Simple yet effective challenge

[MLdB]

The damage done by a missile = Missile-Damage * (Random number between 1 and 8, inclusive)

that's an acceptable inaccuracy of specifications even for Lockheed Martin

defense ministry: "and what did you say the effective range of this nuclear missile was?"
lockheed: "a pretty random distance"

or better:

boeing: "yeah, there's a fair chance this saturn V baby will go up to some random extend... what?... the moon?... is that 'up'?... "

He meant that the damage done by any projectile can be up to 8 times its missile damage value and as little as the missile damage value itself.
