who has only 15-20 barracks?
My question would be, who builds that many barracks? I generally build one for about every five cities or so. Strategically located so that upgrading can be accomplished in that city's region in a few turns of unit shuffling and in cities that will be producing a lot of ground units. If I get Leonardo's, the big upgrade to infantry and artillary at replaceable parts means that I can achieve any reasonable military objective that I desire before the AI can get off the ground in upgrading/building new units. This can include taking Sun Tzu's, taking out the most powerful AI, or clearing out the neighborhood.
