The term "stun grenade" refers to a non-lethal weapon used by law enforcement or military personnel to temporarily incapacitate or disorient their targets. The device emits a bright flash of light and a loud noise that can cause confusion, disorientation and loss of balance to anyone within its radius. Some synonyms for stun grenade include flashbang grenade, percussion grenade, concussion grenade, sound grenade, and non-lethal grenade. These devices are designed to create an intense sensory overload that can impair an enemy's ability to react, giving tactical advantage to the user. The use of stun grenades is highly regulated and requires specialized training to operate safely and effectively.
