The U.S. military is dreaming of using microwaves, laser beams and high-powered sonar weapons to unleash on its enemies.

The fantasy wish-list, called the Non-Lethal Weapons Reference Book, was leaked online last week by PublicIntelligence.org. The U.S. military enlisted the help of the Joint Non-Lethal Directorate to produce a reference book that describes weapons already in-use and weapons that are still fantasy. It's like a secret Christmas list for military and law enforcement officials for weapons that seem like they pulled from science-fiction. The non-lethal aspect of the weapons doesn't mean that they aren't going to hurt but it does make it easier for the military to win the populace's favor by not killing them outright.

"In past operations, the effective employment of NLW resolved escalation of force situations," the document states. "Specifically, the NLW created the right 'direct effect' on the personnel/materiel targeted. The use of NLW has also generated positive 'psychological effects' on others in the area and helped to contribute to mission accomplishment."

The document which runs over 100 pages, describes 14 weapons that are already being field-tested and other weapons that are still in the developmental stages. One example is an "Impulse Swimmer Gun" that uses pulsed sound waves to cause "auditory impairment and/or nausea" among underwater swimmers and divers who are swimming or diving where they shouldn't be.

Other projects include a portable microwave system that can emit high-powered microwaves to stall a car engine. There's also a plan for an unmanned, airborne vessel can trigger an "electrical system malfunction" on enemy ships. Also on described on the document is a Distributed Sound and Light Array that uses lasers, other lighting and acoustics to disable enemies.

One ambitious project is the Laser Based Flow Modification system which will be used to alter the route of enemy aircraft. A system of lasers will be placed on a tip of an airplane to control the steering forces of an enemy aircraft and divert from its target.

Some weapons are being upgraded like the Raytheon Active Denial System. The system heats up the skin of the target without causing injury. The beam cost $55 million to develop and it was canceled in 2008. It saw action in Afghanistan two years later where it suffered from logistical and technical problems. Now the weapon is being re-designed for a better model. The next generation ADS will be smaller and will be able to shoot-on-the-move. The military would also like an aerial ADS to shoot those pain beams from above.

There's no timetable when these weapons will ever see widespread use or even if they will even get off the drawing board, which could be a good thing considering you wouldn't want to be hit with one of these weapons no matter how non-lethal they might be.
