What is one major advantage of using mortars over other artillery systems?

The choice highlighting portability and ease of setup captures a significant advantage of mortars over other artillery systems. Mortars are generally lighter and more compact than traditional towed artillery or howitzers, making them easier to transport for infantry units. Their design allows for quick deployment in various terrains, which is essential in combat situations where mobility and responsiveness are critical.

Moreover, mortars can be set up and fired much quicker than larger artillery pieces, which often require more extensive logistics and setup times. This capability allows troops to establish a firing position rapidly, providing immediate support in dynamic battlefield conditions.

Considering the other options, while greater range, higher rates of fire, and minimal training may be desirable features in different contexts, the distinctive advantage of a mortar’s portability and straightforward setup makes it particularly valuable for ground forces needing to adapt to changing situations quickly.
