Whenever the National Anthem is played at any place when persons belonging to the military services are present, all officers and enlisted men not in formation shall stand at attention facing toward the music (except at retreat, when they shall face toward the flag). If in uniform, covered, they shall salute at the first note of the anthem, retaining the position of salute until the last note of the anthem. If not in uniform and covered, they shall uncover at the first note of the anthem, holding the headdress opposite the left shoulder and so remain until its close, except that in inclement weather the headdress may be held slightly raised. The same rules apply when “To the Color” or “To the Standard” is sounded as when the National Anthem is played. When played by an Army band, the National Anthem shall be played through without repetition of any part not required to be repeated to make it complete. The same marks of respect prescribed for observance during the playing of the National Anthem of the United States shall be shown toward the National Anthem of any other country when played upon official occasions. The U. S. Navy Regulations prescribe the same honors whenever the National Anthem is played on board a vessel of the Navy, at a Naval Station or at any place where persons belonging to the naval service are present. Civilians wishing to pay the proper honor to the National Anthem should stand at attention whenever present at any place where the National Anthem is played and if covered they should remove the headdress and hold it opposite the left shoulder while standing at attention during the playing of the music. When the President of the United States visits a Fort or Station of the United States Army he is received with the command formed in line under arms, the national colors and regimental standards being carried by the troops, officers and men saluting with the “Present arms,” the band playing the National Anthem followed by four ruffles of the drums and four flourishes of the bugles. An ex-President and Vice President of the United States are received with the same honors except that the band plays a march instead of the National Anthem. The President of a foreign republic or the sovereign or a member of the royal family of a foreign country is received with the same honors as the President of the United States except that the National Anthem of his country will be played by the band. Members of the President’s Cabinet, the Chief Justice, the President pro tempore of the Senate, the Speaker of the House of Representatives, American and foreign Ambassadors and Governors (within their respective states or territories) are received with the same honors as the Vice President except that the number of ruffles and flourishes is three.
