Microsoft has won a United States military contract worth up to $21.9 billion that will see the Xbox and Windows company build custom augmented-reality headsets for the US Army. Microsoft said in a blog post that it is creating a new Integrated Visual Augmentation System (IVAS) for the US Army based on its HoloLens and Azure cloud service technologies.

Microsoft said the new device "delivers a platform that will keep soldiers safer and make them more effective." The programs running on the headsets offer "enhanced situational awareness" to help soldiers in a variety of ways. Microsoft will create 120,000 of these headsets and deliver them to the Army over the next decade as part of the deal.
