If you’ve ever watched a movie or a TV show set in the military, you’ve probably heard the phrase “roger that” used a few times. But what does it actually mean, and where did it come from? In this article, we’ll explore the origin and meaning of “roger that” and take a look at some of its common uses.

Roger That Meaning
What Does Roger That Mean?
If you’ve ever watched a military movie or listened to a CB radio conversation, you’ve probably heard the phrase “roger that.” But what does it actually mean?
Roger that is used to acknowledge that a message has been received. In everyday English, it commonly means “I received and understood your message.” In formal radio communication, however, roger confirms receipt of the previous transmission but does not necessarily mean “yes” or “I will comply.”
In short, “roger that” is a way of acknowledging that you heard what the other person said. Depending on the context, it can also suggest that you understand the message, but it does not always mean that you agree with it or will carry out an instruction.
According to the FAA Pilot/Controller Glossary, roger means that the speaker has received all of the other person’s last transmission. The glossary also notes that it should not be used to answer a question that requires a yes-or-no response.
While “roger that” may seem like a simple phrase, it is an important part of clear communication. By confirming that a message has been received, speakers can reduce misunderstandings and make sure important information has not been missed.
Origin of Roger That
Believe it or not, the radio use of “roger” dates back to the World War II era. At that time, the U.S. military used the Joint Army/Navy spelling alphabet to communicate clearly over two-way radios. The word “Roger” represented the letter R, which was used as an acknowledgment that a message had been received.
Over time, “roger” became a common way to confirm receipt of a message. The expanded expression “roger that” also became popular in military-style and everyday communication.
The modern NATO spelling alphabet uses “Romeo” rather than “Roger” for the letter R. However, “roger” has remained in radio communication as a standard acknowledgment. Today, it is still used in military and aviation contexts, as well as in other situations where clear and concise communication is essential.
How Is Roger That Used?
“Roger that” can appear in several contexts, but its tone and exact meaning may change depending on the situation.
Roger That in Military Communication
In military communication, the phrase “roger that” is widely used to acknowledge a message or instruction. It is a shorthand way of indicating that the message has been received. The term has its roots in the older U.S. military spelling alphabet, where the name “Roger” was used to represent the letter R.
When communicating over radio, it is important to use clear and concise language to ensure that the message is accurately received. The use of standardized spelling alphabets helps reduce confusion and ensures that letters are correctly understood.
Here are a few examples of how “roger that” might be used in military-style communication:
- “This is Alpha team. We have secured the objective.” “Roger that, Alpha team. Good work.”
- “Requesting permission to engage enemy forces.” “Negative. Hold your position.” “Roger that. Holding position.”
In addition to “roger that,” several other phrases are commonly heard in radio and military-style communication:
- Copy that – Acknowledges that a message has been received and usually understood.
- Affirmative – Means “yes” and is used to give a positive answer.
- Negative – Means “no” and can indicate that a statement is incorrect, permission is denied, or an action cannot be carried out.
- Wilco – Means that the message has been received and understood and that the speaker will comply with it.
Roger That in Aviation
In aviation, the formal term is normally “roger” rather than “roger that.” It is used to acknowledge that the speaker has received all of the previous transmission. However, “roger” does not by itself mean that the speaker is saying yes or promising to comply with an instruction.
Clear and concise communication is essential for aviation safety. Pilots and air traffic controllers must communicate accurately so that important information is not misunderstood. A general acknowledgment may sometimes be enough, but instructions containing an altitude, heading, or runway assignment should be read back with the aircraft identification.
For example:
In this example, simply replying “Roger that” would not repeat the safety-critical numbers. Reading back the heading and altitude allows both the pilot and controller to check that the instruction was heard correctly.
Roger That in Everyday Conversation
While “roger that” is strongly associated with aviation and military communication, it can also be used in everyday conversation to confirm that you have received a message.
For example, if your friend asks you to meet at a certain time and place, you could respond with “Roger that” to show that you understand the plan.
In ordinary conversation, the expression often sounds playful, confident, or deliberately military-like. In a neutral situation, people are more likely to say “Got it,” “Okay,” or “Understood.” If you want to check whether someone received your message, “Do you copy?” or “Got that?” sounds more natural than “Do you roger that?”
Roger That in Popular Culture
You’ve probably heard “roger” or “roger that” used in movies, TV shows, video games, and other forms of popular culture. Because these expressions are closely associated with military and aviation communication, they are often used to make dialogue sound urgent, professional, or action-oriented.
Films such as Top Gun helped make radio expressions such as “roger,” “negative,” and “affirmative” familiar to a wider audience. Similar language also appears in military-themed TV shows and games.
The phrase has also appeared in music and has been used as the name of songs, bands, and other creative projects. These uses have helped “roger that” become recognizable even to people who do not work in the military or aviation.
Examples of Roger That in Conversation
Here are a few examples of using “roger that” in conversation:
These examples are understandable, but “roger that” gives the responses an informal, radio-style tone. In a formal workplace, “Understood” or “I’ll take care of it” may sound more natural.
Roger That vs. Similar Phrases

| Phrase | Basic Meaning | Important Difference |
|---|---|---|
| Roger | I received your last transmission. | It does not necessarily mean “yes” or “I will comply.” |
| Roger that | I received your message. | Common in military-style and everyday speech; less formal than the standard aviation term “roger.” |
| Copy that | I received and usually understood the message. | Often used informally in radio-style communication. |
| Wilco | I received and understood the message and will comply. | Unlike “roger,” it clearly includes the intention to follow the instruction. |

| Got it | I understand. | A natural and informal choice in everyday conversation. |
