=72. Special units have no fixed posts except at ceremonies.=

Except at ceremonies, the special units have no fixed places. They
take places as directed; in the absence of directions, they conform as
nearly as practicable to the plates, and in subsequent movements
maintain their relative positions with respect to the flank or end of
the command on which they were originally posted. (23)

=73. General, field and staff officers habitually mounted; formation
of staff; drawing and returning saber.= General, field, and staff
officers are habitually mounted. The staff of any officer forms in
single rank, 3 paces in rear of him, the right of the rank extending 1
pace to the right of a point directly in rear of him. Members of the
staff are arranged in order from right to left as follows: General
staff officers, adjutant, aids, other staff officers, arranged in each
classification in order of rank, the senior on the right. The flag of
the general officer and the orderlies are 3 paces in rear of the
staff, the flag on the right. When necessary to reduce the front of
the staff and orderlies, each line executes =twos right or fours
right=, as explained in the Cavalry Drill Regulations, and follows the
commander.

When not otherwise prescribed, staff officers draw and return saber
with their chief. (24)

=74. Mounted officer turns to left in executing about; when commander
faces about to give commands, staff and others stand fast.= In making
the about, an officer, mounted, habitually turns to the left.

When the commander faces to give commands, the staff, flag, and
orderlies do not change position. (25)

=75. Saluting when making and receiving reports; saluting on meeting.=
When making or receiving official reports, or on meeting out of doors,
all officers will salute.

Military courtesy requires the junior to salute first, but when the
salute is introductory to a report made at a military ceremony or
formation, to the representative of a common superior (as, for
example, to the adjutant, officer of the day, etc.), the officer
making the report, whatever his rank, will salute first; the officer
to whom the report is made will acknowledge by saluting that he has
received and understood the report. (26)
