Which type of communication consists of radio transmissions between units during emergency operations?

The type of communication that consists of radio transmissions between units during emergency operations is internal communication. This form of communication is crucial in managing emergency responses as it allows different units or personnel on the ground to coordinate effectively. Internal communication ensures that all responding teams are on the same page, sharing vital information about the situation, resources needed, and tactical decisions.

Radio transmissions serve as the backbone of internal communication in emergency operations, facilitating real-time updates and directives. This form of communication is essential for maintaining operational efficiency and safety among the personnel involved in managing the emergency, ensuring that instructions and situational awareness are disseminated quickly and accurately within the team.
