New technology that can make tanks invisible has been unveiled by the Ministry of Defense.

In secret trials last week, the Army said it had made a vehicle completely disappear and predicted that an invisible tank would be ready for service by 2012.

The new technology uses cameras and projectors to beam images of the surrounding landscape onto a tank.

How the technology works in a combat situation is very sensitive, but the MoD is believed to be testing a military jacket that works on the same principles.
