What advantage do drones provide in mapping for offensive engineering?

Drones provide the advantage of offering high-resolution imagery over large areas, which is crucial in the context of offensive engineering. This high-resolution imagery enables engineers and planners to obtain detailed geographical data, allowing for accurate assessments of terrain and infrastructure. The ability to cover expansive areas swiftly while maintaining clarity in the imagery is essential for effective mapping, as it supports informed decision-making.

While other options mention potential benefits such as long flight times, the capability to carry heavy equipment, or lower operational costs, these factors are not the most significant advantage when it comes to mapping specifically. In offensive engineering, the quality and detail of the data collected for terrain analysis or reconnaissance are paramount, making high-resolution imagery the standout feature that drones can provide in this context.
