EU armed forces and social media: convergence or divergence?

This article explores how armed forces in EU member states work with and view social media in national and international settings, and what the patterns of convergence/divergence are on these issues. To that end, a questionnaire targeted at EU armed forces was constructed. An index of qualitative variation was calculated to explore the relative convergence among respondents (n = 25) on issues of risks and opportunities with using social media nationally and internationally. Consistent with previous research on European armed forces, we found higher levels of divergence than convergence. Contrary to our expectations that similar challenges, joint international standards, and membership in international organizations would foster convergence with regard to social media use in areas of deployment, we found that convergence appeared foremost pertaining to the domestic level. Policy divergence was strongest in areas of deployment.     

Explaining the security paradigm shift: strategic culture,epistemic communities,and Israel’s changing national security policy

The paper’s main argument is that Israel’s security policy, which traditionally focused on defending its territorial integrity against regular Arab armed forces, was, by the 2010s, transformed into one that focuses on facing a variety of state- and non-state-based threats. Neo-realist explanations could neither account for the contested nature of the security debate during this period, nor the inconsistent evolution of the policy. The present study aims to solve this conundrum by introducing an alternative approach known as 4th generation strategic culture research. The paper is comprised of four parts. First, the origins and evolution of strategic culture are reviewed, with emphasis placed on the commonly accepted weaknesses that, to date, have prevented it from being used as a testable theoretical concept, and subsequently as an explanatory factor for security policy changes. The second part presents the “modernist constructivism” approach that bridges the gap between traditional constructivism and hypothesis-driven research design. Next, the paper introduces the emerging fourth generation in strategic culture literature, followed by a conceptual framework designed to resolve the inherent weaknesses of the more traditional approaches. Finally, this conceptual framework is applied to analyse the transformation of Israel’s security policy between 1982 and 2014.     

Human conflict and universal ethics (part 2)

This second part of the review article begins with a definition of military power, when and how it should be used. From a large number of authors, “moral forces” are linked to “codes of conduct”, and the fundamental understandings about the “profession of arms”, based on “fiduciary trust”, “covenanted” service and professional and personal “conscience”. The article covers what authors have written about “culture” and the ethics of “technology” devices and systems, including “cyber” warfare. It concludes with recognition of the increase in ethical sensitivity in this century which is characterized by a phenomenon, the crises of “identity”, personal, national and global.     

防空兵群指挥所配置方案优化分析

防空兵群指挥所配置是兵力部署的重要内容,它从根本上决定了指挥所的指挥效能和野战生存能力。多年来,指挥所的配置多是根据防空兵战斗的相关战术原则,由作战参谋提出数个配置方案,然后由指挥员做出决策。这种仅凭主观决策的做法与现代防空作战的要求不相适应。结合模糊多指标评判方法与优化理论,从发挥指挥效能与提高生存能力两个方面出发,对防空群指挥所的配置进行了分析,并建立了配置方案优化的模型,从根本上改变了指挥所配置完全依赖主观判断的做法。最后应用模型分析了一个实例。

空袭模式的进化与防护技术的发展

通过分析空袭兵器、空袭历史、防空体系和防护技术的发展,将空袭模式划分为防区内(低空)地毯式打击、防区内(中低空)多手段打击、防区外陆海空三位一体精确打击三代。将防护体系划分为"边陲墙壕烽火台+腹地城池"、"防空系统+防护工程"两代。并预测了第四代空袭模式:防区外陆海空天四位一体全球快速精确打击和与之相对应的第三代"防空反导+信息化防护工程"防护体系。根据打击力和防护力相生相克的矛盾运动,提出了末端防护工程应吸收信息技术、发展综合防护技术,信息化时代的防护工程不仅要保护可以转入地下的目标,而且要保护无法转入地下的目标。从源头上为陆基目标防护的研究和建设提供参考和启迪。
