"Let me talk to you about how to salute in the military. It's very exacting, so let me take you through it step by step. The key is, learn how to do it in front of a mirror so by the time you get to basic training you'll be a pro. Here's what you gotta do.
The command to salute is present arms.' The hand salute may be executed while marching, although most of the time you will execute a salute at the position of attention. When wearing headgear with a visor, with or without glasses, on the command of execution which is arms,' raise the right hand sharply, fingers and thumbs extended and joined, palm facing down, and place the tip of the right forefinger on the rim of the visor slightly to the right of the eye. The outer edge of the hand is barely slanted downward. You will know the angle of your hand is correct when neither the back of the hand nor the palm is clearly visible from the front. The hand and wrist are straight, the elbow inclined slightly forward, and the upper arm should be horizontal.
When wearing headgear without a visor and not wearing glasses, execute the hand salute in the same manner as I just described except touch the tip of the right forefinger to the forehead near and slightly to the right of the right eyebrow.
When wearing headgear without a visor and wearing glasses, execute the hand salute in the same manner I just described except touch the tip of the right forefinger to that point on the glasses where the temple piece of the frame meets the right edge of the right brow.
The command for a recruit to release the salute back to the position of attention is order arms. On the command of execution arms,' return the hand sharply to the side resuming the position of attention.
