Nitor Group Ltd originally established in 1982 in the UK, comprised multi-disciplined consulting engineers specialising in the design and construction of firearms training ranges. At the outset, services included the full study of needs analysis to determine training requirements; schematic and outline proposals; detailed design, equipment specifications; tender production and contract supervision.

In response to the customer demand, the company evolved into a Prime Contractor for specialised training facilities involving complex turnkey operations, including the supply and fit-out of specialist materials, training solutions and maintenance programmes.

In 1999, Nitor Group Ltd was purchased by Advanced Interactive Systems Inc (Nitor), Seattle a global company providing training and technology in the security, law enforcement and defence marketplaces. Nitor combined state-of-the-art technology and extensive tactical experience to provide immersive, real-life interactive simulated training systems.
