Flashbangs (also called stun grenades, or noise/flash diversionary devices) are single-use weapons thrown or fired into proximity of the victim, which then emit a deafening sound and flash of light. Police use flashbangs to overwhelm their victims’ senses, rendering them vulnerable to further attack.

Tear gas (also called lachrymatory agent or lachrymator) is a chemical weapon that causes extreme pain in the eyes, skin, nose, mouth and lungs. It can lead to vomiting, skin irritation, blindness and even death.
