Which of the following is true regarding mortar crew operations?

The statement about mortar crew operations being reliant on coordination and communication for effective operation is accurate and highlights a critical aspect of mortar employment. Mortar crews consist of multiple members who have distinct roles, such as the gunner, assistant gunner, and ammunition bearers. Effective operation of mortars involves the seamless execution of these roles, which requires constant communication among the crew members to ensure that they understand their tasks and timing.

Additionally, communication is essential for adjusting fire based on feedback from observers, ensuring accurate targeting, and maintaining situational awareness during operations. The crew needs to work together to calculate data, manage ammunition, and safely coordinate firing sequences, making coordination and communication paramount for mission success.

Other options don't accurately reflect the reality of mortar operations. For instance, while experience is beneficial, personnel can be trained to operate mortars effectively regardless of their prior experience. Mortar crews do not operate in isolation; they work closely with infantry and other units on the battlefield for support. Lastly, mortars can be quite effective in urban environments, where they provide indirect fire support while minimizing gun exposure and maximizing the ability to fire in confined spaces.
