CommonCog ran a tactical decision game for their subscribers. It's a military tabletop exercise where you command a unit in a tactical scenario and your task is to give orders. The facilitator and the other participants will then poke holes in your thinking, and then it's turn for the next participant to give orders. This teaches you to make sense of the situation and to give orders - to think on your feet.
