This autonomous gun is capable of independently identifying targets with its thermal optics, identifying their range with its range finder, then engaging them at ranges up to 1.2 miles (2 km) with its Milkor MGL 40mm grenade launcher or its Daewoo K3 5.56 machine gun.
I’m reasonably sure they’re not turned on all the time. I’m assuming there’s a “in case of invasion break glass” somewhere, with the power switch inside.
