In 1995, Shawn Nelson, a former Army tank commander drove into a National Guard armory and stole an M60A3 tank. He drove the tank out of the armory, and onto residential streets where he began crushing things in his path. He drove the tank onto a highway and was pursued by a number of San Diego Police Department cars.
Eventually, Nelson crashed the tank into a concrete barrier and police embarked on top of the turret where they cut the hatch open with bolt cutters. Nelson began to spin the tank in an attempt to shake the officers off and was shot by police.
He tried starting two other tanks before driving off in the one he stole. National Guard maintenance in shambles.
His fault for not checking logbooks.
