Abstract: The present invention generally relates to a method and apparatus for circulating air through a modular unit configured for live fire training exercises. In one aspect, a modular unit is provided. The modular unit includes a body having an opening formed therein and at least one bullet containment member. The modular unit further includes an active airflow ventilation system disposed on the body and configured to enclose the body and to circulate air through the body. The ventilation system includes a plenum, a ceiling member configured to allow airflow into the plenum and an air control unit configured to circulate the airflow through the plenum. In another aspect, an active airflow ventilation system for use with a shoot house is provided. In yet a further aspect, a method of circulating air through an enclosed modular unit configured for use in live fire training exercises is provided.

Abstract: The present invention is generally directed to a reconfigurable armored unit for use in live fire training exercises. In one aspect, a reconfigurable training facility is provided. The reconfigurable training facility includes a first modular unit having at least one subsystem and a second modular unit having at least one subsystem. Each modular unit is constructed from a standard structural footprint and each modular unit includes at least one bullet containment wall. The reconfigurable training facility further includes a control member, wherein the subsystem in each modular unit is controlled by the control member. In another aspect, a modular unit for use in a reconfigurable training facility is provided. In yet another aspect, a method of forming a reconfigurable training facility is provided. In a further aspect, a method of building a scenario in a graphical space is provided.
