Artillery Operations ____________________________________________________________________________________________ G-7
basic load—The quantity of supplies required to
be on hand within, and which can be moved by, a
unit or formation. It is expressed according to the
wartime organization of the unit or formation and
maintained at the prescribed levels. (JP 1-02)
basic load of ammunition—The amount of
ammunition a unit is authorized to maintain to
initiate combat and sustain itself until resupplied.
battery center—A point on the ground, the coordinates
of which are used as a reference indicating
the location of the battery in the production of
firing data. Also called chart location of the battery.
(JP 1-02)
battery computer system—An automated data
processing system located in the firing battery.
Consists of three major components: lightweight
computer unit, power distribution unit, and 1 to 12
gun display units. Used to compute accurate firing
data and as a digital communications interface.
battery operations center—A facility established
to serve as an alternate fire direction center
and as the battery command post.
blood agent—A chemical compound, including
the cyanide group, that affects bodily functions
by preventing the normal utilization of oxygen by
body tissues. (JP 1-02)
boresighting—The process by which the optical
axes of the weapon sights are aligned parallel to
the axis of the cannon tube. The primary methods
of boresighting are the distant aiming point,
the testing target, or standard angle. Boresight is
verified with the M140/M139 alignment device.
caliber—1. The diameter of the bore of a
weapon; obtained in rifled weapons by measuring
between opposite lands. 2. Diameter of a projectile.
3. Unit of measure used to express the length
of the bore of a weapon. The number of calibers
is determined by dividing the length of the bore
of the weapon (from breech face of the tube to
the muzzle) by the diameter of its bore.
call for fire—A request for fire containing data
necessary for obtaining the required fire on a target.
(JP 1-02)
call-for-fire zone—An area in enemy territory
that the maneuver commander considers
extremely important to neutralize fires from by

to justify firing upon it without adjustment or
observation. (JP 1-02)
cease fire—A command given to air defense
artillery units to refrain from firing on, but to
continue to track, an airborne object Missiles
already in flight will be permitted to continue to
intercept. (JP 1-02)
cease loading—In artillery and naval gunfire
support, the command used during firing of two
or more rounds to indicate the suspension of
inserting rounds into the weapon. (JP 1-02)
centers of gravity—Those characteristics, capabilities,
or localities from which a military force
derives its freedom of action, physical strength,
or will to fight. (JP 1-02)
centigray—A unit of absorbed dose of radiation
(one centigray equals one rad). The term centigray
(1/100 of a gray) (one gray equals 100 rads)
has replaced the term rad and is the equivalent of
one rad. Also called a cGy.
