Revisiting the justification for an all-volunteer force

In 1968, President Nixon established the Commission on an All-Volunteer Armed Force, or the Gates Commission, which served as the impetus and justification for an All-Volunteer Force (AVF). At the end of its deliberations, the commission recommended abolishing the draft and transforming the U.S. military into a force of volunteers beginning in 1973. Interestingly, the debate regarding the merits of both systems appeared to be largely economic – with cost–benefit analysis playing the primary role. Lately, we are beginning to see a new, politically-motivated impetus for returning to a “system of national service.” The ideas spurring this debate are many: the need to reaffirm the nation state, the commitment of citizens to the state, political ownership and oversight of the forces, the need for social equity in serving the nation, limiting the support for armed conflict by burden-sharing among citizens, and equitably spreading the personal cost of war.     

基于云模型的导弹信息作战指挥效能评估

针对导弹信息作战指挥效能评估中既包含定量指标,又包含定性指标,而对这些指标进行科学合理地统一评价尚存在很多困难的问题,运用云模型对其进行了研究。分析了导弹信息作战指挥能力的指标体系,介绍了云模型的相关理论,并给出了运用云模型进行效能评估的详细算法,利用云发生器得到了最终的评估结果。最后给出了一个评估实例,结果证明该方法有效可行,能很好地解决效能评估中定性语言到定量值之间的转化问题。

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.
