What guideline should Army personnel follow when engaging in online activities?

The guideline that Army personnel should follow when engaging in online activities is to "Think, Type, and Post." This principle emphasizes the importance of careful consideration before sharing information online. It encourages individuals to reflect on the potential impact of their words, ensuring that their online presence aligns with the values and standards of the Army.

By promoting a thoughtful approach, this guideline helps prevent the dissemination of inappropriate or harmful content, which could negatively affect both the individual and the Army as a whole. It fosters a culture of responsibility and awareness regarding the implications of online interactions, which is critical in a military setting where reputation and discipline are paramount.

In contrast, the other options suggest practices that could lead to careless or unconsidered online behavior. Posting without thought can result in misunderstandings or breaches of protocol, while relying solely on a supervisor's approval before posting may not foster independent judgment. Additionally, limiting posts to duty hours may unnecessarily restrict engagement, as relevant conversations and information sharing can occur outside those hours.
