Terminate with extreme prejudice

In military and other covert operations, terminate with extreme prejudice is a euphemism for aggressive execution (playing on the expression "termination with prejudice" of an employment contract). In a military intelligence context, it is generally understood as an order to assassinate. Its meaning was explained in a New York Times report on the Green Beret Affair (an incident during the Vietnam War), and subsequently popularized by use in movie Apocalypse Now.
