When should AT assessments be conducted before deployment?

The correct choice reflects the importance of conducting Anti-Terrorism (AT) assessments well in advance of deployment to ensure effective planning and implementation of security measures. Performing these assessments early allows for a thorough evaluation of potential vulnerabilities and risks associated with the deployment area. This proactive approach enables commanders and security personnel to devise strategies and allocate resources effectively to mitigate threats before personnel arrive.

By conducting assessments early, units can also integrate findings into their operational plans and make necessary adjustments to enhance the overall safety and readiness of deployed forces. This foresight not only assists in smooth logistics and coordination but also fosters a culture of vigilance and preparedness among all personnel involved.

The other options present less effective timelines for AT assessments. Conducting assessments just before deployment may not provide ample time to implement necessary measures. Assessing immediately after arrival can lead to gaps in security, as personnel will already be at risk. Waiting until the first month of deployment introduces vulnerability during a critical period when initial operations are underway, which could compromise safety and security.
