Helldivers Objective - Perform Geological Survey (Cyborgs)
With Cyborgs, these are toughest on Forest maps where they tend to have AA Gun placements preventing Stratagem Call-In's within their radius near objectives.
The first thing any team should do is get rid of the AA Guns if any are in the immediate area. Next if there are any Cyborg IFV nearby (especially on side that Drill will drop), they should try to cripple them with Anti-Tank Mines or EAT-17 / Recoilless shot at non-perpendicular angle to one of its corners (center and / or perpendicular shots tend to kill more than cripple). Beyond that anything they like to use to Stun / Slow and otherwise keep Cyborgs suppressed should be all that is needed with special attention only given to any new IFV or Warlords and let one on the team focus on dialing the 5 code sequences required to complete the objective.
This video contains 3 Perform Geological Survey objective completions that I feel demonstrate the guidance I have shared above.
Note: If you are getting overwhelmed or playing solo and unable to keep them suppressed for full duration, you should know that unlike Escort Convoy and Activate and Defend Launchpad objectives you are allowed to get far away from Perform Geological Survey objectives even after activated. In fact you can use this tip to move between multiple Drill sites and just do next sequence of codes and then run away quickly should a scout party show up and alarm. As long as you get far enough away quick enough it will remain safe and you can return to it and repeat similar strategy until the 5 sequences are completed.
Note: Regarding Rumbler ability to take out AA Guns, land the shells on ground in front of it rather that directly on it for more consistent results. This tip I learned from RAN_RED.
