The Combined Arms Tactical Trainer (CATT) is the British Army's primary tactical battlegroup simulator, consisting of over 150 networked simulators which replicate the interiors of armoured vehicles.
[1] It has sites at Warminster in Wiltshire (near Waterloo Lines) and Sennelager in Germany, which can be operated separately or inter-linked.
[2] Built in the 1990s[3] and in use since 2002, the system is a development of the United States Army's Close Combat Tactical Trainer.
[4] The simulator can train up to 450 military personnel on a virtual battlefield,[5] and is run jointly by the Ministry of Defence, Lockheed Martin and BAE Systems.
[2] In 2005, the total cost of the program was stated to be £238 million, and the Defence Procurement Agency claimed it was the largest and most sophisticated virtual training facility in the world.
