What are the two types of firing modes for the mortar system?

The correct answer highlights the appropriate firing modes that are vital for effectively operating a mortar system. The mortar can be classified into two main modes of operation: direct and indirect.

In direct fire mode, the mortar is aimed directly at the target, allowing for immediate and precise engagement, which is typically used for closer, visible targets. This mode requires the operator to have a clear line of sight to the target. Conversely, in indirect fire mode, the mortar is aimed at a high angle, and the projectile is fired over obstacles to reach the target. This is particularly useful for engaging targets that are not in direct line of sight or are located behind cover.

Understanding these firing modes is crucial for effective tactical operations as they inform the use of the mortar in various combat scenarios, ensuring that operators choose the most appropriate method based on the situation at hand.
