Drill and Ceremony and Uniform Wear
Drill
TC 3-21.5 is the authority. Most commands have two elements - preparatory and execution - unless they are combined commands such as At ease, Rest, or Fall in. Quick time is a 30-inch step at 120 steps per minute; double time is a 30-inch step at 180; the half step is 15 inches; mark time is executed in place. On To the rear, MARCH the Soldier pivots 180 degrees on the balls of both feet. Know who commands a formation, who is in the chain of concern, and how element leaders report.
The salute
Raise the right hand with the upper arm horizontal, forearm at 45 degrees, fingers and thumb extended and joined, and the tip of the index finger touching the edge of headgear near the right eye. Render it about six paces from the person or Colors and hold it until about six paces past. Indoors, salute only when reporting to an officer or when under arms; outdoors, salute when passing the Colors or an officer.
Uniform
The governing directives are AR 670-1 and DA PAM 670-1. Traps: mixing uniform items with civilian clothing, hands in pockets, headgear worn indoors except when under arms, misplacement of rank, name tapes, and patches, and grooming standards applied unevenly. Wear and appearance standards apply on and off duty and on and off post.
Rule of thumb
When unsure of a uniform detail, go to DA PAM 670-1 rather than copying the Soldier next to you - the wrong example has usually already been copied once.
