Why Does the Military Use a Phonetic Alphabet?
The military relies on the phonetic alphabet to clarify communications. In a military situation, a message that isn't understood correctly can have critical consequences. When an RTO is monitoring a radio transmission in a combat environment, both the quality of the signal and the surrounding noise may make it hard to hear clearly. The phonetic alphabet minimizes the possibility of confusing "C Company" with "G Company" by using the easily distinguishable "Charlie Company" and "Golf Company" instead.
History and Current Military Phonetic Alphabet
Since radio became an important tool of military operations, the US armed forces have used several different phonetic alphabets. That's why World War II movies have characters saying "Able Baker Charlie" while present-day soldiers say "Alpha Bravo Charlie" for the same ABC. Here is a chart of the alphabets used by the U.S. and NATO, along with US Navy signal flags.

Phonetic Numbers
There is a similar military phonetic system for numbers:
| Figure | Pronounced |
|---|---|
| 0 | Zeero |
| 1 | Wun |
| 2 | Too |
| 3 | Tree or Thr-ree |
| 4 | Fower |
| 5 | Fife |
| 6 | Siks |
| 7 | Seven |
| 8 | Ate |
| 9 | Niner |
If a decimal point is included in the number, say: DAY-SEE-MAL. You may be trained to say "FIGURES" before starting a string of numbers.
