What is considered the first layer of defense for an Entry Control Point (ECP)?

The first layer of defense for an Entry Control Point (ECP) is the contact sentry. This role is critical as it involves the personnel who are tasked with identifying and assessing any individuals or vehicles that approach the ECP. The contact sentry has the initial responsibility to enforce access control measures, making determinations on who is allowed entry and who may present a potential threat.

By managing these entry protocols, the contact sentry sets the tone for security at the ECP, ensuring that proper identification and checks are conducted before allowing access. This position acts as the initial screening mechanism, essential for maintaining the security posture of the area being protected.

While other roles like cover sentries, weapons teams, and scouting units contribute to the overall security measures at an ECP, they function as additional layers of defense, primarily focused on broader security measures or response capabilities in case of an incident. The contact sentry’s role is foundational, making it the essential first layer in managing entry at an ECP.
