What is the definition of "indirect fire"?

Indirect fire is defined as fire delivered on a target that is not visible to the firer. This type of fire is typically used in artillery and mortar systems, where the projectile is launched in a high arc, enabling it to strike targets that are obscured by terrain or other obstacles. The ability to engage targets without having a line of sight is crucial for effective military operations, especially in complex environments where direct visibility is limited.

In contrast, fire aimed at a target that is visible to the firer would be classified as direct fire, which allows for precise targeting. Fire aimed specifically at ground troops typically falls under the category of direct fire as well. Similarly, fire used for signaling is unrelated to the definition of indirect fire, as it serves a different purpose entirely. Understanding the distinction between direct and indirect fire is essential for effectively employing artillery and mortars in combat scenarios.
