ST Engineering’s 40mm Day & Night Marker (DNM) Round enhances the warfighter's training effectiveness by allowing clear recognition of the 40mm rounds' impact after firing.
It is a fixed round ammunition consisting of an inert aluminium or steel projectile body fitted with a plastic cap filled with a high visibility luminous orange dye.
The round is designed to ensure safe and effective training and is compatible with all existing grenade launchers. It does not produce unexploded ordnance (UXO) and provides visible colour clouds upon impact and a luminoius dye in the dark. The 40mm DNM round is also capable of providing a non-pyrotechnic tracer effect that marks out the projectile's trajectory. Its impact signature and tracer marking are visible through night vision equipment including Image Intensifiers and Thermal Imagers.
