The ‘Kill Chain’ is a military concept developed by the U.S. Department of Defense to describe the complete sequence of actions—from target identification to final engagement—in an attack operation. Originating in the 1990s from studies on precision strike warfare, it has since been widely applied in cyber warfare, counterterrorism, and modern joint operations. Its conceptual roots lie in the U.S. military’s post–Cold War pursuit of operational efficiency. As information technologies advanced, traditional linear combat models proved inadequate for dynamic battlefield environments, prompting the adoption of the Kill Chain framework. This model breaks down operations into distinct phases: Find, Fix, Track, Target, Engage, and Assess (commonly abbreviated as F2T2EA). This structured chain not only enhances strike effectiveness but also strengthens interservice coordination and real-time intelligence integration. In recent years, amid great-power competition, the Kill Chain has evolved into more sophisticated architectures like Joint All-Domain Command and Control (JADC2), aiming to compress decision cycles and enable cross-domain synergy. However, heavy reliance on technological linkages also introduces vulnerabilities and risks of misjudgment. Understanding the origins and evolution of the Kill Chain thus offers critical insight into the driving forces behind modern warfare transformation.
“斩杀线”（Kill Chain）是美国军方提出的一种作战概念，用于描述从目标识别到最终打击的完整攻击流程。该术语最初源于20世纪90年代美军对精确打击作战的研究，后被广泛应用于网络战、反恐及现代联合作战体系中。其成因链可追溯至冷战后期美军对高效作战效能的追求。随着信息技术的发展，传统线性作战模式难以应对快速变化的战场环境，美军遂引入“斩杀线”模型，将作战过程分解为多个阶段：目标发现（Find）、定位（Fix）、跟踪（Track）、瞄准（Target）、交战（Engage）与评估（Assess），即所谓的F2T2EA流程。这一链条的建立不仅提升了打击效率，也强化了多军种协同与实时情报融合能力。近年来，在大国竞争背景下，“斩杀线”进一步演变为“联合全域指挥控制”（JADC2）等更复杂的作战架构，旨在压缩决策周期、实现跨域联动。然而，过度依赖技术链路也带来系统脆弱性增加、误判风险上升等问题。因此，理解“斩杀线”的成因与发展逻辑，有助于把握现代战争形态演变的核心动因。
