Which letter is represented by 'Oscar' in the phonetic alphabet?

In the phonetic alphabet, 'Oscar' specifically represents the letter O. The phonetic alphabet, often used in military and aviation contexts to communicate letters clearly over radio or telephone, assigns unique words to each letter of the English alphabet to avoid confusion. For instance, 'Alpha' is for A, 'Bravo' for B, and so forth. Each word corresponds to one letter, and in this case, 'Oscar' clearly stands for the letter O. Understanding this system helps ensure precise communication, especially in noisy environments or situations that require clarity, such as identifying aircraft or locations.
