'Invisibility cloak' for tanks
This was on BBC.com a couple days ago, but didn't see it posted here. Apparently, BAE has come up with a camouflage system for tanks, that can help them hide from IR cameras/scopes.

Kind of reminds me of the Mirage Tanks from Red Alert 2.
It can also make a tank look like other objects, such as a cow or car, when seen through heat-sensitive 'scopes.
