Under what conditions should a linear sheaf be requested?

A linear sheaf should be requested under specific conditions that facilitate its effective use in targeting. The correct choice indicates that a linear sheaf is appropriate when the target area is greater than 200 meters in length but no wider than 200 meters. This is important because linear sheaves are particularly effective for engaging longer, more extended areas such as troop formations, vehicles, or geographic features that span a significant distance.

When a target area is over 200 meters long, a linear sheaf dispersion allows for a spread of fire that is designed to cover the elongated shape of the target while minimizing the risk of collateral damage to areas outside the designated target zone. The limitation of width to 200 meters ensures that the fire remains concentrated enough to effectively engage the target without unduly affecting adjacent areas.

In contrast, conditions like being less than 200 meters in length or equal to 200 meters do not align with the operational range suited for a linear sheaf, while a target greater than 300 meters in length could exceed the effective range and capability of the munitions typically used in such configurations. Thus, understanding the optimal conditions for deploying a linear sheaf is key to effective target engagement.
