Abstract:

This document describes the procedures for determining the coincidence window of a tank fire control system. The coincidence window is defined as the limits around exact sightgun alignment within which the gun is permitted to fire omitting the offsets imposed by a ballistic solution. Typically, a combat vehicle implements the coincidence windows based on the current alignment static and in some cases additionally the future alignment dynamic of the sight and gun. Procedures for determining coincidence window performance with and without gunner input against the tanks coincidence window and a standard test window of 0.3 mrad x 0.3 mrad are included.
