ween members of the military brotherhood. According to regulations,
in all services, the salute is initiated by the junior, and at any
convenient distance that insures recognition, the least being about
six paces. The form of the salute is the same in the Army, Navy and
Air Force, and it is given either from the position of attention or at
a walk. It is not given indoors except when reporting to another
officer in an official capacity. In the Navy, it is customary for the
junior initiating a salute to combine it with "Good morning, Sir," as
a means of reinforcing its meaning as a greeting. Where this is done
in the other two services, it is usually the result of a local
directive expressing the wish of a particular commander. While it is
expected that the junior will initiate such a greeting, there is no
obligation upon him to do so, nor is there any reason that the senior
may not say it first.

The Navy and Air Force require that the junior, when engaged in work
that brings him in reasonably frequent contact with the same seniors
during the course of the working day, salute each senior officer the
first time that he is passed during the day, but not subsequently
unless a change in circumstances requires it. In the Air Force an
enlisted mechanic working on the line would salute the engineering
officer and his assistants the first time he recognized them during
the day. If he passed one of the same officers later in the day, for
example in front of the post exchange, he would salute again. The Army
requires that a salute be given and returned each time the junior
passes the senior, unless circumstances dictate that it be temporarily
suspended by common agreement. The Commanding Officer of a naval
vessel is saluted whenever met.

Salutes are not mandatory on the driver of a vehicle, whether moving
or idling at the curb, for the reason that the operator is presumed to
need both hands for driving. Salutes are not exchanged between moving
vehicles, between moving and halted vehicles, or between persons
walking and persons riding in official cars except when it is obvious
that the passenger is a senior, or when it is required as part of a
ceremony. Official vehicles carrying general officers or flag officers
will be clearly marked outside, and will be saluted. A salute is
exchanged between persons in a parked vehicle and persons walking,
unless the car is a bus or taxi. When two boats pass each other, the
senior officer in
