Which of the following is a recommended action during suspected jamming?

The recommended action during suspected jamming is to continue with normal communication while implementing authentication procedures. This approach allows for maintaining lines of communication and ensuring that, even under challenging circumstances, important messages can still be relayed. By authenticating, operators can distinguish between legitimate communication and potential threats, helping to mitigate risks associated with jamming.

In situations of jamming, it is important to not abruptly change operations or frequencies without certain confirmation. This can lead to confusion and disrupt coordination further. Therefore, persisting with normal communication while verifying the integrity of the messages is a sound tactic in managing the situation effectively.
