The Fuzzy Wuzzy Fallacy is a name for a wargaming theory coined by Richard Hamblen in the September 1976 edition of the Avalon Hill General wargaming magazine, loosely based on historical records of battles between the British and the Sudanese Mahdi. The Fuzzy Wuzzy Fallacy states that a single soldier with 2× firepower or attack strength is not equal to two soldiers with 1× firepower or attack strength. Instead, the soldier with 2× firepower is actually worth sqrt2 of the 1× soldier, if either soldier can be killed in a single hit. This is another form of Lanchester's law.
As a result, tactics and strategy designed around this theory emphasize greater numbers and time, which the speed and mobility of the units in action can effect.
