At this year’s KADEX 2018 held in Astana, Kazakhstan, the Kazakh state-owned GIS Center had a virtual reality headset that is designed to work with a Kalashnikov-patterned service rifle. The headset portion integrates (and likely licenses) software from a Russian entity called VR Concept, which produces VR solutions for a wide variety of applications.
The device was covered by a Kazakh reporter of Astana TV in this segment on the defense exhibition. It appears that the reporter was able to maneuver a defensive position through the headset, whatever his field of view was on a public television screen.
