What mechanism do the California Rangers use for crisis communication during operations?

The California Rangers utilize radio communications and mobile devices for crisis communication during operations due to their efficiency and immediate accessibility in emergency situations. Radio communications allow for real-time, direct contact among team members, which is crucial during rapidly evolving crisis scenarios where timely decisions and updates are vital. The use of mobile devices further enhances communication capabilities, ensuring that rangers can share information quickly, even when on the move or in areas where traditional communications might be less reliable. This method ensures that all team members remain informed and coordinated, which is essential for effective response and management during crises.
