orienting station—A point established on the
ground which has directional control. The aiming
circle is set up over this point to lay the
pieces by the orienting angle method.
overlay—A printing or drawing on a transparent or
semi-transparent medium at the same scale as a
map, chart, etc., to show details not appearing or
requiring special emphasis on the original. (JP 1-02)
parallel sheaf—In artillery and naval gunfire
support, a sheaf in which the planes (lines) of fire
of all pieces are parallel. See also converged
sheaf; open sheaf; special sheaf. (JP 1-02)
planned target—In artillery and naval gunfire support,
a target on which fire is prearranged. (JP 1-02)
point target—1. A target of such small dimension
that it requires the accurate placement of ordnance
in order to neutralize or destroy it. 2. nuclear—A
target in which the ratio of radius of damage to target
radius is equal to or greater than five.
position area—An area that is occupied, or to be
occupied, by an artillery unit with its elements
disposed to provide artillery support. Position
areas do not constitute a rigid restrictive area for
the artillery unit. They should be considered only
as guides to be followed as closely as the mission,
terrain, and tactical situation permit.
prearranged fire—Fire that is formally planned
and executed against targets or target areas of
known location. Such fire is usually planned well
in advance and is executed at a predetermined
time or during a predetermined period of time.
See also fire; on-call. (JP 1-02)
precision fire—Fire used for registration and for
attack and destruction of point targets.
predicted fire—Fire that is delivered without
adjustment. (JP 1-02)
primary position—The position from which a
battery intends to perform its assigned mission.
priority of fire—Guidance to a fire support planner
to organize and employ fire support means in
accordance with the relative importance of the
maneuver unit’s missions.
priority target—A target that firing units lay on
while not engaged in a fire mission. It is designated
as critical by a maneuver commander on
the basis of type, location, or time sensitivity.
Generally, one battery will be laid on each priority
target (as with a final protective fire).
projectile—An object projected by an applied
exterior force and continuing in motion by virtue
of its own inertia, as a bullet, shell, or grenade.
Also applied to rockets and to guided missiles.
(JP 1-02)
quadrant elevation—The angle between the
horizontal plane and the axis of the bore when the
weapon is laid. (DOD only) It is the algebraic
sum of the elevation, angle of site, and complementary
angle of site. (JP 1-02)
radar—A radio detection device that provides
information on range, azimuth and/or elevation
of objects.
radar fire—Gunfire aimed at a target which is
tracked by radar. See also fire. (JP 1-02)
radar report—A report used by the artillery to
control and coordinate the use of the radars of the
counterbattery radar platoon. The report is used
by the counterbattery radar platoon and the controlling
artillery unit.
radiation dose—The total amount of ionizing
radiation absorbed by material or tissues,
expressed in centigrays. (DOD only) The term
radiation dose is often used in the sense of the
exposure dose expressed in roentgens, which is a
measure of the total amount of ionization that the
quantity of radiation could produce in air. This
could be distinguished from the absorbed dose,
also given in rads, which represents the energy
absorbed from the radiation per gram of specified
body tissue. Further, the biological dose, in
rems, is a measure of the biological effectiveness
of the radiation exposure. (JP 1-02)
