Among Soviet drivers who raced Estonia 21 cars there were not only members of the national team competed in top series of the period, such as Peace and Friendship Cup, but a lot of drivers representing Soviet national republics of the USSR and local clubs. They competed in many domestic series – USSR Championship, championships of republics (for instance, Belorussian, Estonian or Ukrainian championships), Baltic championship. One of such domestic event was the USSR Army Championship. Despite the name which may seem strange from today’s perspective, it was very competitive series with dozens of drivers and clubs. The reason was that in the USSR motorsport, as a technical sport, was within the competence of the DOSAAF society – a voluntary society for the assistance of the air force, aviation and navy. That is why professional, highly qualified racers competed in the army championships. Vasily Muravskyi from Belorussia, represented Northern Group of Armed Forces, took part in the Championship of the Armed Forces of the USSR in the mid-1980 both in touring and formula cars. In the 1986 Army Championship at Bikernieki circuit near Riga he finished 6th in his Estonia 21M.
