Back in 2018, Microsoft found itself in the middle of a controversy after selling $480 million worth of HoloLens headsets to the US Army. Employees spoke out against the decision at the time, but Microsoft stood its ground. Now, Microsoft has signed a much bigger contract with the military, selling $21.88 billion worth of newer HoloLens tech. HoloLens tech has been used for the IVAS (Integrated Visual Augmented System) concept, which uses the AR display to show a map, thermal imaging and aim for a weapon. Under the new $21 billion contract, Microsoft will mass produce 120,000 custom HoloLens/IVAS headsets for the US Army.
