The article compares the tactical and technical characteristics, combat capabilities of mobile mortar systems of world‟s leading armies with the domestic development of a mobile mortar complex. The domestic defense-industrial complex in cooperation with foreign representatives have developed a new model of mobile mortar complex Bars- 8MMK in which modern technologies for combat use, complex fire for effect based on the integration of intelligence have been implemented. The mortar system is mounted on the chassis of a specialized armored vehicle Bars-8 with a mobile mortar system "ALAKRAN UKR-MMS"; on-board electronic computer provides control of the mortar system in an automated mode - from receiving a command via code calling to automatic guidance of the mortar horizontally and vertically, resumption of guidance after each shot, the issuance of commands and prompts for indicators to mortar crew members, automatic control of guidance. There is a system of automatic alignment and orientation with the accuracy of determining the coordinates of the height of its own position not more than 1-3 m, and the accuracy of determining the direction angle of the longitudinal axis of the vehicle not more than 0-03. GPS system automatically and continuously determines the current rectangular coordinates, the height of the station point and the direction angle of the vehicle axis both in motion and in a stable position, as well as outputs to external devices measured values of orientation and exact time navigation parameters. There is also meteorological system that constantly records data on weather conditions in real time and transmits them to automated fire-control system for the subsequent calculation of firing data. Integrally, the system meets modern operational and strategic requirements. It is also capable of operating under high sustainable conditions, technological in production and repair; provides resistance to the impacts of existing and prospective advanced weapons systems, including those based on new physical principles.

The influence of initial random variations of ballistic factors, such as mass, initial projectile velocity and throwing angle, on the scattering of projectiles by the Monte Carlo method is studied. The study used a computer external ballistic model of the projectile flight of a 30-mm gun, based on a system of differential equations. A parabolic spline is used to interpolate the air drag law of 1943. For each of the selected ballistic indicators (projectile mass, initial velocity of the projectile, and throwing angle), 1000 normally distributed random values were generated, and hit points were calculated, from which the standard deviation was calculated. Several series of computational experiments were performed to study the influence of each factor separately, the pairwise influence of factors and the combined influence of three factors. In the case of the combined effect on the scattering of all three studied factors, the greatest influence is the magnitude of the variation of the initial velocity of the projectile. Software and techniques can be used by munitions developers to improve their combat capabilities and performance ammunition. When firing a firearm, the phenomenon of scattering occurs due to the variety of factors that change randomly from shot to shot. Scattering characteristics are determined by statistical processing of firing data in the range. Projectile scattering is closely linked to the effectiveness of hitting targets, and therefore the study of scattering is given much attention by researchers. For practical application, scattering estimates obtained by statistical analysis of experimentally obtained data are usually used.
