In this section, the interplay between a single M825 WP round and a given built environment is examined at the scale of a single building.

• Photographic documentation from the ground during an actual WP deployment is studied and the behavior of wedges is examined in relation to a range of architectural features. A series of scenarios are isolated and their anticipated effects described.
• A series of computer-assisted simulations of such deployment are run over a typical urban residential area, in a significant number of iterations. The resulting points of impact of WP wedges are counted and sorted by type of architectural surface impacted. The data thereby assembled is analyzed, and statistical conclusions are drawn about the probability of specific damage scenarios.
