The FARC’s militaristic blueprint

This article intends to explain the outstanding sequence of success and failure exhibited by the FARC, the main Colombian guerrilla since the 1980s. It claims that such sequence is unintelligible unless the adoption by the FARC of a militaristic organizational blueprint at its 1982 7^th Conference is taken into account. By building itself like an army, the FARC could boost its combat capacity, maintain its structural integrity, and develop powerful mechanisms that held the whole structure together. At the same time, the militarization of the FARC also entailed significant risks and costs like political isolation and high personnel turnover. After describing the militaristic blueprint, the article compares the FARC with other irregular forces that operated in the Colombian context – a comparison which is important to understand the specificity of the FARC trajectory, as well as the benefits and costs involved in it. The analysis highlights the critical role of organizational dimensions in the explanation of civil war outcomes, and suggests that at least for some problems organizational dynamics should be observed at a low level of granularity.     

Analysis of artillery shoot‐and‐scoot tactics

Firing multiple artillery rounds from the same location has two main benefits: a high rate of fire at the enemy and improved accuracy as the shooter's aim adjusts to previous rounds. However, firing repeatedly from the same location carries significant risk that the enemy will detect the artillery's location. Therefore, the shooter may periodically move locations to avoid counter‐battery fire. This maneuver is known as the shoot‐and‐scoot tactic. This article analyzes the shoot‐and‐scoot tactic for a time‐critical mission using Markov models. We compute optimal move policies and develop heuristics for more complex and realistic settings. Spending a reasonable amount of time firing multiple shots from the same location is often preferable to moving immediately after firing an initial salvo. Moving frequently reduces risk to the artillery, but also limits the artillery's ability to inflict damage on the enemy.

一种改进遗传算法在UCAV快速航迹规划中的应用

针对无人作战飞机(Unmanned Combat Aerial Vehicle,UCAV)航迹规划约束条件复杂、不确定因素多、实时性要求高的特点,提出了一种基于Voronoi图和改进遗传算法的快速航迹规划方法。该方法采取分层航迹规划的思想,首先根据Voronoi图生成初始航迹,并综合考虑约束条件,赋予各条航迹相应的权值;然后应用改进的遗传算法在生成的航迹空间中寻优,最终得到满意的航迹。该算法利用多处理机并行计算技术对传统遗传算法进行改进,大大缩短寻优时间。仿真结果表明基于Voronoi图和改进遗传算法的航迹规划提高了实时性,增强了UCAV的动态战场适应能力和突发威胁应对能力。
