_____ normally produces the specific effect on a target with the minimum expenditure of ammunition.

The concept of massing fires refers to the concentrated application of artillery or other related combat assets to achieve a desired effect on a target. This approach is strategically significant because it allows for the efficient use of resources, minimizing ammunition expenditure while maximizing impact. By concentrating firepower, a unit can effectively neutralize or destroy a target with fewer rounds and less risk of collateral damage.

This principle emphasizes the importance of precision and efficiency in combat operations, where the objective is to ensure that the fire supports the mission while conserving ammunition and reducing logistical burdens. In contrast, the other options may focus on broader planning, coordination, or effects but do not encapsulate the same focused approach toward achieving a specific military objective through the optimal use of firepower.
