In Procession
The U.S. flag, when carried in a procession with another or other flags, should be either on the marching right (the flag's own right) or, if there is a line of other flags, in front of the center of that line. Never display the U.S. flag from a float except from a staff, or so suspended that its folds fall free as though staffed.
More Than One Flag
When other flags are flown from the same halyard, the U.S. flag should always be at the peak. When other flags are flown from adjacent staffs, the U.S. flag should be hoisted first and lowered last. No flag may fly above or to the right of the U.S. flag (except flags of other nations).
The U.S. flag should be at the center and at the highest point of the group when a number of flags of States or localities or pennants of societies are grouped and displayed from staffs.
On a Building
When the U.S. flag is displayed from a staff projecting from a building, the union of the flag should be placed at the peak of the staff, unless the flag is at half-staff. When suspended from a rope extending from the building to a pole, the flag should be hoisted out, union first, from the building.
With Flags of Other Nations
When flags of two or more nations are displayed, they are to be flown from separate staffs of the same height. The flags should be approximately equal size. International usage forbids the display of the flag of one nation above that of another in time of peace.
Inside a Building
When displayed from a staff in a church or public auditorium, the flag should hold the position of superior prominence, in advance of the audience, and in the position of honor at the clergyman's or speaker's right as he faces the audience. Any other flag so displayed should be placed on the left of the clergyman or speaker or to the right of the audience.
During the Hoisting Ceremony
During the ceremony of hoisting or lowering the flag or when the flag is passing in parade all persons should face the flag, stand at attention, and salute. A man should remove his hat and hold it with the right hand over the heart. Men without hats and women salute by placing the right hand over the heart. The salute to the flag in the moving column should be rendered at the moment the flag passes.
When Honoring the Fallen
When the U.S. flag is used to cover a casket, it should be so placed that the union is at the head and over the left shoulder. The flag should not be lowered into the grave or allowed to touch the ground. Thirteen Farewells explains the symbolism behind folding the flag after it has been raised from the casket by the bearers.
The flag, when flown at half-staff, should be first hoisted to the peak for a moment and then lowered to the half-staff position. The flag should be again raised to the peak before it is lowered for the day.
When Not on a Staff
When the U.S. flag is displayed other than from a staff, it should be displayed flat, or so suspended that its folds fall free. When displayed over a street, place the union so it faces north or east, depending upon the direction of the street.
When Unveiling a Statue or Monument
The U.S. flag should form a distinctive feature at the ceremony of unveiling a statue or monument but should never be used as the covering for the statue or monument.
On a Wall
When the U.S. flag is displayed with another flag against a wall on crossed staffs, the other flag should be on the U.S. flag's right, and the staff of the U.S. flag should be in front of the staff of the other flag.
If displayed flat against the wall on a speaker's platform, the U.S. flag should be placed above and behind the speaker with the union of the flag in the upper right hand corner as the audience faces the flag.
