There was video floating around of a machine gun turret being remote controlled using the Valve Steamdeck in Ukraine.

Edit: consumer joysticks normally use potentiometers, which aren't great for deadzones/drift. For things like dust incursion reasons along it would make sense for any industrial/military device to be using hall effect based joysticks.

The more modern ones use hall sensor based sticks. Most new RC transmitter designs have 'em.

Valve donated few of those for kids. Most likely one of those units, than purposefully chosen.
