What is the main challenge associated with a dispersed attack?

A dispersed attack involves multiple units engaging the enemy from various locations, which can lead to significant challenges in coordination. The primary challenge is ensuring that all units are synchronized in their actions, which can be complicated due to the distances between them and the potential for communication breakdowns. Effective timing and situational awareness are critical in such scenarios, as any lapse can result in a failure to achieve the desired tactical outcomes. Without proper coordination, units may act independently and, consequently, may not support one another effectively, rendering the attack less impactful.

The other options highlight alternative difficulties but do not encapsulate the essence of a dispersed attack as effectively. For instance, while engaging the enemy directly can be more challenging in a dispersed formation, it is not the defining characteristic of the coordination issues experienced. Additionally, the need for large troop deployments and logistics concerns are aspects that apply more generally to military operations but do not specifically pertain to the unique challenges faced in executing a dispersed attack.
