What distinguishes the Fat Hawk from the Wet Hawk?

The distinction between the Fat Hawk and the Wet Hawk primarily pertains to their capabilities and roles in operations. The correct answer highlights that the Fat Hawk provides both fuel and ammunition, which underscores its multipurpose functionality in supporting missions. The ability to deliver essential resources such as fuel and ammunition enables the Fat Hawk to play a critical role in logistical support, extending the operational range and effectiveness of ground units and other aircraft.

In contrast, the other options do not accurately reflect this aspect of the Fat Hawk's design and function. For instance, while size could be a factor in distinguishing helicopters, it does not encapsulate the specific capabilities that set the Fat Hawk apart in terms of logistical support. Additionally, the notion that it can only perform maintenance tasks or is strictly for ground operations does not align with its versatile role in operational settings. Hence, understanding the multifunctional nature of the Fat Hawk solidifies why it is recognized for providing both fuel and ammunition as its distinguishing feature.
