Introduction

Radio is our primary means of communication in a fast moving, tactical situation. Attempts at sending messages over the radio without guidelines would quickly degenerate into chaos.

Importance

The Marine Corps has established doctrine delineating exactly who will talk to each other on the radio; this doctrine is a guideline for communications planners. How to talk on the radio has been standardized for the sake of brevity and conciseness. Preparing and writing (referred to as drafting) a message has also been standardized for the sake of brevity and accuracy.
