The town I grew up in had a huge water tank at ground level. One day I was at a red light and a car comes screaming around the curve, jumps the curb, crashes through the fence and rams the tank. He hit a support strut and besides a good dent didn’t do much damage. I was watching and wondering how much fun surfing in the car would be.
Back on topic: good to know that bullets don’t damage the tanks and I wonder if it would be different if he’d used tracers. (I know very little about tracers so my ignorance may be on full display.)
Tracers are just bullets with a little phosphorous on them that glows when they are fired, so the enemy can see where they are coming from, in order to even things up. Phosphorous is what makes matches light.
When Japanese WW-2 aircraft (without self sealing tanks) were hit with tracers they burned, well like a leaking fuel tank with a match applied.
