Right now UGV's always keep their lights on when it's dark. The UGV's don't need lights for one thing. But if no one is in control of them they are easy targets for enemies. Since they are autonomous they make excellent guardians and if enemies see them they don't stand a chance. They have night vision and infared. They should be set to lights off as default and only turn lights on when told to.
We need to be able to set them to stealth mode. Either by mission makers or ugv controller giving them waypoints. They should still follow same orders as regular units. With the new modules, you can sync a "set mode" module with "stealth" selected. They can also trigger back on.
