Classified details of army's Challenger tank leaked via video game

Classified details of the British Army's main battle tank, Challenger 2, have been leaked online after a player in a tank battle video game disputed its accuracy. The player, who claimed to have been a real life Challenger 2 tank commander and gunnery instructor, disputed the design of the tank in the popular combat video game "War Thunder", arguing it needed changing. He claimed game designers had failed to "model it properly". To support his argument the player posted pages from the official Challenger 2 Army Equipment Support Publication – a manual and maintenance guide. Excerpts from the documents, some of which were heavily redacted, appeared to show some documents had "UK RESTRICTED" label crossed out and a stamp of "UNCLASSIFIED" added, the website UK Defence Journal reported.
