To ride a tank or BMP is possible on military bases. In Ukraine currently there are a couple of such bases which can accept tourist for such attraction as shooting and military vehicles driving. Usually it can be organized as a group tour for at least 10 people. However, it is possible to make this shooting tour individual; as a result, the price for the tour will be more expensive if to count per person.
Tank driving does not have any health requirements; consequently, there is no need for any special permission. And all age categories of people can participate in this attraction, except of kids.
