During what phases of an operation must OPSEC principles be applied?

OPSEC principles must be applied during all phases of an operation because operational security is crucial throughout the entire lifecycle of a mission. This ensures that sensitive information is protected at every stage, starting from the planning phase, through execution, and continuing into the review phase.

During the planning phase, OPSEC helps identify vulnerabilities and allows for the development of strategies to mitigate risks associated with leaked information. In the execution phase, it focuses on maintaining the security of operations, ensuring that actions taken are not compromised by adversaries having knowledge of plans or troop movements. Finally, during the review phase, lessons learned can be analyzed to strengthen OPSEC measures for future operations.

This comprehensive application of OPSEC is vital to avoid potential threats and safeguard mission success.
