Abstract: Disclosed is an environmentally-friendly training hand grenade and a method of manufacturing the same. The training hand grenade is advantageous in that it is not necessary to recover fragments, generated by the explosion of the training hand grenade after use, because a bomb body of the training hand grenade is made of naturally degradable mineral matters, such as barite, tungsten, silica, and yellow earth, thereby many soldiers may be trained for a relatively short time using the training hand grenade. Furthermore, the training hand grenade is made of environmentally-friendly materials, and thus, its use is conducted without causing pollution. In addition, the training hand grenade is made of the mineral matters, thereby ensuring high explosiveness and explosive sound effect when the training hand grenade is exploded, and preventing soldiers from being injured by the fragments in use.
