Semaphore Flag Signaling - Maritime Communication Guide #36625 (License: Personal Use)

This diagram illustrates the classic semaphore signaling system used by navies and maritime services to communicate over distances without radio. Each flag is held in specific positions representing letters (A-Z) or numbers (0-9), with the left arm indicating the first character and the right arm the second. The red-and-yellow bicolored flags improve visibility against sea and sky backgrounds.
