What are the different firing positions for a mortar crew?

The correct choice regarding the different firing positions for a mortar crew highlights the importance of establishing both primary and secondary positions for effective mortar operations. The primary position is typically where the mortar crew conducts its primary duties, which include firing at targets. This position is chosen for its line of sight to intended targets and generally offers a good balance between cover and capability.

In contrast, the secondary position is crucial for operational security and flexibility. If the primary position becomes exposed or compromised, the mortar crew can quickly shift to the secondary position to maintain their ability to engage targets while avoiding enemy fire. This redundancy not only protects the crew but also ensures that they can continue to provide fire support even under threat.

Understanding the necessity of these positions allows mortar crews to operate more effectively in various combat scenarios, maintaining the element of surprise and ensuring that they can respond to dynamic battlefield conditions. The other options relate to different concepts, such as varying tactical approaches or positioning based on specific mission types, but don’t directly address the specific terminology as used in mortar operations for defining firing positions.
