According to General Order 2, how should one walk their post?

Walking your post in a military manner, always alert, reflects the discipline and seriousness of duty that is essential in the Coast Guard. This approach emphasizes the importance of maintaining situational awareness and readiness to respond to any circumstances that may arise. It involves a posture of vigilance, ensuring not only personal safety but also the security of the area being patrolled.

Being alert helps in recognizing any potential threats or changes in the environment that could impact the mission or the safety of personnel. It also fosters a sense of responsibility and professionalism, essential qualities in a military setting where attention to duty can significantly affect outcomes.

The other options, while they may carry certain merits in a more relaxed context, do not encompass the gravity and necessary alertness stipulated by General Order 2. Casual walking lacks the focus required for maintaining security, while communicating with others can distract from the primary responsibility of observing and reporting. Walking with attention to detail is important but does not fully encompass the overall mindset of military readiness highlighted in the correct answer.
