Best known for family cars, Hyundai and Kia both make military vehicles and artillery pieces, notably howitzers in use by the Indonesian army for the past decade. We are treating these arms dealers as one company, since Hyundai is the parent company of Kia, while Kia in turn owns majority shares in Hyundai subsidiaries.
