What types of military information are considered sensitive?

The correct choice identifies military information that poses a risk if accessed by adversaries, specifically relating to capabilities that could facilitate opposition actions against the U.S. military. This type of sensitive information encompasses operational tactics, technical specifications of weapons systems, or intelligence on military strategies that could enable adversaries to anticipate or counter U.S. military operations. Thus, safeguarding this information is critical to maintaining operational security and a strategic advantage.

Other types of information, while they may have their own importance, do not fall under the same categorical risk as those described in the correct option. General training protocols, personal details about service members, and non-classified logistics information do not directly provide adversaries with actionable intelligence that could undermine U.S. military effectiveness or safety. Therefore, the emphasis on protecting information that could potentially enhance enemy capabilities underscores the core purpose of military information sensitivity standards.
