What type of target does a target of opportunity refer to?

A target of opportunity specifically refers to targets that are not pre-planned, meaning they are identified and engaged in the moment based on situational awareness and immediate circumstances. This could occur when a unit encounters a target unexpectedly during operations that was not included in the prior targeting plans or assessments.

The essence of this concept revolves around flexibility and responsiveness in combat situations. Targets of opportunity can include a wide range of enemy assets or personnel that present themselves unexpectedly, thus allowing the engaging force to capitalize on immediate tactical advantages.

In contrast, focusing on specific attributes—such as whether a target is stationary or under surveillance—does not fully capture the essence of a target of opportunity. Those aspects may characterize certain targets, but they do not define the core principle that a target of opportunity arises spontaneously, based on real-time conditions rather than from advance planning or strategic designation.
