In the phonetic alphabet, which letter corresponds to 'Sierra'?

In the phonetic alphabet, 'Sierra' corresponds to the letter S. The phonetic alphabet, also known as the NATO alphabet or International Radiotelephony Spelling Alphabet, is used to ensure clarity and avoid misunderstandings when communicating letters over radio or telephone, particularly in environments with high potential for interference or low visibility.

Each letter of the alphabet is assigned a specific word to represent it; for example, A is Alpha, B is Bravo, C is Charlie, and so forth.
