What is the “kill chain” in relation to the DIDEA process?

The "kill chain" in relation to the DIDEA process refers to a detailed sequence of actions that begin with target identification and culminate in engagement. This concept emphasizes the step-by-step nature of direct fire engagement, which includes detecting a target, identifying its nature, deciding on an appropriate response, and executing the engagement. Understanding the kill chain is crucial for effective operational planning and execution, as it ensures that each phase in the process is properly addressed to achieve successful outcomes while mitigating risks. This structured approach helps to streamline decision-making and improve operational effectiveness on the battlefield.
