The US military builds dummy towns for training purposes. This is called "MOUT" training, for Military Operations in Urban Terrain. The current ones look like towns in Iraq, Iran, Afghanistan, etc. The National Training Center at Fort Irwin, CA has the biggest one.[1]
(There's a very good reason for that sort of thing. Most infantry casualties are among soldiers new to combat. Very realistic training means that most noob mistakes happen at a training facility, not in combat. Armies that don't do this have huge casualty rates at first.)
