A historical overview of US counter-insurgency

Say not the struggle naught availeth,

The labour and the wounds are vain,

The enemy faints not, nor faileth,

And as things have been, things remain.

复杂战场环境下的防空反导光学成像制导技术

光学成像制导技术是提升精确制导武器防空反导能力的核心技术之一,对提高复杂战场环境下精确制导武器的防空反导能力具有十分重要的作用。针对复杂战场环境下防空反导的需求,首先深入分析了各种复杂战场环境要素给光学成像制导武器带来的挑战,然后对未来光学成像制导技术发展趋势进行预测,最后结合我国光学成像制导技术发展现状,介绍了未来几年间需重点探索的几种新型光学成像制导技术。     

The Chinese and Asian impact on Russian nuclear policy

Asia, where nuclear powers already interact (including North Korea), exerts a growing influence on the thinking and policy underlying Russia's current and future nuclear (and overall defense) posture. China's rise is forcing Russia into a greater reliance on strategic offensive weapons and tactical nuclear weapons. These in turn will reinforce its opposition to US missile defenses, not only in Europe but also in Asia. Russia must now entertain the possibility of nuclear use in regional conflicts that would otherwise remain purely conventional. It cannot be postulated blindly that nuclear weapons serve no discernible purpose other than to deter nuclear attacks by other nuclear powers. The strategic equation in Asia and in the Russian Far East convincingly demonstrates the falsity of this approach. Nuclear weapons will be the essential component of Russia's regional defense policy if not of its overall policies – and this also includes contingencies in Europe.     

Are non‐lethal weapons a viable military option to strengthen the hearts and minds approach in Afghanistan?

Commanders of the International Security Assistance Force (ISAF) have repeatedly stressed the hearts and minds approach in Afghanistan, in saying that the human terrain is decisive for a successful outcome of the mission. Avoidance of civilian casualties is considered of strategic importance, and by nature highly dependent on the management of tactical level Escalation of Force (EoF) situations. Non‐lethal weapons (NLWs) are expected to enable tactical commanders to avoid innocent civilian casualties in such situations. This article considers a selected NLW on its potential to accomplish this requirement. It uses a defence technology assessment approach to analyse EoF situations experienced by Dutch ISAF forces in which the NLW is inserted. The analysis demonstrates that a range of contextual factors in the Afghanistan high‐risk environment tend to narrow down the window of opportunity for the NLW to help defuse the risk of unintended civil casualties.
