 Many sailors use social media to communicate with family and friends back home. To prevent enemies from using that information against us, sailors and family members need to know what they can and cannot post. So we have our critical information, which is our ship's movement, our port visit. We know that there's a threat. We know that we're vulnerable to all sorts of different ways. And the risk of that is whether or not when we pull into port that an adversary can take action on us. Like cause harm, like cause some sort of attack. USS Cole can be used somewhat as an example, although in the whole OPSEC process it may not work, but our adversaries knew that the USS Cole was going to be there and they took action against us. The Navy wants to try and prevent tragic events like the Cole. By practicing sound OPSEC, we can do our part to protect that information to the ship and keep adversaries off guard.
