Which factors contribute to difficulties in Environmental conditions?

The selected answer highlights critical factors that can severely impact operational effectiveness in military and tactical scenarios. Wind influences projectile trajectory, making it challenging to accurately hit targets at varying distances. Angled firing refers to engaging targets that are not at a direct line of sight, complicating the aim and necessitating adjustments. Limited visibility can result from a variety of factors including darkness, fog, or obstructions, which hinders situational awareness and the ability to engage effectively with the environment.

These elements collectively represent environmental conditions that significantly affect both planning and execution of operations. Thus, understanding and adapting to these factors is crucial for achieving mission success and ensuring the safety of personnel during engagements.
