A proving ground is the US name for a military installation or reservation where weapons or other military technology are experimented with or are tested, or where military tactics are tested. The usual British term is training area.
While these types of facilities are usually military or government establishments, some civilian industries have their own proving grounds for testing prototypes and new technologies.
