Such training areas are run by the military and are normally out-of-bounds to the public who may sometimes be allowed access during weekends or holidays.
Military training areas are often important wildlife refuges and can make a "significant contribution to conservation... if properly managed."
This is because they comprise large tracts of countryside with restricted access and are free from development, cultivation or other exploitative activities.
They are run by "Military Regions" and have been used since 1994 for joint exercises and training between the Czech armed forces and its allies.
In addition, since 2001, the armed forces of Austria, Belgium, France, Hungary, the Netherlands and the US have conducted national exercises on Czech MTAs.
