Sniper Ghost Warrior 3

This description is wrong, it is actually obtained from tagging 10 enemies with the CCTV system.
The CCTV's systems can be hacked either remotely with your drone (if you have that module) or by walking up to one of the control panels and doing so with . These are not located at every outpost, but the ones that do have them will obviously have cameras. A good one that I found to try was in the second map, Village on the NW side of the map (See below).



Approach from the east via the cliff, watching out for the mines planted on the trail. There is a CCTV server that you can hack on the roof or on the southern facing side of the buildings. Easiest one to get to is probably the one on the roof if you kill the soldier up there. Hacking this will give you approx 5-6 cameras in and around the buildings to tag enemies. You should easily be able to get this using this single CCTV system if you did not tag any enemies manually with your gun or drone.
