What type of operation orients on the force or facility being protected?

The correct answer is that security operations orient on the force or facility being protected. Security operations are conducted to ensure the safety and integrity of military assets, personnel, installations, or equipment. They involve measures designed to deter threats and risks, thereby enhancing the overall security posture of the designated area or force.

Security operations typically include surveillance, reconnaissance, and the establishment of defensive positions, all of which focus on safeguarding resources from potential enemy actions. These operations are critical in maintaining operational readiness and effectiveness in missions, as they allow forces to operate with a higher degree of safety.

In the context of the other choices, while passage of lines involves coordinating movements and access across lines that may be contested, and signaling operations are related to communication methods within and among units, neither specifically focuses on protecting a force or facility in the same way as security operations do. Force protection, while also related to safeguarding personnel and assets, is a broader concept and includes measures that go beyond the operational scope of security operations, tying in aspects like force posture, intelligence, and policy.
