What is a primary distinction between indirect fire and direct fire support?

Indirect fire support is characterized by its ability to engage targets without a direct line of sight to the target, which is a fundamental aspect of the difference between it and direct fire support. In indirect fire, projectiles are launched at high angles and follow a ballistic trajectory, allowing them to hit targets that are obscured from view due to terrain or other obstacles. This capability is crucial in many combat situations, enabling forces to strike at enemy positions while remaining concealed or protected.

The need for indirect fire to support tactics often arises in complex battlefield environments where visibility is compromised, and enemies may be using terrain features for cover. This makes option C the definitive choice, as it highlights the significant operational advantage provided by indirect fire support in terms of flexibility and range.

While it is true that indirect fire support does often require specialized equipment, such as mortars or artillery systems, this aspect alone does not encapsulate the primary distinction. Accuracy can also vary in both types of fire, depending on various factors, but it does not define the fundamental difference between the two. Direct fire is not limited exclusively to trained marksmen, as many personnel can engage in direct fire with different weapon systems. Thus, the ability of indirect fire to operate without requiring a clear line of sight is
