What is the primary focus of the fundamentals of security?

The primary focus of the fundamentals of security is to control the battlefield environment. This concept involves ensuring that friendly forces maintain awareness of potential threats and the movement of enemy forces, which allows for informed tactical decisions and the ability to react effectively to enemy actions. Establishing a strong defensive position is part of maintaining security, but the overall goal is to create conditions that allow for the protection of one's forces while denying the enemy any advantages.

Maintaining enemy contact includes gathering intelligence, which is critical for effective mission planning and execution, but it does not encompass the full scope of security. Defeating enemy forces is an outcome or objective rather than a focus. Security serves as a proactive measure that enables forces to operate effectively on the battlefield, ensuring they can respond to threats and exploit opportunities as they arise.
