Imagine having the ability to become invisible by blending perfectly into your surroundings and to move before someone’s eyes completely unseen. No longer is this capability limited to the worlds of Harry Potter, comic books, and sci-fi thrillers. Invisibility is the future of military technology. But is invisibility technology a lawful tool of war?

The United States (U.S.) Department of Defense (DOD) is currently funding research in invisibility technology for use in military operations. At least one defense contractor has recently released a prototype of an “invisibility cloak,” academic researchers have unveiled lenses that render the objects behind them undetectable to the human eye, and other companies are developing adaptive technologies for military vehicles that allow them to move unnoticed in any terrain. Once perfected, such technologies will make it possible for ordinary soldiers and special forces alike to advance toward the enemy and operate within its territory undetected. . . .
