Controlled warfare: how directed-energy weapons will enable the US Military to fight effectively in an urban environment while minimizing collateral damage

US military operations are increasingly conducted within urban environments and with these operations come the risk of increasing the number of civilian casualties and infrastructure damage. The use of non-lethal weaponry, such as directed-energy weapons, is one method for minimizing collateral damage. This method enables US military forces to effectively fight within urban environments through force escalation capabilities. Using a series of historical examples and future scenarios for urban warfare, this article highlights deficiencies affecting military capabilities in military urban operations, addresses the consequences of collateral damage, assesses the effectiveness of directed-energy weapons in military urban operations and encourages further funding, research and integration of non-lethal weaponry, such as directed-energy weapons, within the US military.     

Counterinsurgency force ratio: strategic utility or nominal necessity

As a consequence of intervention in Iraq and Afghanistan, force ratio for counterinsurgency (COIN) has come under increased scrutiny. Reduced to its essence, the issue is simply, ‘How many troops does it take to get the job done?’ This answer has been sought by the US military, academia, and think tanks. There have been numerous responses, culminating in several ‘plug-and-play’ equations for minimum force ratios in COIN operations. Due to the impossibility of determining precisely how many insurgent forces there are, it has become common to base force ratios on the population of the country. In the realm of policy, the question above is posed as, ‘How many of our troops does it take to get the job done?’     

光纤陀螺温度场分析及结构优化设计

从导热微分方程出发,建立了光纤陀螺温度场有限元模型,对模型进行了稳态温度场和瞬态温度场仿真分析。利用铂电阻测温电路对仿真结果进行实验验证,两者相对误差小于3%,证明仿真分析的结果是正确和有效的。针对光纤环温度场分布不均匀的情况,对光纤陀螺结构进行了优化设计。光纤陀螺在25℃环境中稳定工作时,稳态温度场分析结果表明,优化设计后光纤环最高与最低温度差为0.05℃,较优化前的0.19℃减小了73.7%;将陀螺置于60℃环境且处于非开机状态时,10min瞬态温度场分析结果表明,优化设计后光纤环最高与最低温度相差0.11℃,较优化前的0.19℃减小了42.1%。
