Dozens of Microsoft employees have signed a letter protesting the company's $480 million contract to supply the U.S. Army with augmented reality headsets intended for use on the battlefield.

Under the terms of the deal, the headsets, which place holographic images into the wearer's field of vision, would be adapted to "increase lethality" by "enhancing the ability to detect, decide and engage before the enemy," according to a government description of the project. Microsoft was awarded the contract in November.
