What is a running estimate?

A running estimate is best understood as an ongoing assessment that helps military leaders evaluate the current operational situation. This assessment is continuously updated based on new information, changes in the environment, and the outcomes of previous actions. It is a critical element in the Military Decision-Making Process (MDMP) as it provides situational awareness and allows leaders to make informed decisions throughout an operation.

In contrast, the other options refer to different aspects of military operations that do not capture the full utility of a running estimate. A summary of completed training focuses on evaluating the effectiveness of training exercises rather than providing a dynamic situational overview. An assessment of past operations may offer insights into previous actions but does not inform current conditions in real-time. A tool for mission briefing is useful for communication during operations but does not represent the continuous, analytical nature of a running estimate, which is geared towards current and future operational adjustments.
