Which of these might indicate unusual interest in security concepts?

Seeking expertise in military tactic training can indicate an unusual interest in security concepts because it demonstrates an active engagement with specific strategies and methodologies commonly associated with security and defense. This level of interest goes beyond casual awareness or discussion; it reflects a desire to obtain specialized knowledge and skills that can be directly applicable to security operations. Such training often involves understanding complex tactical principles, operational planning, and the application of these tactics in various scenarios, which is indicative of a deeper commitment to the field.

While reading security-related news articles, engaging in military strategy discussions, and participating in public safety meetings all show some level of interest in security concepts, they do not necessarily reflect the same depth of engagement or initiative as actively seeking training in military tactics. The latter suggests a proactive approach to understanding and possibly implementing security measures in real-world situations.
