A salute is a gesture of respect or greeting, often used in military and formal contexts. It typically involves raising the right hand to the forehead or brow, and it is a way for individuals to acknowledge each other’s presence or rank. Salutes can also be performed with a nod or a bow, depending on cultural customs. In the military, salutes are a sign of respect between service members and are often exchanged during ceremonies or when addressing superiors. The act of saluting is governed by specific protocols, which can vary among different branches, such as the Army, Navy, or Air Force.
