The Vietnam Conflict pointed out the need for a revised doctrine, specifically one based on what?

The correct answer emphasizes the necessity for a whole-base protective system, which emerged from the lessons learned during the Vietnam Conflict. This conflict highlighted vulnerabilities in base security and the need to create a comprehensive approach that integrates various security measures to protect military installations.

A whole-base protective system encompasses a combination of physical security barriers, surveillance technologies, command and control infrastructure, and personnel training aimed at mitigating risks to the entire base, rather than focusing solely on individual components or tactics. In Vietnam, the complexity of threats faced, including guerrilla warfare and unconventional combat strategies, underscored the inadequacy of existing protection frameworks, prompting military leaders to rethink and enhance base security protocols.

Other options, like air superiority and joint operations, while important components of military strategy, do not specifically address the immediate defensive needs highlighted by the Vietnam experiences in terms of protecting ground installations. Mobile ground tactics also represent a tactical evolution stemming from the conflict, but they do not encapsulate the comprehensive protective strategies required for the safety of entire base environments.
