Jungle operations are characterized by dense vegetation, high temperature, high humidity, and heavy rain. Army aviation significantly enhances combat operations in jungle areas. Artillery fire can be difficult to observe and adjust. Thick foliage and rugged terrain reduce the range of radio communications. Hot, humid tropical air decreases aircraft lift capabilities.
Weather is subject to rapid and violent change.
Problems with corrosion are intensified, thereby increasing demands on spare parts and maintenance. Aviation forces can operate effectively in desert environments. Desert terrain often allows aircraft to engage targets at the maximum range of their weapons systems. However, aircraft are vulnerable to enemy long-range observation and detection because of inadequate cover and concealment. High daytime temperatures decrease lift capabilities.
