Check out this insane video to see what happens when a RPG gunner fires at a tank but misses their mark.
The gunner fires at the Syrian tank but just barely misses their mark. The RPG goes right over the top of the tank. Unfortunately for the gunner, that miss cost the person their life.
The tank quickly gets into position and fires right back at the RPG gunner.
Even if the RPG had directly hit the tank with the RPG, it most likely wouldn’t have caused serious damage considering that most of the armor on a main battle tank is located on the front.
