How?

Pretty much just dictionary values and compression. The code between “ and » is just a compressed value that will form the string "Alfa Bravo Charlie Delta Echo Foxtrot Golf Hotel India Juliet Kilo Lima Mike November Oscar Papa Quebec Romeo Sierra Tango Uniform Victor Whiskey Xray Yankee Zulu" by looking up all the words (with single space prefixes, except for "Alfa") in Jelly's dictionary (except for " Xray" which is not in the dictionary, so the direct string value " X" and the dictionary entry "ray" are used instead).

The rest of the code does the rest:

“...»ḲØAżj€⁾: Y - Main link: no arguments
“...»           - the string described above (really a list of characters)
     Ḳ          - split at spaces
      ØA        - alphabet yield - ['A','B','C', ...,'X','Y','Z']
        ż       - zip - makes a list of lists [['A'],['A','l','f','a']],[['B'],['B','r','a','v','o']], ...]
         j€     - join each with
           ⁾:   - the string ": "
              Y - join with line feeds
                - implicit print

Try it online!

If I got rid of the spaces, I'd save 25 bytes, but then I'd have to use a regex. The regex itself would cost quite a few bytes, and it would also remove the capital letter of all words, leaving me with the words lfa, ravo etc. I would therefore have to concatenate the new strings with the leading characters. All this costs bytes.

Old explanation:

fprintf('%s: %s\n',      % Print a string with the format "str: str\n"
num2cell(65:90)          % Create a cell array with the numbers 65 - 90, one in each cell
strsplit('Alfa ...       % Split the string on the default delimiter: space
[num2cell();strsplit()]  % Concatenate cell arrays, leaving us with
                         % {'A',    'B'
                         %  'Alfa', 'Bravo'}
[...]{:}                 % Convert the cell array to a comma-delimited vector

Compiled with NASM and tested with QEMU. To boot you need to put a 2 byte boot signature at the end of the bootsector (510 bytes into the file) so I lost 317 bytes filling the compiled code with zeros. This is my first golf so I have to apologize for any gigantic errors.

[org 7c00h]     ;So NASM can change the labels into memory locations correctly.

cld             ;Tells lodsb to look forward in memory

mov bh, 65      ;Moves the ASCII value of A into the BH register
mov si, NATO    ;Moves the first byte of NATO into the si register
call print      ;Call the 'print' subroutine

jmp $            ;Loops forever

print:
    mov ah, 0eh ;Moves the hex value 0E into the AH register. Tells interrupt 10h that we want subfucntion 0E
    lodsb       ;Load a byte of SI into AL and increments a register (DL i think) that tells it the offset to look at

    cmp al, 3   ;Compares the AL register that now has a byte from our string to ASCII value 3 (Enf Of Text)
    je R        ;If AL == 3 then jump to R

    cmp al, 0   ;Comapre AL to ASCII 0 (NULL)
    je newWord  ;If AL == 0 hump to newWord
    int 10h     ;Execute interrupt 10h Subfunction 0Eh (stored in AH register) which prints character value in AL
    jmp print   ;Jump to print

newWord:
    mov al, 10  ;Move ASCII 10 (New Line) into AL
    int 10h     ;Print character

    mov al, 13  ;Move ASCII 13 (Carriage Return) into AL
    int 10h     ;Print character

    mov al, bh  ;Move BH (which has our starting letter) into AL
    int 10h     ;Print Character

    mov al, 58  ;Move ASCII 58 (:) into AL
    int 10h     ;Print Character

    mov al, 32  ;Move ASCII 32 (Space) into AL
    int 10h     ;Print Character

    mov al, bh  ;Move BH into AL

dw 0AA55H   ;Write the bootsignature

Output

This is what the above code outputs. As you can see A: Alfa is missing and that is because the prompt is 25 lines tall...

To prove I printed A: Alfa I replaced 0,"ulu" with 32,"Z: Zulu" so that Zulu is one on the same line as Yankee.

I would appreciate it if someone told me if I would be able to subtract the 317 bytes of zerofill from my code so it would be 195 bytes. Also if this is even valid because the output won't fit on the screen.

Without trailing newline, 180 bytes:

io.write(("AlfaBravoCharlieDeltaEchoFoxtrotGolfHotelIndiaJulietKiloLimaMikeNovemberOscarPapaQuebecRomeoSierraTangoUniformVictorWhiskeyXrayYankeeZulu"):gsub('%u',"\n%1: %1"):sub(2))

Explanation

str = "AlfaBravoCharlieDeltaEchoFoxtrotGolfHotelIndiaJulietKiloLimaMikeNovemberOscarPapaQuebecRomeoSierraTangoUniformVictorWhiskeyXrayYankeeZulu"
str = str:gsub('%u',"\n%1: %1") -- returns "\nA: Alfa...". %u matches uppercase letters, %1 returns matched letter in this case.
str = str:sub(2) -- remove added newline in the beginning
print(str) -- native print command

It uses Lua's string.gsub substitution function to pattern match the uppercase letters. The letters are then replaced with the requested format (plus the letters themselves). Newlines are also added on the same pass.

The sub-function at the end just trims out newline from the beginning and also works nicely to hide the second return value of gsub, which would have been the amount of replacements.

Loops from 0 to 25, each iteration forming $a of the corresponding capital char. Then string-concatenated with : $a (i.e., the colon-space-letter). Then that string is string-concatenated with an string that's formed by indexing into an array created by -splitting the phonetic string on spaces. Each of those 26 strings is left on the pipeline, and an implicit Write-Output happens at program completion, inserting a newline between elements.

Explaination: There is most likely a much better way to do it, but since i'm new I don't know it. I basically compressed the string with Oc" and put that string to be decompressed using Od"

If someone wants to help me save bytes by using something different from line breaks, I'd be happy to learn!

edit: Saved 2 bytes using ` instead of Od"
