Commanders ensure operational security (OPSEC) is practiced during all phases of operations. OPSEC is a capability that identifies and controls critical information, indicators of friendly force actions attendant to military operations, and incorporates countermeasures to reduce the risk of an adversary exploiting vulnerabilities. As adversary analysts apply more information to an analytical model, the likelihood increases that the analytical model will replicate the observed force. Thus, current and future capabilities and courses of action can be revealed and compromised.
