A salute is a gesture of respect or greeting, often performed by raising the hand to the forehead or brow. It is commonly associated with military personnel, where it signifies acknowledgment of authority or rank. The gesture can vary in formality and style across different cultures and organizations. In addition to military contexts, salutes are used in various settings, such as during ceremonies or when greeting dignitaries. The hand salute is one of the most recognized forms, but other types, like the Nazi salute or the Roman salute, have historical significance and implications that vary widely.
