Helldivers Objective - Escort Convoy (Cyborgs)
With Cyborgs, these are toughest on Snow or Forest maps where you can have restricted mobility during all or parts of it. The good news is the rail track itself is always restriction free. On Forest some parts of the track might also be covered by AA Guns.
There are two main threats to the Escort Convoy.
The IFV are best left crippled and especially if one is in your rear even not crippled, think twice before destroying because next could spawn in front of or on top of your Convoy.
The Warlords are the real challenge because if they get close to the convoy, they are very hard to kill without also damaging / destroying the Convoy. Use of Stun options like RX-1 Rail Gun, Stun Grenades, Stun Mines, and Static Field can be much better options than ability to blow them up.
The Hulks are less dangerous, but can pose same risk as Warlords if they get too close. If you get Butchers you can neutralize them by just tagging each of them with your Primary fire so they divert their attention to you and start ignoring the Convoy. Either way, best to Stun and leave behind.
While engaging in battle, don't let Convoy get too far ahead or behind off-screen or it will fail automatically if not by coming under fire by other enemies. Practice good formation and try to keep all the enemies / fighting in your rear.
