Understanding Radio Operations at the Platoon Level 💬

In this article, we will delve into the topic of radio operations at the platoon level and explore how to effectively communicate on the radio. Clear and concise communication is crucial for mission success, whether you are a cadet at advanced camp or a soldier in the field. By following the guidelines outlined in ATP 6-2-53, Techniques for Tactical Radio Operations, you can ensure that your radio communications are efficient and understood by all.

The Electromagnetic Spectrum 💡

Before we dive into the specifics of radio operations, let's start with a brief overview of the electromagnetic spectrum. This spectrum encompasses all the different types of waves through which data is transmitted, including sound waves, light waves, microwaves, and more. When it comes to military communications, the focus is primarily on FM (Frequency Modulation) operations. FM communication operates in the VHF (Very High Frequency) range of the spectrum. It's important to note that FM communication requires line-of-sight, meaning that the transmitting and receiving antennas must have a direct visual connection for the message to be received. In contrast, HF (High Frequency) communication does not require line-of-sight and can bounce off the atmosphere and the earth's surface, allowing for long-distance communication.

Modes of Communication in FM Operations 📶

In FM operations, there are three primary modes of communication that you will encounter: single channel plain text, single channel ciphertext, and frequency hop. Single channel plain text refers to regular unencrypted radio communication. This mode is not secure and can be easily intercepted by others. Single channel ciphertext, on the other hand, involves encrypting the radio communication using an SKL (Simple Key Loader) device that stores an encryption key. Only radios with the correct encryption key and frequency schedule can decode and receive the message. The third mode, frequency hop, provides both encryption and frequency hopping capabilities. This mode is highly secure and difficult to intercept, as the radio rapidly changes frequencies during transmission.

Call Signs and Their Significance 📞

Call signs play a crucial role in radio communications, as they identify specific individuals or units. In an infantry unit, the call sign "6" is typically reserved for the officer in charge, known as the OIC. This could be a lieutenant or a captain, depending on the unit size. The call sign "7" is usually assigned to the NCO in charge, such as a platoon sergeant or a first sergeant. Additionally, a "9" call sign is often given to a senior NCO, such as the command sergeant major of the unit. It's important to note that in armored units, the call sign "1" may refer to the officer in charge, resulting in occasional confusion. When communicating with command nodes, such as a Tactical Operations Center (TOC), the call sign "MAIN" is used, while "TAC" or "X-RAY" is commonly employed for a forward operating command post (FOCP).

Understanding Numbers in Radio Communications 🔢

In radio communications, there is a specific way to pronounce numbers to avoid confusion. The numbers "1" and "2" are pronounced normally, followed by "TREE" for "3", "THAUER" or "FOWLER" for "4", "FIFE" for "5", and "NINER" for "9". It is essential to use these pronunciations when transmitting numbers to ensure accuracy and clarity. When reading off grids or other numerical information, it is also advisable to state each digit individually. For example, instead of saying "23 45", say "TWO THREE FOUR FIVE". This practice minimizes the risk of miscommunication and ensures that the message is correctly received.

Pro Words and Their Importance 🎙️

Pro words, also known as procedural words, are standardized terms used in radio communications to convey specific meanings and commands. By using these words correctly, you can enhance the efficiency and clarity of your radio exchanges. Some essential pro words to remember include "acknowledge," which means you understand a transmission; "roger," which indicates receipt of a transmission; "wilco," short for "will comply," signifying that you understand an order and will carry it out; "correction," used to rectify an error in a previous message; and "negative," indicating disagreement or a negative response. Avoid using phrases like "good copy" as a substitute for "roger," as it can be considered improper usage.

Proper Usage of "Over" and "Out" 🗣️

The words "over" and "out" have specific meanings in radio communications and should be used correctly to facilitate smooth exchanges. "Over" is used at the end of a transmission when you expect a response from the receiving party. It signals that you have finished speaking and are awaiting a reply. On the other hand, "out" signifies the end of a conversation and that no further response is required. It is important to note that "over" and "out" should not be used together, as it is redundant and unnecessary. Additionally, it is customary for the initiating party to say "out" to signal the conclusion of the exchange, rather than the other way around.

How to Use "Break" Effectively ⚡

The word "break" can be a valuable tool in radio communications, especially when multiple parties are using the same frequency. By using "break," you introduce a pause in the conversation, allowing someone with higher-priority information to interject. This word gives others the opportunity to make time-sensitive announcements without interrupting ongoing discussions. Additionally, you can use "break" as a way to gather your thoughts or regain clarity during a transmission. For example, if you're in the middle of conveying a series of instructions and need a moment to collect your ideas, say "break" and briefly pause before continuing. Using "break" effectively improves overall communication flow and prevents important messages from being overshadowed.

The Difference Between "I Say Again" and "I Repeat" 🔄

There is a distinct difference between the phrases "I say again" and "I repeat" in radio communications. When you say "I say again," you are asking the receiving party to repeat their previous message. This serves as a clarification request when you didn't hear or understand a particular part of the transmission. On the other hand, "I repeat" is a fire command specifically used to instruct artillery units to fire the same target again. It is crucial to use "I say again" when requesting clarification to avoid any accidental repetition of potentially dangerous commands. Use the appropriate phrase to ensure clear and accurate communication.

Disregard Last: When and How to Use It 🚫

During radio communications, situations may arise where previously transmitted information becomes irrelevant or incorrect. In such cases, the phrase "disregard last" should be used. By saying "disregard last," you are instructing the receiving party to ignore the previous transmission and discard any associated information. This is particularly useful when quick adjustments or changes are made, preventing confusion and ensuring that everyone has the most up-to-date information. Instead of offering lengthy explanations, a simple "disregard last" is sufficient to indicate that the message is no longer valid.

"To Follow": What It Means in Radio Communications ➡️

The phrase "to follow" or "more to follow" refers to additional information or reports that will be transmitted at a later time. It serves as a heads-up for the receiving party to expect subsequent messages related to the current conversation. When you hear or say "to follow," you should be prepared to receive and acknowledge the forthcoming information. This phrase is commonly used in situations where there is a need for multiple reports or updates, allowing for better coordination and comprehension of the overall communication flow.

The Purpose of a Relay ➰

In radio communications, a relay is the act of sending a message through an intermediary when direct communication is not possible. This occurs when the transmitting and receiving parties cannot establish a connection due to distance or terrain obstacles. In such cases, a third party acts as the relay, receiving the message and transmitting it to the intended recipient. A relay can be used to extend the range of communication or overcome interference caused by geographical features. By leveraging a relay, vital information can reach its destination, ensuring effective communication even in challenging circumstances.

The Proper Way to Conduct a Radio Check 📡

Conducting a radio check is a vital practice to ensure that your radio is functioning correctly and that your transmissions are being received clearly. When initiating a radio check, use a specific call sign to establish communication with the desired party. For example, if you are Hawk 6 and want to check your radio with Hawk 7, you would say, "Hawk 7, this is Hawk 6, radio check, over." By ending your transmission with "over," you indicate that you expect a response. The receiving party should then acknowledge the radio check and read back the message you sent, completing the exchange with "roger, over" or "roger, out." This process confirms that both radios are receiving and transmitting properly.

Conclusion ✅

Effective radio operations are essential for successful military missions. By understanding the fundamentals of radio communications, including the electromagnetic spectrum, modes of communication, call signs, pro words, and proper usage of "over" and "out," you can improve your ability to transmit and receive messages accurately. Additionally, utilizing radio checks, relays, and the appropriate phrases like "disregard last" and "to follow" enhances overall communication efficiency. Remember to adhere to the guidelines set forth in ATP 6-2-53 for tactical radio operations. By mastering these skills and employing them consistently, you contribute to clearer, more concise, and more successful radio operations in the field.
