wikipedia - 15 Oct 2021The SGR-A1 is a type of sentry gun that was jointly developed by Samsung Techwin (now Hanwha Aerospace) and Korea University to assist South Korean troops in the Korean Demilitarized Zone. It is widely considered as the first unit of its kind to have an integrated system that includes surveillance, tracking, firing, and voice recognition.[1][2] While units of the SGR-A1 have been reportedly deployed, their number is unknown due to the project being "highly classified".[3]
