Army chief reveals latest laser weapons tests
By 2023, the US Army says it will be able to blast drones out of the sky using lasers. 
 
In a step towards that goal, It recently conducted an early trial of a truck-mounted laser cannon at Fort Sill, Oklahoma.
Soldiers used the laser system, also known as HELMTT, to successfully destroy a quadcopter drone, completely melting its casing and internal circuit. 

'We did a lot of preparation…seeing if we could track the airborne targets among ground clutter,' Adam Aberle, the program manager in charge of the High Energy Laser Mobile Test Truck, or HELMTT, said. 'We absolutely blew lots of stuff up.'
 
The team also used the laser to 'completely destroy' a laptop as a demonstration of how the system might be used to disable enemy command and control systems.
'It melts all the plastic, fractures the screen, and basically renders the laptop unusable,' said Aberle.  
 
HELMTT includes a 10-kilowatt laser - equivalent to about 10 million handheld laser pointers.
