It has long been held that the Federation of Malaya’s counter-insurgency campaign during the First Malayan Emergency (1948–60) was determined by the use of intelligence. Special Branch — the Federation’s primary intelligence agency — dominates the prevailing paradigm of how the insurgent threat was tackled. Conversely, the role of the Royal Air Force (RAF) within this paradigm is very limited. Most observers simply dismiss the role of photoreconnaissance or airstrikes as being largely inconsequential to the counter-insurgency effort. This is perhaps understandable: the Emergency was after all a ‘policing action’ and the insurgents were largely hidden under Malaya’s jungle canopy and amongst the Chinese community. However, further scrutiny reveals that the RAF made a much more significant contribution to the intelligence element of the counter-insurgency campaign than previously realised. First, the RAF decided to locate their Advanced Headquarters with the Army’s General Headquarters. This led to the creation of the Land/Air Operations Room, through which intelligence, tasking and resources were coordinated. Moreover, the RAF put its intelligence teams into the field to provide a practical link between local units and theatre-level assets. Second, with the support of the Army, the RAF established at the beginning of the Emergency the Joint Air Photographic Intelligence Board (Far East). This coordinated all photographic intelligence requirements throughout the Emergency, which was then delivered via the Joint Air Photographic Centre (Far East). Hence, via Joint Operations Centre and JAPIB (FE), the RAF provided both the practical means for effective joint intelligence operations at theatre level throughout the Emergency.  相似文献

针对BP神经网络对初始值敏感、容易陷入局部寻优且收敛速度较慢,提出用粒子群对神经网络的参数进行优化,同时设计了衰减的指数函数对惯性权重进行动态调整以提高算法性能.并应用该算法对导弹飞控系统的逆误差进行补偿,仿真结果表明,该方法对逆误差进行了有效的补偿,避免了局部寻优并提高了学习效率.  相似文献

在可视导航卫星数少于四颗、无法进行传统导航解算的恶劣环境下,导航接收机可利用外部高程气压计提供的高程或者内部守时模块的钟差等信息进行应急辅助定位。在该应急辅助定位工作模式的误差分析中,传统导航定位误差传递模型无法适用。针对此问题,本文在研究三星结合高程、三星结合钟差、双星结合高程钟差等几种应急辅助定位原理的基础上,给出了新的应急辅助定位误差传递的分析模型,利用仿真算例验证了该模型的正确性。通过对定位精度的分析,说明根据卫星分布特点可以按照本文方法量化得到伪距测量与辅助信息的精度的最优数量级关系,可以用最小代价实现定位精度的提升。该结论可指导接收机外部辅助器件的选择。  相似文献

The purpose of the current paper is to examine the adoption and adaptation process of mission command (Auftragstaktik) in the US Army. This concept, developed by the Prussians, denotes a decentralized command approach wherein superiors dictate their intent and allow subordinates to formulate their operational plans independently and change it according to the emerging situation. The paper examines the US command approach prior to the adoption of mission command. It argues that it was heavily influenced by corporate management practices which inherently contradict mission command approach. It continues and investigates how the US Army endeavored to emulate the approach in its doctrine and in major operations.

While it has officially incorporated mission command into its doctrine, it has been less successful in utilizing it in operational situations. This state of affairs has to do with the cultural legacy of the managerial approach to command that still persist. Despite the partial success, the US Army has recently reaffirmed its commitment to this approach.  相似文献

This article uses a novel database of 1,625 posthumously published biographies of members of two Islamist militant organizations (Lashkar-e-Taiba (LeT) and Hizb-ul-Mujahideen (HM)), all of whom were killed in the course of carrying out militant attacks. In general, each biography provides data on the militant’s birthplace, education, recruitment, and training. The number of observations in this database is a full order of magnitude larger than those of previous databases assembled from militant biographies. While the sample of militants in this database is the product of multiple selection effects, analysis of the database undermines many common myths about Pakistani militants and casts doubt on current policy approaches to mitigating Islamist militancy in Pakistan.  相似文献

Over seven years after the 11 September 2001 attacks on the United States, Afghanistan is again at the forefront of the headlines, faced with a brutal insurgency and a resurgent Taliban. Many scholars and policymakers attribute the instability in Afghanistan to a terrorist sanctuary in the neighboring Federally Administered Tribal Areas (FATA). Pakistan has attempted to eliminate this sanctuary through negotiation and armed force. This paper argues that Pakistani strategy has failed to achieve its desired results because of local tribal norms, the weak nature of previous agreements, military units ill-equipped for a counterinsurgency and counterterrorism role, as well as ideological fissures in the Pakistani establishment. Afterward, the paper argues that the United States and Coalition forces should pursue their strategy remaining cognizant of local tribal norms, step up training efforts for Pakistani forces, promote development of the tribal areas, and cultivate options for eliminating the FATA sanctuary through covert means.  相似文献

基于元模型的体系结构设计思想和基于可执行模型的评估方法是体系结构领域研究的两个热点,但当前的研究没有将两者结合起来。文章基于DoDAF2.0提出的元模型数据(Meta-Model Data,DM2),将元模型的思想和基于可执行模型的评估方法相结合,分析了基于DM2的逻辑数据与可执行模型各构建要素的对应关系,构建了基于DM2的逻辑数据模型直接转可执行模型的过程框架,重点研究了如何直接从体系结构底层数据转可执行模型的方法,从而为进行基于元模型的体系结构可执行评估提供模型基础,也为进一步实现体系结构自动化验证评估提供技术支持。实例验证了文章提出的方法。  相似文献
