DOK-ING d.o.o. (Rheinmetall Unmanned Vehicles)

DOK-ING d.o.o. of Zagreb was founded in 1991 by Vjekoslav Majetić and builds the MV-4 and MV-10 remote-controlled demining systems as well as special vehicles; since 1 July 2026 Germany's Rheinmetall AG holds the majority and the company also trades as Rheinmetall Unmanned Vehicles.
