In Operation Whirlwind your mind is the ultimate weapon in this unique war game. Strategy, not force, is the key to victory as you move your battalion through a series of testing skirmishes and battle actions. Your ability to command, to give orders, and to move your troops skilfully determines the success of your assault and combat operations. Operation Whirlwind requires the concentration of chess - a typical game may take between one and three hours - and the ability to master the many tactics of waging full scale war.
How well you can focus your strategic energies will decide whether your victory is Questionable, Marginal, Tactical, Strategic or a Breakthrough. A great game for the thinking game player.
