> NATO phonetic alphabet is used in all areas where you have to say letters over voice.
Not all. Military definitely favors NATO, but there are other phonetic alphabets in use. In particular, at least in the US, fire/ems personnel (and sometimes also law enforcement) use alternatives. The one that goes Adam, Boy (or Baker), Charlie, David, Edward, Frank, ... is still widely used.
I've also known agencies to use a mix, like Adam, Baker, Charlie, Delta, ... (a law enforcement agency that I dispatched for back in the 1990's used this version).

Law enforcement/EMS often have their own phonetic alphabets and it is not that uncommon to use two at once: one for call signs and second for the actual alphanumeric data (in theory, in practice it gets mixed up, but everybody still understands the meaning)
