The US military is working on an "invisibility cloak" which would hide its troops from enemies.
The Defense Advanced Research Projects Agency (DAPRA) announced the new invention would be made of a "smoke-like obscurant" to replace the current controversial white phosphorus which has seen some soldiers left with burnt flesh.
It is currently early days for the device but DAPRA have revealed the 'cloak' could be made up of liquid aerosol spray or engineered material, adding: "It will be deployed in specific ways to allow one-way vision through the plume."
