What is the best way of communication between vehicles?

The best way of communication between vehicles is through radio communication. Radios allow for immediate and clear communication over distances, which is crucial in military operations where coordination among units is necessary for operational success. Utilizing radios ensures that all vehicles can quickly share important information, such as tactical movements, obstacles, or changes in mission parameters, without the delays associated with visual or hand signals.

While visual signals and hand signals are useful in certain scenarios, they can be limited by distance, visibility conditions, and the potential for misinterpretation. Written notes are impractical for real-time communication, as they require time to write and read, which may not be feasible in rapidly changing situations. Therefore, radio communication is the most efficient and effective method for relaying information promptly and accurately between vehicles in a military context.
