The game models the military career of a Russian volunteer tanker during the 1991-1995 civil war in Yougoslavia. On the Serbian side there were not only separate volunteer participants of the war, but whole subdivisions made up of the ex-USSR citizens, such as the Russian Volunteer Detachment (RDO-1, RDO-2, RDO-3), the 1st, the 2nd and the 3rd Cossack sotnias. Reasoning from the specificities of the conflict we did not model large-scale tank battles. The game missions are based on the real application of tanks to local conflicts.
