What challenge does open terrain present for a patrol mission?

Open terrain poses a significant challenge for patrol missions primarily because it increases visibility, which enables enemy forces to spot the patrol more easily. In open areas with fewer obstacles such as trees, hills, or buildings, the available cover is limited. This lack of concealment makes it difficult for troops to move undetected, as their movements are more exposed to enemy observation.

Patrols must be more cautious and deliberate in their actions when traversing such environments, as the risk of being seen can lead to ambushes or other hostile encounters. On the other hand, open terrain often does not facilitate the effective application of specific military tactics that rely on cover and concealment, making stealth mode of operation significantly tougher.
