What is the first principle in the fundamentals of security?

The first principle in the fundamentals of security is to maintain enemy contact. This principle emphasizes the importance of having continuous awareness of enemy movements and intentions. By keeping track of enemy forces, a commander can make informed decisions and adjust their strategies accordingly. This practice enhances overall situational awareness and allows for timely responses to potential threats.

Maintaining contact with the enemy enables a better understanding of their capabilities and plans, which is crucial for effective defense and operational planning. It also helps to create a proactive stance rather than a reactive one, ensuring that forces are prepared for engagement rather than caught off-guard. In essence, this principle underpins the other fundamentals of security by providing the necessary intelligence and insight into enemy actions.
