True. But terrain can also be a major obstacle. In some terrain these vehicles would easily get stuck. Iran needs a tracked version of the first vehicle. But Iran would need to have intel on the target before hand in some situations before sending these in. If the range is only 2km radius and terrain is favourable for tanks, while Nazir searches for a target it would already be taken out. Or if enemy has assets in the sky it would mean these UGV’s won’t even get close since range is only 2kms.They are short range UGVs, 2 KM in radius. EV is an issue but at this range, it wouldnt be important esp for a UGV moving on the ground.
IMO a better option would drone based atgm with AI that can them self identify and take out targets. All Iranian would need is a drone launcher near enemy formations and the drones will do the rest.
