The Military Alphabet (NATO Phonetic Alphabet): Full A-Z Chart
The military alphabet is the set of 26 code words, Alfa through Zulu, that every NATO force uses to spell letters over the radio so a “B” is never heard as a “D.” Its official name is the NATO phonetic alphabet. It is the same set the International Civil Aviation Organization (ICAO) uses for civil aviation and the International Telecommunication Union (ITU) lists for international radio.
We coach recruits, selection candidates, and operators who learn this language in the same months they build the physical capacity the job demands. That is why our military fitness workout programs treat comms drills, land navigation, and load carriage as parts of one preparation. Below you get the full A-Z chart, a printable version, the numbers, pronunciation for every letter, how it differs from police usage, where it came from, and a daily drill to lock it in.
Key Takeaways:
The military alphabet and the NATO phonetic alphabet are the same thing: 26 code words from Alfa to Zulu.
The Army, Navy, Air Force, Marine Corps, Space Force, and Coast Guard all use the identical set, as do pilots and air traffic controllers worldwide.
The official spellings are Alfa and Juliett, chosen so non-English speakers pronounce them correctly.
Many U.S. police agencies still use the older APCO alphabet (Adam, Boy, Charles), so the two are not interchangeable.
Short daily recall sessions beat rereading the chart, a finding backed by decades of memory research.
The Military Alphabet A-Z (Full Chart)
The military alphabet assigns one code word to each letter: Alfa, Bravo, Charlie, Delta, Echo, Foxtrot, Golf, Hotel, India, Juliett, Kilo, Lima, Mike, November, Oscar, Papa, Quebec, Romeo, Sierra, Tango, Uniform, Victor, Whiskey, X-ray, Yankee, and Zulu. Over the radio, “Smith” becomes Sierra, Mike, India, Tango, Hotel.
That is the whole military spelling alphabet. The chart below lists all 26 military alphabet letters with the pronunciation published by ICAO, with the stressed syllable in capitals.
A: Alfa (Alpha), pronounced AL-fah
B: Bravo, pronounced BRAH-voh
C: Charlie, pronounced CHAR-lee or SHAR-lee
D: Delta, pronounced DELL-tah
E: Echo, pronounced ECK-oh
F: Foxtrot, pronounced FOKS-trot
G: Golf, pronounced GOLF
H: Hotel, pronounced hoh-TELL
I: India, pronounced IN-dee-ah
J: Juliett, pronounced JEW-lee-ETT
K: Kilo, pronounced KEY-loh
L: Lima, pronounced LEE-mah
M: Mike, pronounced MIKE
N: November, pronounced no-VEM-ber
O: Oscar, pronounced OSS-cah
P: Papa, pronounced pah-PAH
Q: Quebec, pronounced keh-BECK
R: Romeo, pronounced ROW-me-oh
S: Sierra, pronounced see-AIR-rah
T: Tango, pronounced TANG-go
U: Uniform, pronounced YOU-nee-form or OO-nee-form
V: Victor, pronounced VIK-tah
W: Whiskey, pronounced WISS-key
X: X-ray, pronounced ECKS-ray
Y: Yankee, pronounced YANG-key
Z: Zulu, pronounced ZOO-loo
Military Alphabet Numbers
Numbers get the same treatment. Radio procedure modifies a few digits so they cannot be confused with each other or with English words. “Nine” becomes “niner” because a bare “nine” can be mistaken for the German “nein,” and “five” becomes “fife” so it stays distinct from “nine.”
0: ZEE-ro
1: WUN
2: TOO
3: TREE
4: FOW-er
5: FIFE
6: SIX
7: SEV-en
8: AIT
9: NIN-er
Numbers are spoken digit by digit. A grid coordinate of 4859 goes out as “fow-er, ait, fife, nin-er,” never “forty-eight fifty-nine.”
Printable Military Alphabet Chart (PDF)
A printable military alphabet chart works best when it sits where you will see it during the day, not in a folder you never open. We built a one-page military phonetic alphabet chart with all 26 letters, the pronunciation guide, and the radio numbers on a single sheet.
Use it three ways:
Tape it inside your locker or next to your desk. Passive exposure builds familiarity before you start testing yourself.
Save it as your phone lock screen for one week. You check your phone dozens of times a day, and each glance is a free rep.
Print a wallet-size copy for the field. Recruits and new radio operators keep one in a cargo pocket until the words come without thinking.
The chart is a starting point. The phonetic alphabet chart military recruits rely on is the one in their head, so treat the printout as training wheels and plan to retire it.
Phonetic Alphabet, Code, or Letter Codes? What the Military Alphabet Is Called
The military phonetic alphabet, the military alphabet code, military code alphabet, military letter codes, and the military alphabet words or names all describe the same 26 code words. The formal names are the NATO phonetic alphabet and the ICAO radiotelephony spelling alphabet. Every other label is a nickname for that one system.
Two of those nicknames are technically inaccurate, and knowing why helps you understand what the system does.
It is not a code. A code hides meaning from people without the key. The military alphabet hides nothing. Anyone with a printed chart can decode “Bravo, Romeo, Alfa, Victor, Oscar” in seconds. Its only job is clarity.
It is not strictly phonetic. Linguists use “phonetic alphabet” for systems like the International Phonetic Alphabet, which represents speech sounds. The NATO set represents written letters. That is why ICAO calls it a spelling alphabet, and why “military spelling alphabet” is the most precise search term of the bunch.
In practice, nobody on a net will correct you for saying “phonetic alphabet.” Use whatever term your unit uses. Just know that all of them point to the chart above.
Each Letter Explained: Alpha, Bravo, Charlie to Zulu
Every code word was chosen for a reason, and several carry meanings well beyond spelling. Here is each letter in the military alphabet, with the context you will hear on the radio and in the barracks.
A to G in the Military Alphabet
A is Alfa. Officially spelled with an “f” because speakers of some languages would not read “ph” as an “f” sound. Most U.S. writing still uses “Alpha.”
B is Bravo. “Bravo Zulu” means “well done,” a phrase that came from the Allied naval signal book.
C is Charlie. “Charlie Mike” means “continue mission.” ICAO accepts the “SHAR-lee” pronunciation for French speakers.
D is Delta. Also used to designate the fourth unit or element in a sequence.
E is Echo. One of the shortest words in the set, kept because nothing else on the chart sounds like it.
F is Foxtrot. Two hard syllables that survive heavy static.
G is Golf. A single syllable that ends on a hard consonant, which keeps it distinct from every other letter.
H to N in the Military Alphabet
H is Hotel. Stress the second syllable: hoh-TELL.
I is India. Three syllables, so it cannot be confused with “Echo.”
J is Juliett. Spelled with a double “t” so French speakers do not treat the final “t” as silent.
K is Kilo. Also shorthand for kilogram and kilometer, so context matters.
L is Lima. Pronounced LEE-mah, like the capital of Peru, not like the bean.
M is Mike. “Oscar Mike” means “on the move.” Mike is also shorthand for minutes (“five mikes”).
N is November. The longest code word on the chart, which makes it nearly impossible to mishear.
O to U in the Military Alphabet
O is Oscar. Paired with Mike for “on the move.”
P is Papa. Stress the second syllable: pah-PAH. This is one of the most searched letters, because “P” and “B” are easily confused on a bad signal.
Q is Quebec. Kept the French pronunciation, keh-BECK.
R is Romeo. The older alphabet used “Roger” here, which is why “Roger” still means “received” on the radio.
S is Sierra. Three syllables, stress on the middle.
T is Tango. “Tango” is also slang for a target or hostile.
U is Uniform. ICAO accepts both “YOU-nee-form” and “OO-nee-form.”
V to Z in the Military Alphabet
V is Victor. One of the few words carried over from the older U.S. alphabet.
W is Whiskey. Stress the first syllable.
X is X-ray. Few English words start with X, so the designers kept the obvious choice.
Y is Yankee. Distinct from “Uniform” despite the similar letters.
Z is Zulu. “Zulu time” is military shorthand for Coordinated Universal Time (UTC), because the Z time zone sits on the prime meridian.
Do the Army, Navy, and Air Force Use the Same Alphabet?
All U.S. military branches use the same phonetic alphabet. The Army, Navy, Air Force, Marine Corps, Space Force, and Coast Guard all use the NATO set, as do allied forces across NATO. The “army alphabet” or “army alphabet code” you see searched is the same 26 words, taught in Army radio doctrine and in joint NATO communication procedures.
Standardization is the point. A Marine forward observer, a Navy ship, and an Air Force pilot may all share one net during a joint operation. If each branch spelled letters differently, a grid coordinate or call sign could be misread at the exact moment accuracy matters most. One shared alphabet removes that failure point.
Most service members first meet the military alphabet at basic training or boot camp, alongside rank structure, drill, and the 24-hour clock. Like the military rank chart, it is shared knowledge every branch expects you to have cold before your first assignment. Recruits who arrive already knowing both have more attention left for everything else boot camp throws at them, including the physical standards. If you are still working out what to train before you ship, our military fitness FAQ answers the questions recruits ask most.
Military vs Police vs Aviation Phonetic Alphabets
The military and aviation alphabets are identical: pilots and air traffic controllers use the same ICAO list that NATO adopted. Police are the exception. Many U.S. law enforcement agencies still use the older APCO alphabet, built on common first names and words, though a growing number have switched to the NATO set.
A: Alfa / Adam
B: Bravo / Boy
C: Charlie / Charles
D: Delta / David
E: Echo / Edward
F: Foxtrot / Frank
G: Golf / George
H: Hotel / Henry
I: India / Ida
J: Juliett / John
K: Kilo / King
L: Lima / Lincoln
M: Mike / Mary
N: November / Nora
O: Oscar / Ocean
P: Papa / Peter
Q: Quebec / Queen
R: Romeo / Robert
S: Sierra / Sam
T: Tango / Tom
U: Uniform / Union
V: Victor / Victor
W: Whiskey / William
X: X-ray / X-ray
Y: Yankee / Young
Z: Zulu / Zebra
Why the split exists: the APCO list was built for American English speakers on domestic radio networks. The NATO list was built and tested for speakers of many languages, which is why it uses words like Quebec and Juliett that read the same across English, French, and Spanish.
What it means for you: if you are a veteran moving into law enforcement, expect to learn a second set or to find your agency already on NATO. Usage varies by department, so check your agency’s radio procedures before your first shift. Some agencies also substitute a few words of their own on top of the APCO base.
Where the Military Alphabet Came From and Why the Military Uses It
The military uses a phonetic alphabet because radio strips speech down to a narrow, noisy signal. Letters like B, D, E, P, T, V, and Z rhyme, and on a weak signal they become indistinguishable. Replacing each letter with a distinct, multi-syllable word means one bad syllable does not destroy the message.
Who Invented the Military Alphabet?
No single person invented the military alphabet. During World War II, U.S. forces used the Joint Army/Navy alphabet (Able, Baker, Charlie, Dog, and so on). It worked well for native English speakers and poorly for everyone else.
After the war, ICAO set out to build an alphabet that worked for pilots and controllers of any nationality. Linguist Jean-Paul Vinay of the Université de Montréal led much of the research, testing candidate words with speakers of English, French, and Spanish. A first version came out in 1951 and drew complaints, so ICAO revised it. The final list took effect in 1956, and NATO adopted it the same year. It has stayed essentially unchanged since then.
Why Phonetic Spelling Matters on Comms
The stakes explain the design. A transposed letter in a call sign sends traffic to the wrong station. A misheard grid reference puts fire or a medevac in the wrong place. Each word on the chart was tested for how well it survives noise and accents, which is why the set reads oddly in places (Alfa, Juliett) and works reliably under pressure.
Some of the old alphabet survives in radio language. “Roger” (the old R) still means “received,” and “Victor” and “X-ray” carried over unchanged.
How to Learn and Memorize the Military Alphabet
To memorize the military alphabet, learn it in four blocks, test yourself instead of rereading, space short sessions across several days, and practice saying it out loud under fatigue. Rereading a chart feels productive and builds little recall. Pulling the answer from memory is what makes it stick.
Split it into four blocks. Learn A to G, then H to N, then O to U, then V to Z. Six or seven words at a time fits easily in working memory.
Test, don’t reread. Cover the code words and recall them from the letter, then reverse it. Research on retrieval practice shows self-testing produces stronger long-term recall than restudying the same material.
Space the sessions. Five minutes a day for a week beats one 35-minute session. Spaced practice consistently outperforms massed practice in memory research.
Spell what you see. License plates, street signs, unit designations, your own name. Every one is a free rep.
Say it out loud at radio cadence. Spelling in your head is not the same skill as transmitting clearly. Speak each word distinctly, with a short pause between them.
Add the numbers last. Once letters are automatic, mix in niner, fife, and tree with grid coordinates and call signs.
Practice it tired. Real transmissions happen after a movement under load, not after a full night of sleep. Run your spelling drill at the end of a ruck or interval session, when your breathing and focus are compromised.
That last point is where the communication skill and the physical one meet. Selection courses and field exercises test your ability to think and transmit clearly while exhausted, and that capacity is trained, not given. If you are choosing a program to build that capacity, the military fitness buying guide walks through how to pick one that matches your job and timeline.
FAQ: Frequently Asked Questions
What is the military alphabet called?
The military alphabet is formally called the NATO phonetic alphabet, and ICAO calls the same list the radiotelephony spelling alphabet. People also search for it as the military phonetic alphabet, military alphabet code, or military letter codes. All of these terms describe the same 26 code words, Alfa through Zulu, used by every U.S. branch and NATO force.
What is B, G, M, N, and P in the military alphabet?
In the military alphabet, B is Bravo, G is Golf, M is Mike, N is November, and P is Papa. Other commonly searched letters: J is Juliett, U is Uniform, and Q is Quebec. Papa is pronounced pah-PAH, with the stress on the second syllable, which helps keep it distinct from Bravo on a weak signal.
Who invented the military alphabet?
No single person invented it. ICAO developed the current alphabet after World War II to replace the English-centric Able/Baker system, with linguist Jean-Paul Vinay of the Université de Montréal leading much of the research. Words were tested with English, French, and Spanish speakers. The final version took effect in 1956, and NATO adopted it that year.
Why does the military use a phonetic alphabet?
The military uses a phonetic alphabet because radio distorts speech, and many letters sound alike on a noisy signal. Replacing each letter with a distinct word prevents errors in call signs, grid coordinates, and names. One misheard letter can send fire, aircraft, or a medevac to the wrong location, so clarity is a safety requirement.
Do all military branches use the same phonetic alphabet?
All U.S. military branches use the same phonetic alphabet. The Army, Navy, Air Force, Marine Corps, Space Force, and Coast Guard use the NATO set, as do allied NATO forces and civil aviation worldwide. A single shared alphabet lets units from different branches and countries communicate on one net without spelling errors.
Do police use the military alphabet?
Some police agencies use the military alphabet, and many U.S. departments still use the older APCO alphabet (Adam, Boy, Charles, David). Usage varies by agency and region, and a growing number have adopted the NATO set for interoperability with other agencies. Check your department’s radio procedures before assuming either one.
The military alphabet is 26 words, and it takes about a week of short daily sessions for most people to get them down. The difference between knowing the chart and owning it is whether you can spell a grid coordinate cleanly when you are breathing hard at the end of a movement. That is a physical skill as much as a mental one.
Learn the chart this week, then build the engine that lets you use it under load. Pick the program that matches your branch and timeline, and start training for the job you are about to do.
