When it is displayed from the same flagpole with another flag - of a
state, community, society or Scout unit - the flag of the United States
must always be at the top except that the church pennant may be flown
above the flag during church services for Navy personnel when conducted
by a Naval chaplain on a ship at sea.
When the flag is displayed over a street, it should be hung
vertically, with the union to the north or east. If the flag is
suspended over a sidewalk, the flag's union should be farthest from the
building.
When flown with flags of states, communities, or societies on
separate flag poles which are of the same height and in a straight line,
the flag of the United States is always placed in the position of honor
- to its own right. ..The other flags may be smaller but none may be
larger. ..No other flag ever should be placed above it. ..The flag of
the United States is always the first flag raised and the last to be
lowered.
When flown with the national banner of other countries, each flag
must be displayed from a separate pole of the same height. Each flag
should be the same size. They should be raised and lowered
simultaneously. The flag of one nation may not be displayed above that
of another nation.
