Which tactic is considered in the Extended Observation Post (OP) Emplacement?

The correct answer is the use of unexpected sites in the context of Extended Observation Post (OP) Emplacement. This tactic is crucial for maintaining the element of surprise and achieving effective reconnaissance. Utilizing unexpected sites allows Scouts to gather intelligence while minimizing the risk of detection by adversaries. By positioning themselves in locations that are not immediately obvious or predictable to the enemy, Scouts can observe movements and activities without drawing attention to their own presence.

This tactic complements the overall strategic goal of maximizing observation capabilities while ensuring safety. Effective use of unexpected sites can lead to more advantageous insights, contributing to informed decision-making for unit leaders.

While the selection of high ground, avoiding sides of hills, and ensuring isolation from all routes are all relevant considerations in a reconnaissance strategy, they are often not as impactful as choosing unexpected sites. High ground selection, for instance, can sometimes make an observer more predictable, while avoiding hills or isolating routes may limit visibility and situational awareness. Therefore, while these factors are certainly important, employing unexpected sites stands out as a more tactical advantage in establishing an observation post.
