True or False: Under ICS, radio codes are used for efficient communication.

The correct stance on the usage of radio codes under the Incident Command System (ICS) is that they are generally discouraged or not used to promote clear and efficient communication during incidents. The ICS emphasizes plain language communication to avoid confusion, especially in high-stress situations where individuals from various agencies or jurisdictions may be involved. Using radio codes can lead to misunderstandings, particularly if personnel are not familiar with every code or if codes vary between departments.

The focus on clear and straightforward communication helps ensure that all responders, regardless of their specific background or training, can understand instructions and critical information without ambiguity. Therefore, the statement that radio codes are used for efficient communication under ICS is indeed false.
