UGV
General
Dismount squads may now drop an unmanned ground vehicle (UGV) which can be remotely controlled and provides thermal and optical camera views from locations up to 300m away.
If the vehicle is steered beyond the range of the remote control (300m), the UGV will automatically turn around and try to return to the squad. To pick it up, you must be close (20m or so).
Commands
If your squad has one (the UGV has to have been "given" to the infantry in the mission editor), hit Z while dismounted. Switch to F2 for "remote control view" that will follow your UGV, so your WASDX commands don't steer the squad but the UGV. F3 gives you the camera view of the UGV. Use Q and Z to elevate and retract the sensor mast. N and Shift+N will control the zoom. Num+ switches from day channel to thermal sight, and back.
Mission Design
In reality only CV90 squads use these but in PRO PE any PC can be equipped with it (in the mission editor, select a PC and check the "UGV" item).
