Humanitarian operations may pose challenges to which armed forces prepared for warfighting seem rather ill-equipped. It is the aim of this article to examine in what way military ethics should be adapted to humanitarian tasks. Two ideal types of military ethics are defined here: warfighting and humanitarian. The warfighting ethic is supposed to maximise the utility of the military in war and combat and to that end utilises the virtues of loyalty and honour. In contrast, humanitarian obligations require to a larger extent the development of personal integrity and an ability to follow one’s own conscience. The adaptation of military ethics is demonstrated in the case studies of the UK armed forces and the German Bundeswehr. Whereas the moral code of the UK armed forces remains anchored in the principles of the warfighting ethic, the case of the Bundeswehr presents a military ethic closely approximating the humanitarian ideal type. 相似文献

The performance of a laser weapon system based on coherent beam combining (CBC) depends on its propagation properties in the atmosphere. In this study, an analytical model based on partial coherent beam combining (PCBC) for assumed coherence coefficients between beams in a CBC lattice was developed. The Kolmogorov model of atmospheric turbulence and the Hufnagel-Valley model of Cn2 dependence on atmospheric parameters were implemented. Novel simplified metrics were proposed to assess the CBC performance. Several beam profiles (super-Gaussian, truncated Gaussian, etc.) and ge-ometries were analyzed in terms of maximal intensity in the far field. An approximate formula for PCBC efficiency dependent on the Fried radius was proposed. The results of CBC modeling were compared to those of the Gaussian beam propagation model in a turbulent atmosphere. The dependence of CBC performance on the Cn2 parameter, range, and elevation angle was analyzed. It could be concluded that the application of CBC for medium and long range propagation is impractical without an effective adaptive optics system. 相似文献
