TDM is abbrevation for TROMBLONSKA DIMNA MINA which means rifle smoke grenade, and TOM is abbrevation for TROMBLONSKA OSVETLJAVAJUĆA MINA which means rifle illumination grenade. They have the same bottom inertial fuze with the same delay, but the purpose of the mine is different-TDM is filled with HC or Hexachlorethane smoke filler and TOM has the internal cardboard cartridge with magnesium illuminating filler and the cartridge has the parachute.Hi, does anyone tell me if there is a difference between fuzes for TDM and TOM yugoslav rifle grenades, there is a different time delay but is it all?
