WWII Style US Army barracks.
These buildings existed in the in 1940's through at least the 1980s and some remained after that. This structure is modeled after the barracks I stayed in during my basic training and advanced training at Ft. Sill OK in 1983.
Model measures 2.52" x 1.25" x 1.54" tall (64mm x 32mm x 39mm). Building is very generic in design to allow it to be used in all regions of the world and all eras from WWII through today.
