nting_.

In a mixed command, _boots and saddles_ is the signal to mounted
troops that their formation is to be mounted; for mounted guard
mounting or mounted drill, it immediately follows the signal _guard
mounting_ or _drill_.

When full dress or overcoats are to be worn, the _full dress_ or
_overcoat_ call immediately follows _first call_, _guard mounting_, or
_boots and saddles_.

_Formation Calls._

805. _Assembly:_ The signal for companies or details to fall in.

_Adjutant's call:_ The signal for companies to form battalion; also
for the guard details to form for guard mounting on the camp or
garrison parade ground; it follows the _assembly_ at such interval as
may be prescribed by the commanding officer.

It is also used as a signal for the battalions to form regiment,
following the first _adjutant's call_ at such interval as the
commanding officer may prescribe.

_To the color:_ Is sounded when the color salutes.

_Alarm Calls._

806. _Fire call:_ The signal for the men to fall in, without arms, to
extinguish fire.

_To arms:_ The signal for the men to fall in, under arms, on their
company parade grounds as quickly as possible.

_To horse:_ The signal for mounted men to proceed under arms to their
horses, saddle, mount and assemble at a designated place as quickly as
possible. In extended order this signal is used to remount troops.

_Service Calls._

807. _Tattoo_, _taps_, _mess_, _sick_, _church_, _recall_, _issue_,
_officers'_, _captains'_, _first sergeants'_, _fatigue_, _school_, and
_the general_.

_The general_ is the signal for striking tents and loading wagons
preparatory to marching.

_Reveille_ precedes the _assembly_ for roll call; _retreat_ follows
the _assembly_, the interval between being only that required for
formation and roll call, except when there is parade.

_Taps_ is the signal for extinguishing lights; it is usually preceded
by _call to quarters_ by such interval as prescribed by Army
Regulations.

_Assembly_, _reveille_, _retreat_, _adjutant's call_, _to the color_,
the _flourishes_, _ruffles_, and the _marches_ are sounded by all the
field music united; the other calls, as a rule, are sounded by the
musician of the guard or orderly musician; he may also sound the
_assembly_ when the musicians are not united.

The morning gun is fired at the first note of reveille, or, if marches
be played before _reveille_, it is fired at the commencement of the
first march
