Among grandnesses characterizing fighting vehicles is the so called mobility whose propriety have the essential influence on the dynamic of the vehicle in the field and the active protection against paralyzing chemicals. One of factors having the influence on the motility is the kind and the type of the driving system. Nowadays, the overwhelming majority of tracked fighting vehicles (tanks and infantry fighting vehicles)are equipped with drive unit of the hydro-mechanical type. This type of systems significantly increase motion and mobility proprieties of the vehicle. In the basic tank is implemented a drive unit of the mechanical type. One made an attempt modernizations and the replacement of him with the hydro-mechanical system. As supplementary was accepted hydro-mechanical drive unit whose the construction is modeled on the system HSWL for the heavy vehicle. One skipped the range of adaptive works of the system inside the vehicle. The main attention was concentrated on the influence of the modernization on his traction proprieties. One worked out the original numeric program to determine the traction characteristic of tracked fighting vehicles and special vehicles named DYNH. Data for the analysis one prepared and one worked out using the accessible technical documentation and the expert knowledge of the investigative team. On the work one included some results of numerical calculations of traction proprieties of the tracked fighting vehicle equipped with hydro mechanical drive unit of the type arranged in rows, first class. Results were presented in the form of charts of dynamic and turn characteristics.
