area was developed during the 1970s by the 7th Infantry division
and utilized as an advanced training area. The training area
included a small town (called Dodge City) that had pop up shooting
targets of bad guys and good guys. In the late 1980s the Impossible
City was built to train the infantry in urban assault tactics.
Impossible City derives its name from the way the city is built,
all areas can be easily seen from adjacent buildings, and most
doors open to a central area. Today the facility is run and
used by the FBI for urban training. The FBI subleases the area
to local law enforcement agencies and military units such as
the Navy Seals. This area is off limits to the general public.
