Brezhnev is said to have been so fearful of attempts being made on his life that he kept five versions of himself on hand at all times. Each so closely resembled him that he himself would have been unable to tell himself apart from himself, so it's a good job they told him who he was. That was why he also had five Chaikas, so if a Chaika pulled out of a Kremlin gate, in reality five Chaikas would pull out of five Kremlin gates, each identical to a hair, with an identical him seated behind the tinted windows in each, so that any would-be assassin would have been more than a bit confused, if he saw all five at once, which one he should aim at. And if he did not see them all at one and the same time, the assassin would simply open fire, giving Brezhnev a one in five chance of dying (or four to one of living).
