A thermite grenade is one of the most destructive grenades used by the United States military and after seeing this video you will understand why. The grenade is normally used to blow up materials as opposed to people.
They can reach temperatures of nearly 4,000 degrees Fahrenheit and are excellent for blowing up bunkers and vehicles, such as this limo.
