Which of the following can cause a BTRY decertification?

A Battery (BTRY) decertification can occur when the primary Engagement Control Station (ECS) or Battle Control Post (BCP) crew is lost. This situation is critical because the ECS and BCP are essential components for command and control in missile defense operations. The loss of these crews can lead to a significant gap in the organization’s ability to execute missions effectively, maintain situational awareness, and respond to threats. Without these crews, the unit's operational readiness is compromised, potentially resulting in a failure to meet required readiness standards and, consequently, decertification.

Maintaining full crew capabilities and exceeding training requirements are both positive indicators of unit readiness. Successful mission completions also showcase the operational ability of the BTRY, reinforcing its capability rather than detracting from it. Therefore, losing the primary crews due to personnel changes, attrition, or other factors directly impacts the unit's ability to function and fulfill its mission, justifying decertification.
