Final answer:
Discussions regarding military strategy or tactics and related equipment must be conducted securely to maintain operational security and ensure the effectiveness of military operations.
Step-by-step explanation:
Discussions about strategy/tactics or video of weapons, protective equipment, or tactical deployments must be conducted in a secure location. This is because such discussions can include sensitive or classified information that could compromise the safety and efficacy of military operations if made public. Historical and modern military strategies, such as those reflected in quotes from various sources, highlight the importance of secrecy and the adaptation to variable circumstances in warfare. The effective application of these principles is essential for maintaining operational security and achieving victory in conflict situations.
