What is the proper process for reporting to an Officer indoors?

A. When reporting to an officer in his office, the soldier removes his headgear, knocks, and enters when told to do so. He approaches within two steps of the officer’s desk, halts, salutes, and reports, “Sir (Ma’am), Private Jones reports.” The salute is held until the report is completed and the salute has been returned by the officer. b. When the business is completed, the soldier salutes, holds the salute until it has been returned, executes the appropriate facing movement, and departs. c. When reporting indoors under arms, the procedure is the same except that the headgear is not removed and the soldier renders the salute prescribed for the weapon with which he is armed.
