or roger that [roj-er th at ]

What does roger that mean?

Roger that  is a phrase used to affirm or acknowledge a statement or question.

Where does Roger that come from?

roger or rodger

Roger that dates back to US radio communication as early as 1941, based on then-use of the given name Roger in the US military phonetic alphabet  for the word for the letter R.  Here, the Roger stands for the initial R in “(Message) received.”

To indicate a message had been heard and understood—that is, received —a service-person would answer Roger , later expanded to Roger that , with that  referring to the message. In military slang, the phrase  Roger wilco  conveyed the recipient received the message and will comply with its orders, shortened to  wilco .

Roger was brought into the spotlight in part due to public broadcasts of NASA’s Apollo missions in the 1960s. Soon after,  Roger that  entered the popular lexicon as an interjection ( Roger! ), noun ( He gave me the roger ), or verb ( I Roger what you’re asking) to communicate assent or understanding.

Radio code now widely uses the NATO phonetic alphabet, where  Romeo represents R . Contrary to folk etymology, Roger is not a backronym for  Received Order Given , Expect Results .

Examples of Roger that

Who uses roger that.

Though Roger is no longer the official term for R in radiotelephony in the military, law enforcement, aviation, and navigation,  Roger and Roger that  do still enjoy use in military, commercial, and recreational communication to confirm receipt of messages or orders.

Roger that , however, is more commonly used in everyday speech and writing, equivalent to a Yes or OK . For instance, if someone asks over the phone or text-messages “Can you pick up some milk from the store?”, the recipient may reply Roger that for style, familiarity, or for a playfully official or military air.

While Roger that is often used as an affirmation, it frequently appears in questions seeking affirmation: “Do you Roger that?” or “Did you understand my message?”

Rogerthat is also the name of an Australian band.

This is not meant to be a formal definition of Roger that like most terms we define on, but is rather an informal word summary that hopefully touches upon the key aspects of the meaning and usage of Roger that that will help our users expand their word mastery.

"Roger" comes from the phonetic alphabet used by military and aviation personnel during WWII , when the use of two-way radios became a main form of communication and operators need crystal clear ways to spell things out with no room for misinterpretation. You may be familiar with the current NATO version of the phonetic alphabet ( Alpha, Bravo, Charlie , etc.), where the the word for "R" is Romeo, but before that standard was adopted in 1957, the words were a bit different, and the word for "R" was "Roger."

But the use of "Roger" as a confirmation has roots that go back even further, according to a blog post by Jakub Marian . In the Morse code days , when sending long messages could be arduous, a useful shorthand was to respond with single, meaningful letters.

📻 The Best Radios for Emergencies

RegeMoudal Emergency Radio

RegeMoudal Emergency Radio

A battery-powered radio is great to have on hand in the event of a power outage or other emergency, but an even better option is an emergency weather radio. This one uses a solar panel, hand crank, USB cable, and AA batteries to keep its battery charged, along with a bright LED flashlight that can also be used as an SOS beacon. It features a 2000mAh power bank, providing up to 12 hours of light or 4-6 hours of radio time. It can also power up a small tablet or phone.

Sony Portable AM/FM Radio

Son Sony Portable AM/FM Radio

Sony’s ICFP26 portable AM/FM radio may not changed much over the years, but it’s as solid a choice as ever if all you’re looking for something is small, dependable and affordable. The classic design is pared down to just the essentials, with the only extras being a headphone jack and a carrying strap. 

Motorola Talkabout Radio

Motorola Talkabout Radio

A basic two-way radio is another type or radio worth considering whether you regularly spend time outside the reach of other means of communication or not. Something like Motorola’s Talkabout MR350 will let you communicate at distances up to 35 miles and also double as an emergency weather radio, with the ability to pick up NOAA weather channels and receive emergency alerts.Designed for the outdoors, they’re also rugged enough to be tossed around a fair bit, and pack a built-in flashlight so you aren’t left in the dark.

RunningSnail Emergency Radio

RunningSnail Emergency Radio

When the power runs out, you need to make sure your devices are able to maintain a charge, which is why we love this RunningSail radio. It can be charged (and charge your phone!) with a USB cable, by solar charging, or by the hand crank. With all of these options, you know you'll always be powered up. 

Kaito 5-way Emergency Radio

Kaito 5-way Emergency Radio

A radio is great, but good reception is key. This Kaito emergency radio has a telescopic antenna that extends up to 14.5" for high sensitivity reception. Built-in speakers deliver loud and crisp sound, so you're never having to guess what's being said. 

Responding to a message with the letter "R," for example, simply let the sender know their message had been received. When two-way radio came along, the shorthand continued, but with the word "Roger" instead of "R" itself.

Even though Roger has since been replaced with Romeo (and was "Robert" before it was ever Roger), the widespread use of the two-ray radio during the WWII wildly popularized the saying we still use so casually today. Roger that?

Roger That – Meaning, Origin and Usage

Are you looking for a way to confirm receipt of orders from your boss or parents? You could follow their request with the response, “ Roger that ,” to let them know you’re on top of their appeal. This post unpacks the meaning and origin of this expression.

The expression “ Roger that ” is a confirmation statement used to relay your reply to a message received by an authority figure. It’s a way of telling someone that you understand their instructions and plan to execute them.

“ Roger that ” means that you’re communicating with someone through official channels and you receive their message. The phrase is less common in military slang due to replacing “ Roger ” with “ Romeo ” in the phonetic alphabet.

Example Usage

“Roger that, confirmed for landing on runway four. Keep the airspeed low and no flybys this time, Maverick. We don’t need that here.”

“Roger that, honey. I’ll remember to take the trash to the corner before I go to bed, I promise.”

“Roger that, we’ll all rendezvous by the old factory at 15h00. Make sure no one is late, or we’ll start searching for you.”

“Roger, that boss. I’ll have that report ready for you on Monday. Everything is on track, and we’ll be ready to go.”

“Roger that sis, I hear you. We’ll make sure we make the wedding on time, don’t worry about it.”

“I get you, Roger that. We know you need it in the next two hours, and our delivery guy is around the block. It should be with you soon.”

“Roger that. We hear you loud and clear. Avoid the peak at this time of the day. Summitting can be dangerous in this weather.”

“Roger that, we’re ready for rescue. We see the Coast Guard chopper inbound to our location, and we’re ready for pick up.”

roger or rodger

The expression “Roger” originates from US radio communications during the early 1940s. The US military adopted the phonetic alphabet in 1941, with “Roger” representing the letter “R.” In the case of “Roger that,” the “R” in the expression stands for message “received.”

Military service people started adopting the term “Roger that” shortly after introducing the phonetic alphabet, and it was in use well for the end of WWII. If servicepeople received a message or instruction, they would respond with “Roger that” to confirm receipt of the orders.

The military also adopted the saying “Roger Wilco,” meaning the same thing as “Roger that.” The slang term would eventually shorten to “wilco,” to confirm receipt of orders from their command. The expression “Roger that” entered the mainstream language during the 1960s.

The start of the NASA-led “Apollo” space program caught the publics' attention in the international space race. However, modern radio code replaced “Roger” for “Romeo” in the phonetic alphabet. Some people think that “Roger” is an acronym for the phrase “Received Order Given, Expect Results.”

Phrases Similar to Roger That

  • Sure thing.
  • No problem.

Phrases Opposite to Roger That

  • I beg your pardon.

What is the Correct Saying?

  • Roger that.

Ways People May Say Roger That Incorrectly

The phrase has nothing to do with the name “Roger.” It’s a way of confirming that you understand another person’s request or instruction. You can use it with people of any name, and it doesn’t reference what a person named Roger is doing.

Acceptable Ways to Phrase Roger That

You can use “Roger that” as a confirmation statement when someone gives you an instruction or order. It’s a way of boosting their confidence in you by giving them a confident response to what they are asking from you. The phrase suits social and professional use.

Use it at the office when your boss asks you to prepare the financial statements for review. Use it at home when your partner tells you to remember to take the trash out before going to bed. “Roger that” is another way of saying “sure thing” or “no problem.”

Usage of Roger That in Different Contexts

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 saying “I have received your message and understood it.” The term has its roots in the US military phonetic 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 phonetic alphabets, such as the NATO phonetic alphabet, helps to reduce confusion and ensure that letters are correctly understood.

Here are a few examples of how “Roger that” might be used in military 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,” there are several other commonly used phrases in military communication. These include:

This phrase is a crucial part of aviation communication as it helps ensure that everyone involved in the flight is on the same page.

In aviation, clear and concise communication is essential for safety. Pilots and air traffic controllers must communicate effectively to ensure that planes are flying safely and that everyone is aware of what is happening. This is where the phrase “Roger that” comes in. When a pilot or air traffic controller says “Roger that,” it lets the other person know that they have received and understood the message.

For example, if an air traffic controller tells a pilot to change altitude, the pilot would respond by saying “Roger that.” This lets the air traffic controller know that the message has been received and that the pilot will comply with the instructions.

It’s important to note that “Roger that” is not the only phrase used in aviation communication. There are many other phrases and acronyms that are used to communicate specific information. For example, “Mayday” is used to signal an emergency, while “Pan-Pan” is used to signal an urgent message that is not an emergency.

You’ve probably heard the phrase “Roger that” used in movies, TV shows, and other forms of popular culture. It’s a common phrase used in military and aviation communications, so it’s not surprising that it’s made its way into popular culture.

All The Differences

Explained: ‘Copy That’ vs. ‘Roger That’ – Understanding the Difference

Categories Sayings

Explained: ‘Copy That’ vs. ‘Roger That’ – Understanding the Difference

Straight answer: The difference between these two phrases is very little. “Copy that” is used only to acknowledge information, and there’s usually no need to act on that information. Whereas the phrase “roger that” is used to acknowledge some information or instruction, and the receiver will take action upon it.

In Military Lingo, we use both of these terms. In business, saying “Copy that” is like the term “Noted.” It usually means you got the information and will take note of it for next time. However, no one suggests using “Roger that” in business, as it sounds too casual , and it’s not just the right place to use it.

Let’s find out their usage along with their other differences.

Page Contents

What Does “Copy That” Mean?

“ Copy that ” is generally used in speech and text-based communication. It usually translates to “I heard and understood the message”, abbreviated as “copy.”

So, basically, this phrase indicates that the message has been received and understood.

This phrase has been used to reply and to seek confirmation over whether the person has understood the information. The term becomes a question just by simply adding a question mark after it. For example , “Do you copy that?”

Even though it’s not an official term used in military voice procedures, military personnel still widely use it. It used to be exclusive to radio communications, but it got into the vernacular, as many people now use it in everyday speech.

Hollywood movies, shows, and video games use this term, too. I’m pretty sure that’s where you’ve heard this phrase from!

Why Do Soldiers Say Copy That? (Origins)

Although the origins of this phrase are unknown, many believe that Morse code communication established the term . In the older days, all radio transmissions were made in Morse code . It’s a sequence of short and long buzzing noises representing the letters of the alphabet.

Morse code or radio operators couldn’t understand Morse directly. So, they had to listen to transmissions and then note down each letter and number immediately . This technique is known as “copying.”

In short, “Copy that” stood for the complete phrase “I have copied the message onto paper .” This meant that it had been received but not necessarily understood yet.

The radio technology advanced enough to send and receive actual speech. Once voice communications became possible, the word “copy” was used to confirm whether the transmission had been received or not.

Reply to “Copy That”

Even though “copy that” means that one understood the information, it doesn’t say anything regarding compliance.

When one asks if you’ve understood the information, then a better and much simpler response, in this case, is “Wilco.” I heard you, know you, and I’ll comply or take immediate action.

You can keep this in mind for next time when someone asks if you copy or not!

What does the Phrase “Roger That” Mean?

“ R eceived  O rder  G iven,  E xpect  R esults.”

Like “copy that,” this phrase signals that a message has been received and understood. Some also believe that “Roger” is a “yes” reply to confirming a command. It ensures that the recipient agrees with the statement and instructions.

In radio voice procedure, “Roger” basically means “received.” In fact, it’s common in the US military and aviation to reply to one another’s assertions with the phrase “Roger that.” It stands for the words “I understand and have agreed.”

Here’s a list of a few words which mean the same as Roger, and it can be used as a replacement for them:

  • Acknowledged

Origins of the Phrase “Roger That”

The origin of this phrase lies in radio transmissions. It’s considered a slang term and was made famous in NASA’s Apollo Missions radio transmissions.

However, it goes back to some of the first flights ever. Until 1915, pilots highly relied on support from the staff on the ground when flying.

The team also relied on radio transmissions to be able to give clearance to pilots. They sent “R” as a form of confirmation.

As radio technology evolved, there was now two-way communication. The term “roger that” started being used immensely during these times. They began by saying “received” but later shifted to “Roger .” This is because it was a more effortless command and because not all pilots could speak English that well.

This is how the phrase found itself in the aviation industry and the military.

A man informs over a walkie-talkie.

Is Copy That Thee Same as Roger That?

A common question is if “copy that” is the same as “Roger that”? While many people use the phrases interchangeably, “Copy” doesn’t mean the same as “roger”!

“Copy that” is used for communications between two other stations , including information from one’s station. It means that the information has been overheard and received satisfactorily.

Both phrases, “copy that” and “roger that,” are considered jargon used in the military or slang words. You could say that the difference between Roger and Copy is that the former is used to acknowledge an instruction. At the same time, the latter is used to recognize a piece of information that may not require an effort.

While copying means that you understood the message, it doesn’t necessarily mean that you have or will comply with it. Whereas, Roger, in most cases, means that not only did you understand the message, but you’ll also follow its instructions and comply.

In short, “Roger” is more for demands. On the other hand, “Copy that ” is often used as an acknowledgement.

Why is “Roger That” Used Instead of “Yes Sir” in the US Military?

While “Roger that” is common in the military, it’s not the correct response for every situation.

“Roger that” isn’t meant to be used instead of “Yes, sir.” Contrary to popular belief, the meaning and context of using each aren’t generally interchangeable.

“Yes, Sir ” is used to acknowledge or affirm an order or direction. The guidance is usually given by a superior officer, in this case, usually a Commissioned Officer . An enlisted soldier would never say “Yes, Sir” to another soldier.

He would be cautious of using this phrase specifically with a Non-Commissioned Officer (NCO). Moreover, a Commissioned Officer of lesser rank may use this phrase to respond to a superior officer’s order or direction.

On the other hand, “Roger ” conveys immediate understanding and compliance to another soldier or superior. It’s used to respond to soldiers regardless of their rank .

Is Saying “Roger That” Rude?

“Roger that” isn’t rude because it’s still a reply that means they understand what you mean to communicate. It was even derived from the old ways, where the replier would say, “I read you” after hearing the transmission of the other party.

According to another version of its origin, the radio operator shifted from saying the whole phrase “I read you” to its shorter form, “Read yah.” This “read yah” sound was confused and eventually known as “Roger.”

However, many believe that this phrase has no soul and is very robotic. It’s considered nearly an automatic yes and an expression of understanding and obedience.

A group of soldiers ran towards the field.

Copy vs. Roger vs. 10-4

You might have heard of the term 10-4, too. “10-4” is considered an affirmative signal. It simply means “OK.”

The ten codes were created in 1937 by Charles Hopper , the Communications Director of the Illinois State Police. He made them for use in radio communications among cops. It’s now considered CB radio talk!

Here’s a table summarizing the significant difference between Roger, copy, and 10-4:

Other Common Military Phrases

Like “ Roger that” and “ copy that,” there are many other phrases that have been used in radio communication.

Moreover, there’s also a phrase called “Lima Charlie.” This phrase is indicative of the letters “L” and “C” in the NATO alphabet . When used together in military parlance, they stand for “Loud and Clear.”

Another jargon or slang often used in the military is “I’m Oscar Mike.” Sounds weird, doesn’t it? It translates to “On the move.” It was specifically chosen to represent the spirit of its founder, who was a paralyzed marine, and the veterans he served.

In contrast, Navy soldiers use “Aye Aye” instead of “Roger.” This implies that roger was exclusively a term used for military radio communication. They just got so common, so we assumed that it’s applicable anywhere.

Here’s a video on other common military expressions that have become a part of everyday life:

Final Thoughts

  • “Copy that” acknowledges info. “Roger that” means understanding and readiness to act.
  • Both phrases from radio communication confirm understanding in different contexts.
  • “Copy that” confirms received info in everyday and military use.
  • “Roger that” signals an affirmative response. It is common in military and aviation.
  • “Roger that” gained popularity with radio tech advancement.
  • “Copy that” acknowledges but does not necessarily imply action. “Roger that” suggests understanding and agreement to act.
  • “Roger that” isn’t a formal military replacement for “Yes, sir.” It’s a casual recognition.
  • These phrases aid concise communication. It aims for clarity and brevity. It reduces misunderstandings.

Roger That: How to Communicate Using Radio Lingo


"Roger That," "Mayday" & More

There are certain radio terms that are likely already familiar to radio and non-radio users alike because of their prevalence in popular culture, from  police radio codes  on TV to  CB radio  lingo in songs and movies.

Here are some of the terms that will most likely ring a bell even if you're brand new to radio communications.

"Roger That" : A quick way to say that you understand what the other person is saying. "Roger" stems from the days of Morse code communications when the letter "R" was used to indicate "received" or "message understood." As radio communications became more popular and the technology evolved, the U.S. military adopted the term "roger" for the same reason. 

"Mayday":  A term that you will hopefully only ever encounter in the movies and not in real life. It essentially means "life-threatening emergency" and is recognized internationally as a universal distress signal. Most often, "mayday" is used to indicate that a vehicle or transport, such as a plane, boat, helicopter, etc., is going down. The term dates back to the early 1920s and is derived from a French word  m'aidez , which means "come help me."

"Over" : Used at the end of a sentence or phrase to indicate that the person is done speaking. 

"Out" : Indicates that the person is signing off. 

"Read/Copy" : Both words are used to ask if the speaker is being heard or understood, for instance, "Do you read me?" or "Do you copy?" Think of it as the digital radio version of "Can you hear me now?"

"Wilco" : Literally means "will comply" and indicates that the speaker is intending to complete the task that's been asked of them.

CB Radio Lingo

­CB radio lingo is still used by truckers today and continues to evolve. Here are some of the most common rated PG examples of CB radio lingo (remember that we said it was colorful).

Advertising:  a marked police car with its lights flashing

Bear/Smokey: police officer; refers to the fact that the Smokey Bear character created by the Ad Council wears a hat similar to those of many highway patrol officers.

Camera: police radar unit

City Kitty: local police officer

County Mounty: county sheriff or deputy

Evel Knievel:  police officer on a motorcycle; named for the motorcycle stuntman.

Big D: Dallas

Derby City: Louisville, Kentucky

Mardi Gras: New Orleans

Mickey Mouse: Orlando, Florida

Windy City: Chicago

Alligator/Gator: large piece of blown-out tire on the road

Go-go Juice: gasoline or diesel fuel

Nap Trap: hotel or rest stop 

Bulldog:  Mack road tractor

Four-wheeler: any vehicle with only 2 axles; anything that isn’t an 18-wheeler/semi truck

Kiddie car: School bus

Pete/Peter Car: Peterbilt truck

Salt Shaker : snow plow

The 10-Codes

10-codes provide a succinct way of communicating via radio that spans users and industries. You're just as likely to hear a 10-code working in the public safety arena as you are in a manufacturing company.

In short, 10-codes (or 10-signals) are numbers that stand in for phrases. Here are some of the most popular 10-codes and what they mean: 

10-1: Bad reception

10-4: "OK" or "Affirmative," similar to "roger"

10-9: "Say again", or "repeat, please"

10-20: Location, as in "What's your 20?"

10-36: Current time, "Can I get a 10-36?"

10-69: "Message received," again, much like "roger"

10-77: Estimated time of arrival, "Alpha 10-77"

Just like "roger" and "mayday," 10-codes date back to the first half of the 1900s. Charles "Charlie" Hopper (District 10), then communications director for the Illinois State Police, is credited with inventing the codes in the 1930s.

At the time, limitations in radio technology meant that there was a brief delay between the time an officer pressed the button to talk and when the transmission of their voice would begin. Hopper understood that adding the "10" before the codes gave the radios time to catch up, ensuring that complete and abbreviated messages got across.  

Truckers also have their own versions of  10 codes , some of which have the same meanings as law enforcement and others all their own. “10-4,” for example, tends to universally mean “I understand.”

Some argue that  ten codes are a thing of the past  because of inconsistencies in what the codes mean in different departments, geographies and industries. To be sure, lack of consistency has had a disastrous impact on communication and coordination across first responders and law enforcement during natural disasters such as Hurricane Katrina.

Officials, particularly those with the Federal Emergency Management Agency (FEMA), have been urging departments to adopt "Plain Talk" during their radio communications instead of lingo. Clear, descriptive language is replacing the codes in federal communications, and while it may take longer to get messages across, advocates of Plain Talk say it's worth the extra time to ensure interoperability and to make sure everyone understands each other.

The subject isn't yet settled, and the 10-codes are still widely used in public safety, as there is even an official guide created by the Association of Public Safety Communications Officials (APCO). 

The Phonetic Alphabet 

Have you ever had trouble determining what letter someone said? After all, many letters sound the same when spoken. It's easy to confuse "M" with "N" or "B" with "D," especially when you're communicating over an electronic device. In order to solve this, people communicating over radio often refer to letters via the  phonetic alphabet , also known as the spelling alphabet, which is a series of words that indicate the letter. 

The  police phonetic alphabet  is common with officers communicating a license plate number, for instance 111-ABC may be communicated as "1-1-1-Alpha-Bravo-Charlie." The  international phonetic alphabet  is used by sectors around the globe, including public safety, education, health care and even manufacturing, and it's also referred to as the military phonetic alphabet.

Here is the complete list of the phonetic alphabet:

Alpha, Bravo, Charlie, Delta, Echo, Foxtrot, Golf, Hotel, India, Juliet, Kilo, Lima, Mike, November, Oscar, Papa, Quebec, Romeo, Sierra, Tango, Uniform, Victor, Whiskey, X-ray, Yankee, Zulu

A Link to Radio's Past

In addition to its utility and convenience, two-way radio lingo also represents an enduring link to the technology's history. Radio has been a key communications tool for public safety and beyond for decades, and the relationship is far from over as more users recognize the benefits of two-way radio over cell phones and the potential that can be reached with the help of two-way radio service providers.

Every time you hear or say "10-4" or "Roger that," remember that you're part of a long tradition of radio communications.
