In order to destroy a "hard" target an attacker vifl use a por,rerful warhead, unless he has a rnissil-e of higb accuracy. l'{issile accuracy is usually given in terBs of the circular error probable (CEP), defined as the distance from the target within vhich, on the average, ha]-f the re-entry vehicles ni1l lanil if ainecidirectly at the target. tr'or exanple, a 1Mt. nuclear lrarhead nay be needed on a uissile r+ith a CEP of l- kn, in order to destroy a particular hardened structure.

**Analysis**
The text appears to be discussing military-related topics, specifically nuclear weapons and their capabilities. It mentions concepts such as yield, area destroyed, equivalent tonnage, and circular error probable (CEP), which are all relevant to the military and defense industries. Additionally, the text mentions specific types of delivery vehicles, such as intercontinental ballistic missiles (ICBMs) and submarine-launched ballistic missiles (SLBMs).
