If you ever had any doubts, let me remind you of something very, very important: don't mess with the high-tech branches of the U.S. Army. They've just hired Boeing to develop some truck-mounted laser cannons to explode and burn basically anything within sight.
It's all part of the Army's High Energy Laser Technology Demonstrator (HEL TD) project, and they plan to slap a big old laser cannon on a 20-ton vehicle that'll be able to take out incoming shells, missiles, and bombs before they have a chance to hit their targets. With the initial research budget of $7 million possibly getting upped to $50 million, this isn't a cheap project. But hey, it's the Army. They have lots of money to spend on stuff like this, which is why you really should stay on their good side.
