Which operation orients on the force or facility being protected?

The focus of the operation that orients on the force or facility being protected is specifically associated with Force Protection. This concept encompasses measures that are designed to safeguard military personnel, equipment, and facilities from potential threats and attacks. It involves a comprehensive approach, including security assessments, physical security measures, intelligence gathering, and risk management strategies to protect against both external and internal threats.

In the context of a military operation, Force Protection is critical because it directly deals with the preservation of combat power and the effectiveness of military operations. By ensuring that personnel and facilities are secure, a military unit can maintain readiness and operational effectiveness.

While Security Operations relate to the broader aspect of securing an area or an operation, they do not specifically target the protection of a particular force or facility as their primary orientation. On the other hand, Passage of Lines and Signaling Operations pertain to tactical movements and communication respectively, which are not focused specifically on protective measures. Thus, the correct answer is rooted in the specific mission of Force Protection as it directly involves safeguarding the forces and facilities under threat.
