  (projectile square weight, fuze type, and propellant temperature); thus, accurate firing data are
  possible.
  * Accurate Meteorological Information. The effects of weather on the projectile in flight must be
  considered, and firing data must compensate for those effects. Firing tables and technical gunnery
  procedures allow the unit to consider specific weather information (air temperature, air
  density/pressure, wind direction, and wind speed) in determining accurate firing data.
  * Accurate Computational Procedures. The computation of firing data must be accurate. Manual
  and automated techniques are designed to achieve accurate and timely delivery of fire. The balance
  between accuracy, speed, and the other requirements discussed in this chapter should be included
  in the computational procedures.
  Note. Nonstandard Conditions. If the five requirements for accurate predicted fire cannot be met,
  the FDC needs to take steps to improve firing data. For more information see TC 3-09.81.
  SURVEY
  4-68. FA survey is critical to the first two requirements for accurate predicted fire. FA survey must provide
  indirect fire assets and target locating assets with a common grid. The common grid refers to all firing and
  target-locating elements within a unified command located and oriented to prescribed accuracies with respect
  to a single three-dimensional datum (ATP 3-09.02). Common survey allows the supported commander to
  employ FS resources with a guarantee of accurate and timely FS. Common control is the horizontal and
  vertical map or chart location of points in the target and position area, tied in with the horizontal and vertical
  control in use by two or more units (ATP 3-09.02). Survey planning within the force is based on the following
  tactical considerations:
  * The commander's target adjustment policy (that is, if the element of surprise is an important aspect
  of his tactical plan).
  * The requirement for transfer of adjusted target locations to higher and lower echelons.
  * The required attack of HPTs onto which fire cannot be adjusted (or if surprise is a factor).
  * The planned positioning of indirect fire units during each phase of the operation.
  * The planned tasking of TA sensors and the processing of targets to an attack system.
  4-69. The supported HQ establishes survey timelines and accuracy requirements in the initial planning stages
  of an operation based on the commander's guidance. The supported commander gives the FA BN commander
  targeting priorities and the effects required on HPTs. This information translates into survey requirements
  for the TA sensors and the designated attack systems, which must be on a common grid by the time required.
  The effects on the target and inherent system inaccuracies determine the survey accuracy requirement (hasty,
  fourth-order, or fifth-order survey).
  4-70. There is no longer a military occupational specialty dedicated solely to survey. This creates a need to
  train non-survey soldiers on how to operate the survey equipment. The commander designates the personnel
  to train and form the survey team. The survey team provides survey for the unit. The survey equipment is
  assigned to the FA BN. For more information on survey see ATP 3-09.02.
  PROVIDE PROACTIVE AND RESPONSIVE FIRES THAT CREATE
  DESIRED EFFECTS
  4-71. Effective gunnery, TA, weapons, munitions, C2 are essential for proactive and responsive FA fires to
  supported forces. Procedures must be streamlined to minimize the time between the proactive acquisition of
  a target, the call for fire, and the responsive delivery of fires. A call for fire is a standardized request for
  fire containing data necessary for obtaining the required fire on a target. Unnecessary delay can result
  in a failure to have desired effects on the target. Responsiveness can be achieved by:
  * Training especially digital sustainment training.
  * Streamlining the call for fire through use of digital systems.
  * Planning FS requirements in advance.
