The NATO Phonetic Alphabet (officially the International Radiotelephony Spelling Alphabet) assigns 26 code words (Alfa, Bravo, Charlie...) to the letters of the English alphabet to prevent miscommunication over radio and phone.
The ICAO international spelling uses 'Alfa' and 'Juliett' so that non-English speakers worldwide pronounce the words correctly without phonetic ambiguity.
