The approach is applicable to urban combat, and takes into account mass gatherings of people located in highly complex urban structures, incorporating features such as multi-level buildings, open spaces between buildings, crowd congregation points, and transport hubs.
As well, the 3D tactics cube notionally conforms within 300 m2, which gives coverage to most weapons effective ranges, and incorporates most CBD buildings.
This was a tactical formation designed by US Army Air Force heavy (strategic) bombers during World War II.
3D illustrations were often used in the World War II period, as a means to visualize how heavy bomber formations would defend themselves against enemy interceptors in the absence of escorting fighters, by providing interlocking fire from each of the planes operating in mutual support.
[13] Geographic information system (GIS) approaches have been significant in recent times influencing the development and conceptualization of 3D tactical analysis.
