What operational feature does the SENTINEL provide regarding speed?

The SENTINEL system is designed with operational efficiency in mind, and one of its key features relates to its optimal maximum transportation speed. This is crucial in ensuring that air defense units can rapidly reposition themselves as needed in response to evolving threats. The system's design allows for effective transport and mobility, allowing air defense assets to be quickly moved to strategic locations, thereby enhancing the overall effectiveness of air defense operations.

While high-speed radar operations and quick deployment are important features of the SENTINEL, they primarily focus on functionality rather than the transportation aspect. Ground-to-air communication speed involves the exchange of information but does not directly relate to the physical movement of the system. Optimal maximum transportation speed directly affects the ability of air defense forces to maintain operational readiness and respond dynamically to air threats, reinforcing the importance of choice B.
