Occupying an observation post using SLOCTOP; identify the item that is NOT part of L-Location?

The correct choice emphasizes the importance of careful positioning in a tactical situation. When occupying an observation post, selecting a location is critical to maintaining cover and concealment while also ensuring effective observation capabilities. The item that is NOT part of L-Location underscores a misunderstanding of strategic positioning.

Choosing a position on the highest terrain may seem advantageous for detection, but it can also expose the observation post to being easily spotted by the enemy. The principle of avoiding a sky-lined position is crucial because such locations can reveal the team's presence and compromise their effectiveness. Instead, the focus should be on finding a position that balances height with the ability to remain concealed, ensuring the observation post functions effectively without attracting unnecessary attention.

In contrast, the other options correctly align with the principles of L-Location. Sending team location information to relevant units ensures situational awareness and coordination. Preparing an observation fan and making a terrain sketch helps maximize the team's observational capabilities by understanding the terrain features firsthand. Selecting a position that blends into the environment is a tactical necessity to preserve the element of surprise.
