"The system maintains a human-in-the-loop control for fire decisions, and it cannot decide to fire autonomously." well, I am sure the human will make the right decision on who to shoot.
Probably but I also know for a fact that development was done with DARPA and they were strapping guns to that thing before it was even publicly shown. When DARPA pulled funding later they said it was due to it being too loud for combat.
The goal was always to use this as an assault device of some kind.
iirc thats because batteries are too heavy/dont last long enough for military work so they had to power it with essentially a go-kart engine, making it almost as loud as a truck and ruining the stealth of any infantry unit its attached to like a humvee would. infantry often depend on stealth to maneuver into position so thats a no go for now but it wouldnt matter as much to police probably.
