Should an observer continually update their terrain sketch?

An observer should continually update their terrain sketch because the dynamic nature of the battlefield can alter the tactical situation frequently. An accurate and up-to-date terrain sketch is crucial for effective communication and situational awareness. Continuous updates ensure that all relevant features, such as enemy positions, tactical landmarks, and recent changes in the environment, are captured and represented. This facilitates better coordination with supporting elements and enhances the overall effectiveness of fire support operations.

Additionally, a continually updated terrain sketch allows the observer to make informed decisions in real-time, accounting for the evolving operational landscape. It aids in planning fire missions, adjusting targets, and responding to changes in the enemy's actions. This proactive approach ensures that the observer remains aware of current conditions, enhancing their ability to provide accurate and timely fire support.

In contrast, options suggesting updates only when instructed or for new missions do not account for the necessity of real-time situational awareness, which can be critical in rapidly changing combat environments.
