What is indirect fire and how can it affect Air Assault missions?

Indirect fire refers to artillery or mortar fire that is delivered from a distance, typically outside the immediate area of engagement. This type of fire can have significant implications for Air Assault missions. Since helicopters often operate at low altitudes and are highly susceptible to enemy fire, the presence of indirect fire can create considerable risks for these aircraft during transport or troop insertion.

When artillery or mortar shells land in proximity to the operation area, they can not only endanger the helicopters themselves but also threaten the safety of the personnel being deployed or extracted. Moreover, the unpredictable nature of indirect fire can complicate mission planning and execution, as pilots must consider the possibility of incoming rounds when determining flight paths and operational timing.

In contrast, the other options focus on different forms of military engagement that generally occur at a closer range or involve more precision targeting. Guided missile strikes and close air support from aircraft are typically direct engagements with a defined target, while direct artillery fire is aimed at easily observable targets. Although all forms of fire support play important roles in air operations, indirect fire's potential to disrupt Air Assault missions due to its area effect creates unique challenges that must be addressed in planning and operational risk assessments.
