What method of engagement involves a sequence of shells being fired on the target area?

The method of engagement that involves a sequence of shells being fired on the target area is known as Continuous Fire. This approach is designed to create sustained fire on a target, allowing multiple rounds to be fired in succession with minimal interruption. The primary purpose is to achieve a high volume of fire over the target area, maximizing damage and effectiveness against targets that require consistent and relentless bombardment.

In the context of Close Air Support or artillery operations, Continuous Fire is particularly useful when targeting areas where the enemy is likely to sustain their position or when cover is minimal. The method ensures that the fire will continue until the command is given to stop or change the engagement.

The other methods mentioned, while they have specific uses, do not focus on the sustained and uninterrupted fire characteristic of Continuous Fire. Time on Target, for instance, emphasizes synchronization of rounds landing at the same moment rather than continuous delivery. Coordinated Illumination focuses on providing illumination for visibility, rather than the volume of fire. Repeat may imply repeating a previous command but is not a standard method of engagement like Continuous Fire.
