firebombing

Throwing an incendiary bomb or Molotov cocktail. Also the explosion, caused a fire.

Shocker (the villain and foe of Spider-Man) somehow survive after the Punisher firebombing bar with villains, among which was the Shocker. Solid guy.

This soldier was shot with APB from sniper rifle. And body armor can't stop the APB.
