Maps and other information are available on the national, regional, state, and local levels that show the supporting infrastructure such as sources and distribution of water, power, natural gas, crude oil and petroleum products, coal, LNG, railroads, roads, sewage lines, ocean and inland waterway routes, barge and ship traffic and capacity, and telephone systems. Information is also available on military base and National Guard unit locations and their equipment such as diesel generators, tanker and other trucks. The data includes capacity and flow-rates. All of this can be put into a computer, with computer displays including overlay maps an numeric data tags on the screen. With this alone, officials can war-game to see the impact of potential threats, both on an area, and on others `downstream' where utility-product flow through the affected area may be disrupted.
