Destruction Measurement is a method of measuring the effective level of havok a singular weapon can wreak. It is a very loose method, and is not based on damage over time or singular rounds, but the amount of damage it can do to a single person (and the collateral, if applicable). It exists to give writers an easy way to gauge how destructive a gun or bomb is without having to pour through the whole article.
