What type of munitions operates effectively from 300 to 3000 feet?

Cluster bombs are designed to disperse multiple smaller explosive submunitions over a wide area, making them effective against dispersed targets. Their effectiveness from a range of 300 to 3000 feet is attributable to their ability to cover a vast area upon detonation. When deployed at the specified altitudes, cluster bombs can maximize their impact, delivering submunitions over a broader area to engage multiple targets simultaneously.

In contrast, missiles often have different operational parameters and are generally designed to be launched from greater distances. Smart bombs and guided munitions typically require precision guidance, meaning they operate more effectively over shorter ranges where accuracy is paramount. Thus, while guided munitions might include laser-guided weapons that could operate within similar altitudes, their primary function and design focus do not necessarily align with the operational effectiveness of cluster bombs across that entire altitude spectrum.
