Helldivers Objective - Activate and Defend Launchpad (Cyborgs)
With Cyborgs, these are toughest on Forest maps when they are placed with water on all sides, especially if you also have AA Gun placements preventing Stratagem Call-In's within their radius. Snow can also be tough if they don't have a bunch of Sprint friendly ice around them.
Obviously if there are any AA Guns that would block Stratagems Call-In's, take them out first. Aside that it is really about making sure the Rocket side is guarded (keep it on screen with at least one in the team guarding it) and trying to ensure any killing taking place is happening as far away from the Rocket as possible and preferably on side that is away from the Rocket. You can influence which side they spawn / alarm by calling in Stratagems in those areas and / or letting alarms go off and then do lot of rapid killing in those areas so game keeps busy respawning more in those killing zones. Always be prepared for some other enemies to sneak up from a different direction and raise their own alarm and possibly drop Warlord / Hulk etc too near your objective.
You can use any combination of Stun / Slow or AT to control the situation in your favor. The most important thing is really how the team forms around the rocket and covers their own sides for most part, and get help only as needed.
This video contains 3 Activate and Defend Launchpad objective completions that I feel demonstrate the guidance I have shared above. The first is a 2P with RAN_RED, the second is a solo, and the 3rd is 4P with randoms.
Note: If you leave the area while countdown is still active, you will automatically fail the objective.
