British and German initiatives for defence cooperation: the Joint Expeditionary Force and the Framework Nations Concept

At NATO’s 2014 Wales Summit, the UK and Germany unveiled two new initiatives for European defence cooperation, known, respectively, as the Joint Expeditionary Force (JEF) and the Framework Nations Concept (FNC). Both were the result of economic pressures and the need to exercise intra-alliance leadership, but they represented very different approaches to cooperation. The JEF was to be a UK-led contingency force for short-notice operations, selectively incorporating forces from allies and partners. The FNC sought to coordinate capability development between groups of allies, centred on larger framework nations, to develop coherent capability-clusters available to meet NATO’s force requirements. The common denominator and novelty of the initiatives was the building of forces and capabilities multinationally by having major states act as framework nations for groups of smaller allies. The UK and Germany have ownership and continue to provide leadership to these initiatives. This is one key reason why they continue to evolve to accommodate changing circumstances and are likely to endure.     

Sharing security in an era of international cooperation: unmanned aerial vehicles and the United States’ Air Force

The United States’ Air Force (USAF) has developed and used unmanned aerial vehicle (UAV) technology to monitor and assassinate dangerous terrorists in Afghanistan, Iraq, Libya, Pakistan, Somalia, Syria, and Yemen. Currently, there are few countries that possess armed UAV and since the US created much of this technology, the USAF is usually part of the training that automatically accompanies the purchase of its UAVs. The research question this article attempts to answer is, “What is the extent of the United States’ Air Force assistance in the training and proliferation of UAV technology to foreign militaries?”     

India–Africa defence cooperation against the backdrop of the ‘Make in India’ initiative

Although India is a major importer of defence equipment, it has also been manufacturing defence equipment for some of its needs. The Government of India’s ambitious ‘Make in India’ initiative for the defence sector aims to achieve self reliance in defence equipment production. This essay explores the opportunities for bilateral arms trade between India and Africa, as a new facet of India-Africa defence cooperation. It covers India’s arms export policy, policy reforms in India’s defence sector, and the opportunities for Indian and African defence markets.

论打击防范“三股势力”犯罪的立法完善

国际恐怖主义和包括“东突”势力在内的民族分裂主义、宗教极端势力和暴力恐怖势力等“三股势力”是危害我国社会和谐、国家安全的主要因素之一。坚持依法打击和防范是治本之策,但现行相关法律还存在着许多空白和不足之处,亟待完善。为此,建议国家积极与周边国家签订或完善打击防范“三股势力”的双边或多边合作协定,充实协作机构;进一步完善刑法、刑事诉讼法和刑侦、安全、边检、金融等法律在打击和防范“三股势力”犯罪方面的具体规定;适时出台《反“三股势力”法》。     

认知无线电专题讲座(四) 第7讲 协同频谱检测技术

认知无线电能够智能地感知频谱并在授权用户没有使用的时候伺机(opportunistic)利用其频段,从而提高频谱的利用率。频谱检测是认知无线电系统需要首先解决的问题。协同检测可以更有效地利用整个网络的资源,获得高的分集增益,使网络性能更稳定。文中简述了协同检测的基本原理,并对协同频谱检测技术进行了讨论。仿真结果表明协同可以提高检测概率、提供捷变增益(agility gain),对频谱利用率的提高有很大的贡献。     

Command Coordination and Tactical Effectiveness in Counter-insurgency Operations: Lessons from the South Korean Campaign

This article analyzes the causes of combat effectiveness of the South Korean security forces through the course of its various counter-insurgency (COIN) operations from 1948 to 1953. We argue that improvements in two interrelated aspects ultimately resulted in higher operational and tactical level performance: unified operational command structure and the subsequent improvements in tactical efficiency under the guidance of the US advisory mission. Through an in-depth case study on how a nascent army improved its capacity in combating homegrown insurgencies, we demonstrate how the actual conduct of operations itself remains just as significant in the assessment of overall COIN outcomes.     

Militarisation of cooperation against mass migration – the Central European Defence Cooperation (CEDC)

As a result of the migration crisis of 2015–2016, the management of mass migration and border control became militarised in Central Europe, and this process has also reshaped the dynamics of multinational defence cooperation in the region. Accordingly, while the so-called Central European Defence Cooperation (CEDC) was created by Austria, Croatia, the Czech Republic, Hungary, Slovakia and Slovenia in 2010 to support NATO and EU capability development projects via defence cooperation, after the migration crisis it became the major Central European forum for military cooperation against irregular mass migration. Although many defence officials in the region are not necessarily enthusiastic about this development, the Central European political environment and also practical defence considerations pushed the defence ministries of CEDC countries towards deeper cooperation on border control, as well as better coordination with ministries of interior affairs on the national and the regional levels.     

Trilateral defence cooperation in the North: an assessment of interoperability between Norway,Sweden and Finland

Norway, Sweden and Finland have proclaimed a willingness to cooperate militarily in a future crisis or conflict despite their diverging alliance affiliation. This article assesses their ability to do so through various elements affecting their interoperability, with Arctic Challenge, a multinational military exercise, as an empirical basis. The analysis finds that the NATO/non-NATO-divide has a negative impact on the trilateral defence cooperation, especially on exchange of information and aspects related to command and control. At the same time, Finland and Sweden have become largely NATO-standardized through their active partnership with the Alliance. This has affected interoperability aspects, such as communication, culture, and the compatibility of technical solutions, in a positive manner. Through agreements with the Alliance, as well as domestic legal changes, the two NATO-partners have facilitated receiving military assistance from Norway and other NATO-members during a crisis. Other agreements between the Nordic countries, however, have been limited to peacetime.
