It covers gunnery teams, battery organization, muzzle velocity management, firing tables, fire commands, and fire mission processing. It addresses accurate target and firing unit locations, weapon and ammunition information, meteorological information, and computational procedures.
Target analysis is the examination and evaluation of an enemy target situation to determine the most suitable weapon, ammunition, and method required to defeat, neutralize, or otherwise disrupt, delay, or limit the enemy. (paragraph 3-78)
Firing tables and technical gunnery procedures allow the unit to consider specific ammunition information (projectile square weight, fuze type, and propellant temperature); thus, accurate firing data are possible. (paragraph 6-2)
Regardless of the type constructed, two firing charts are maintained in a manual FDC. (paragraph 4-53)
A firing chart is a graphic representation of a portion of the earths surface used for determining distance (or range) and direction (azimuth or deflection). (paragraph 6-14)
