Which aspects are considered under weather in military operations?

The correct answer identifies visibility and wind as key aspects of weather in military operations. Weather plays a crucial role in influencing various operational factors, with visibility being essential for reconnaissance, targeting, and navigation. Poor visibility can significantly hinder movement and engagement with enemy forces. Wind also affects operations in multiple ways, including the trajectory of projectiles, the effectiveness of smoke screens, and the dispersal of chemical agents, which can change how units maneuver and fight.

Terrain and elevation, while important, relate more to physical aspects of the operational environment rather than directly to weather conditions. Enemy activity and morale pertain more to the psychological and strategic dimensions of combat rather than atmospheric influences. Similarly, combat readiness and logistics are critical operational considerations but are not classified under weather factors. Thus, visibility and wind are the direct weather elements that significantly impact execution and effectiveness in military operations.
