What is the recommended distance mortars should be placed from friendly units?

The recommended distance mortars should be placed from friendly units is one-half to two-thirds of their range. This distance ensures a safe buffer zone that minimizes the risk of friendly fire while allowing for effective support of ground troops. Mortars have a unique trajectory and can be affected by various factors including wind and terrain, so maintaining this distance helps ensure that the rounds land safely.

This distance also allows for operational flexibility, enabling mortars to adjust firing angles and trajectories without compromising safety. By positioning mortars at this range, commanders can effectively use them to support their units while maintaining a high level of situational awareness and control over the battle space.

The other options suggest distances that are either too close or too far. Being too close could increase the risk of unintended casualties or damage to friendly forces, while being too far could negatively impact the responsiveness and integration of mortar fire support into the maneuvers of friendly units. Hence, the range of one-half to two-thirds aligns with tactical best practices for utilizing mortars in a combat environment.
