The article describes a model for calculating external ballistics in the full threedimensional formulation in the approximation of the dynamics of a material point. Mathematical modeling of the grenade hitting the target was carried out by the method of statistical tests under variations of shooting external conditions. We estimated a probability of grenade hitting the frontal projection of the tank in different modes of shooting from grenade launcher system. It is shown that probability of grenade hitting the target increases significantly when using a jet engine with a system of autoregulation of thrust characteristics.
