A _____ consists of a number of planned targets of a similar nature that are planned for sequential attack.

The concept of a sequence of planned targets that are intended for sequential attack is embodied in what is referred to as sequential targets. This term specifically implies that there are multiple targets recognized and organized to be engaged one after the other in a prearranged manner. This orderly and structured approach is crucial in military operations for maximizing efficiency and effectiveness during combat engagements.

While other terms may appear relevant, such as a "series of targets" or "program of targets," they do not capture the precise nature of a sequential attack as effectively as the term "sequential targets." Therefore, it is the clarity and specific application of the term in a tactical context that reinforces why sequential targets is the correct choice for describing this arrangement of planned engagements.
