion is that air support to ground forces is indispensable, must be properly tailored to the job, and must operate as an integral part of the ground forces. 相似文献

不确定条件下的不完备信息分析是多属性决策中的主要内容之一,Yang提出的证据推理方法可以较好地处理这类信息。研究了证据推理方法中不完备信息的影响因素,包括规则中的不完备信息,规则的权重以及规则的一致性,并以此为基础分析了评估结果中不完备信息的取值范围,得出了初步结论:评估结果中不完备信息的信度必然小于作为输入的规则中不完备信息中的较大者,但不一定大于其中的较小者。进一步分析了规则一致性的逻辑意义和几何意义,指出规则的一致性实际描述了规则之间的冲突程度。 相似文献

ABSTRACTWhen on the wrong end of an asymmetry in the projection of hard power, weaker sides countenance the grim arithmetic of avoiding direct and massed confrontations. Invariably, insurgents have over the ages tended to employ indirect tactical methods to render their stronger opponents ineffective. Ultimately – interest asymmetry, regime type, asymmetries of strategy, and external intervention – combine in a complex interplay and pattern, to militate against a strong side. In Sudan, these factors interacted throughout the civil wars to produce regional autonomy and finally an independent South Sudan in 2011. Similar strategic logic had confronted many large African states battling insurgencies in Ethiopia, Angola, Nigeria, Zaire, and apartheid-era South Africa. Oftentimes, weakening public resolve has caused these governments to accommodate, capitulate or withdraw even if they try not to blink. Notwithstanding the regime type, it can be concluded that the majority of strong actors are prone to fail in a protracted, asymmetric conflict. Hence, the notion of linking victory in counterinsurgency to the degree of openness (democratic polyarchies); or closeness (totalitarianism) – is still valid but highly contestable in the case of Africa’s large dysfunctional states. 相似文献

ABSTRACTThis paper concerns the lesser known British counterinsurgency (COIN) operations in Northeast frontier of India during the First World War. Officially known as the ‘Kuki Operations’, it was considered as part of the Great War. Carried out in isolation from press and public, and shelved in colonial archives, the event remained invisible until today. Yet, it registers a critical case of colonial COIN doctrine where the ‘moral effect’ doctrine was employed without being questioned. It unleashed enormous amount of organized violence, ranging from shoot at sight to indiscriminate burning of villages, wholesale destruction of property and livestock, prevention of cultivation and rebuilding of villages, forced mass displacement in jungles or in ‘concentration camps’, and collective punishment (communal penal labour and payment of compensation) after the war. This paper argues that the theory of ‘minimum force’ and the practicability of the ‘moral effect’ doctrine as applied by the Empire, sit oddly with each other at the frontier, where violence was seen both as a natural and moral orders. Violence as an ‘imperatively necessary’ method to bring order in a disorderly frontier, in the opinion of colonial state, informs and registers Northeast India as geography of violence. 相似文献

在领航-跟随编队模式下,设计了一种基于追缉策略的无人机编队会合方法。首先,基于微分几何曲线论和弗雷涅-塞雷标架建立了无人机非解耦三维运动模型,其中将曲率和挠率作为控制量;结合该模型给出了无人机三维编队会合问题的数学描述,它将导弹制导问题中的终端落角约束映射为编队会合问题中僚机的航迹倾角约束,同时引入额外的航迹方位角约束;然后使用特殊正交群的元素来度量长僚机方向偏差,并通过局部坐标映射将其映射为对应李代数空间中的旋量;接着,基于该旋量设计了编队会合几何导引律,并给出相应的曲率和挠率控制指令;最后,分别在长机稳定平飞和转弯机动条件下进行了多机编队会合数字仿真实验,仿真结果显示僚机能够有效地跟踪长机航向并收敛至指定位形,说明了方法的有效性。 相似文献
