The Thumper TG6 Training Grenade is a non-pyrotechnic, reusable, flashbang-style training grenade developed specifically to provide realistic, live-action, immersive combat experiences. Powered by a CO2 cartridge, the Thumper TG6 Training Grenade can produce a sharp, audible report that is both low enough in volume to allow for the optional use of OPFOR personnel instead of paper targets and loud enough to still create the training stress that is such a vital part of good training.
