Military Alphabet A–Z — Full Chart, Codes & Pronunciation

Last reviewed on 26 August 2026.

Military Alphabet A–Z Chart

The military alphabet is the NATO/ICAO phonetic alphabet: 26 code words, one per letter, spoken in place of the letter itself so that sound-alike pairs such as B and D, or M and N, cannot be confused over a radio. There is no separate Army, Navy, Air Force or Marine Corps list — every branch and every NATO nation uses the identical table below.

Military alphabet: letter, code word and pronunciation
Letter	Code Word	Pronunciation
A	Alfa	AL-fah
B	Bravo	BRAH-voh
C	Charlie	CHAR-lee
D	Delta	DELL-tah
E	Echo	ECK-oh
F	Foxtrot	FOKS-trot
G	Golf	GOLF
H	Hotel	hoh-TELL
I	India	IN-dee-ah
J	Juliett	JEW-lee-ETT
K	Kilo	KEY-loh
L	Lima	LEE-mah
M	Mike	MIKE
N	November	no-VEM-ber
O	Oscar	OSS-cah
P	Papa	pah-PAH
Q	Quebec	keh-BECK
R	Romeo	ROW-me-oh
S	Sierra	see-AIR-rah
T	Tango	TANG-go
U	Uniform	YOU-nee-form
V	Victor	VIK-tah
W	Whiskey	WISS-key
X	X-ray	ECKS-ray
Y	Yankee	YANG-key
Z	Zulu	ZOO-loo

Military Alphabet Numbers (0–9)

Digits carry their own mandated pronunciations. Three becomes "TREE" and nine becomes "NIN-ER" so they cannot be clipped into "free" or mistaken for the German nein on a joint net; five becomes "FIFE" because the final /v/ is easily lost under noise.

Military pronunciation of the digits 0 to 9
Digit	Pronunciation
0	ZE-RO
1	WUN
2	TOO
3	TREE
4	FOW-ER
5	FIFE
6	SIX
7	SEV-EN
8	AIT
9	NIN-ER

NATO Military Standards

The NATO phonetic alphabet is the foundation of military communications across all 31 NATO member nations. Standardized through STANAG 7085 (Standard Agreement), it ensures clear communication between forces speaking different native languages during joint operations, training exercises, and combat situations.

While the alphabet itself — Alfa through Zulu — remains constant across all branches and nations, its application varies based on tactical requirements, communication security protocols, and operational environments.

STANAG 7085 Requirements

The NATO Standardization Agreement 7085 mandates:

Exclusive use of ICAO/ITU phonetic alphabet (no variations permitted)
Standard number pronunciations (WUN, TOO, TREE, FOW-ER, FIFE, etc.)
Consistent stress patterns across all NATO forces
Integration with tactical brevity codes
Interoperability with civilian aviation standards

Mandatory Contexts

Grid coordinates and map references
Call signs and unit identifiers
Frequency designations
Authentication codes
Serial numbers and equipment IDs
Personnel identification in radio traffic

US Military Branch Usage

Branch-specific phonetic alphabet applications
Branch	Primary Use Cases	Unique Protocols
Army	Grid coordinates, call signs, MEDEVAC requests	9-line MEDEVAC format, fire support coordination
Navy	Ship designations, bearing/range, signal flags	Parallel use with naval signal flags
Air Force	Aircraft call signs, runway designations, waypoints	Integration with ATC procedures
Marines	Amphibious ops, close air support, artillery	Ship-to-shore coordination protocols
Space Force	Satellite IDs, orbital elements, ground stations	Integration with NASA communications
Coast Guard	Vessel identification, SAR operations	Maritime distress procedures

Tactical Brevity Codes

Military communications combine the phonetic alphabet with standardized brevity codes for rapid, secure information exchange:

Common Air Combat Codes

Selected tactical brevity codes used with phonetic alphabet
Code Word	Meaning	Phonetic Usage Example
ANGELS	Altitude in thousands of feet	"Angels Two-Five" = 25,000 feet
BANDIT	Identified enemy aircraft	"Bandit, bearing Three-Two-Zero"
BINGO	Minimum fuel for return	"Bingo fuel in Five Mike"
BOGEY	Unidentified radar contact	"Bogey, Bulls Two-Seven-Zero for Forty"
FOX	Missile launch (1/2/3 = type)	"Fox Two, Fox Two"
WINCHESTER	Out of ordnance	"Eagle One-One is Winchester"

Ground Forces Codes

MIKE: Minutes (e.g., "Five Mike" = 5 minutes)
KLICK: Kilometer (e.g., "Two Klicks north")
OSCAR MIKE: On the Move
LIMA CHARLIE: Loud and Clear
TANGO UNIFORM: Toes Up (deceased/destroyed)
WHISKEY PETE: White Phosphorus

Grid Coordinates and Map References

Military grid reference system (MGRS) requires precise phonetic spelling:

Example MGRS Coordinate:

Written: 18S UJ 23480 06550

Spoken: "Grid: One Eight Sierra, Uniform Juliett, Two Three Four Eight Zero, Zero Six Five Five Zero"

Fire Support Coordination

Artillery and close air support requests use standardized formats with mandatory phonetic spelling:

Observer identification
Warning order
Target location (grid)
Target description
Method of engagement
Method of fire and control

9-Line MEDEVAC Request

Medical evacuation requests demonstrate critical phonetic alphabet usage:

Standard 9-line MEDEVAC format with phonetic requirements
Line	Information	Phonetic Example
1	Location	"Grid: One Eight Sierra, Uniform Juliett..."
2	Radio frequency/call sign	"Four Seven point Five Five, call sign Kilo Six"
3	Number of patients by precedence	"Alpha: Two, Bravo: One" (A=Urgent, B=Priority)
4	Special equipment	"Alpha" (none), "Bravo" (hoist), "Charlie" (extraction)
5	Number by type	"Lima: Three" (L=Litter)
6	Security at pickup	"November" (No enemy), "Echo" (Enemy), "X-ray" (Armed escort)
7	Marking method	"Alpha" (panels), "Bravo" (pyro), "Charlie" (smoke)
8	Patient nationality	"Alpha" (US Military), "Delta" (US Civilian)
9	NBC contamination	"November" (Nuclear), "Bravo" (Biological), "Charlie" (Chemical)

Radio Procedures

Prowords (Procedure Words)

Standard NATO prowords used with phonetic alphabet:

ROGER: Message received and understood
WILCO: Will comply (never used with "Roger")
OVER: Transmission complete, response expected
OUT: Transmission complete, no response expected
SAY AGAIN: Repeat transmission (never "repeat" — artillery term)
BREAK: Separates text from other portions
WAIT ONE: Pause for a few seconds
CORRECTION: Error in transmission, correct version follows

Authentication Procedures

Challenge-response authentication uses phonetic alphabet exclusively:

Station A: "Authenticate: Alpha Tango"

Station B: "I authenticate: Whiskey X-ray"

International NATO Usage

Non-English NATO Forces

All NATO members use the same phonetic alphabet regardless of native language:

German Bundeswehr: Uses NATO alphabet, not German spellings
French Armed Forces: NATO standard despite different French alphabet
Turkish Armed Forces: Full NATO compliance
Polish Armed Forces: Transitioned from Warsaw Pact to NATO standards

Joint Operations

Multinational exercises require strict adherence:

No national variations permitted
English as operational language
Standard pronunciation mandatory
Common brevity codes across forces

Military Training Standards

Basic Training Requirements

Week 1: Phonetic alphabet memorization
Ongoing: Daily use in all communications training
Testing: 100% accuracy required for graduation
Field exercises: Evaluated under stress conditions

Advanced Training

NCO schools: Teaching proper radio discipline
Officer training: Multi-national communication protocols
Special operations: Covert communication methods
Joint terminal attack controllers: Integration with aviation

Equipment and Technology

Radio Systems

SINCGARS: Single Channel Ground and Airborne Radio System
JTRS: Joint Tactical Radio System
SATCOM: Satellite communications
Blue Force Tracker: Digital position reporting

Digital Integration

Modern systems auto-convert text to phonetic:

Tactical chat systems
Automated position reports
Digital fire control systems
UAV control stations

OPSEC Considerations

Operational security with phonetic alphabet:

Never spell classified codewords phonetically over unsecure channels
Use encryption for sensitive grid coordinates
Rotate call signs regularly
Avoid patterns in authentication challenges
Monitor for direction-finding risks with extended transmissions
