each boat salutes without rising.

Aside from saluting, there are certain other customs that govern
conduct around official vehicles. Since the place of honor is on the
right, the junior not only walks on the left, but rides there as well.
In entering a car, the junior enters first, followed by other members
of the party in inverse order of rank, each seating himself so that
the senior may take position on the right side. In leaving the car,
the senior debarks first. However, if following this general procedure
would necessitate any member of the party climbing over another, or
in any other way cause an awkward situation, the senior may enter
first and alight last.

The same rules govern for boarding and leaving small boats, except
that the junior rides forward and the senior aft.

In boarding aircraft with a single hatch, the pilot enters first,
followed by the copilot and other members of the crew. With the crew
in place, other passengers enter according to rank, the senior first;
he takes the seat of his choice if the aircraft is equipped with
seats. In either transport or tactical aircraft, the senior officers
generally ride as far forward as possible. In leaving the aircraft,
the aircrew who handle deplaning normally leave first, followed by
passengers in order of seniority.

The long association of the Air Force with the Army precludes any
large body of custom and tradition that can be called peculiarly Air
Force in origin or usage. In time undoubtedly a considerable body of
distinctive official and social courtesies will grow, but at present
most of the official and unofficial usages given here for the Army are
understood to be applicable to the Air Force as well, and will be so
treated.

The hand salute is required on all military installations and in
occupied territories, whether on or off duty; in all official greeting
in the line of duty both on and off the base; for ceremonial
occasions; and in honoring the National Anthem, or color, or
distinguished persons.

Since most military posts or bases are guarded on a twenty-four hour
basis, the first official contact will be with the guard on the main
gate. He may be a soldier or airman selected by roster and under the
temporary control of the Officer of the Day, a Military Policeman
wearing an MP brassard and under the command of the Provost Marshal,
or a civilian guard either under the Provost or some other special
staff agency of the Post or Base Comman
