Abstract: Determining projectile consumption is one of more important factors for achieving success when conducting indirect fires tasks and depends on the accuracy of preparation of initial elements, mathematical expectation of number of hits and probability of hitting the target. This paper shows the procedure for determining projectile consumption of a 120 mm mortar platoon during indirect engagement of predetermined target in accordance with the predefined number of required direct hits, based on the developed model, and by applying appropriate formulas, coefficients and table values.

Keywords: projectile consumption, probability of hitting the target, mathematical expectation of number of direct hits, indirect fire.
