When saluting while wearing headgear with a visor how should you position the fingers and thumb of the right hand?

When saluting while wearing headgear with a visor, the fingers and thumb of the right hand should be positioned so that the fingers are extended and joined, with the thumb resting on the visor. The hand should be raised to the forehead, ensuring that the palm is facing forward. This position allows for a proper salute while respecting the headgear's design.
