Although the training effect is close to actual combat, the effect is good, when a trainee throws a mine, if the response of the trainee and the trainee is not timely enough, or the misjudgment of the misthrowing direction is caused, accidents are caused, and great potential safety hazards exist.
2. The army developed a kind of training grenade, which uses solid rubber to replace solid steel, the body of the grenade is transparent, a flash lamp operated by 9 volt battery is hidden in the grenade, when the grenade is thrown, the timer starts to count, the flash lamp in the grenade flashes to indicate that the grenade explodes, and even the electric shock can be used to indicate which soldier is hit. However, such mines are more suitable for use in exercises than training. Because the grenade has a great difference in appearance with a live ammunition, secondly, in grenade throwing, misthrowing is often caused by a trainer due to psychological tension and other factors, and the training grenade cannot provide tension feeling of live ammunition training, so that the training effect is greatly compromised.
3. In addition, the training grenade consists of paper bullet barrels, fine river sand, bluish iron powder, clay, firework explosive and a firerope and Jila fire device component, and the training grenade is similar to a live bullet in appearance, but has far away explosion effect, lacks due live bullet experience and still has a small difference with live bullet practice in training effect.
