Helldivers Objective - Disarm Unexploded Ordinance (Cyborgs)
With Cyborgs, these are toughest on Snow maps where your mobility might be restricted.
The best thing to do is for 1 of the players to call in the ME-1 'Sniffer' Metal Detector Special Stratagem that is available when these objectives are still left on mission well before getting to the Objective area, and then let that player find and disarm each Unexploded Ordinance that needs to be disarmed while being covered by the others. It is not a good idea to call down stuff while at the objective if you already have at least one Sniffer because that just attracts new scouts to your position. If things do alarm, it is important to move as a team with good coordination so players don't get screen locked or have no escape paths and keep focus on the objective and keeping each other alive instead of being distracted by the endless fighting that can take place.
This video contains 3 Disarm Unexploded Ordinance objective completions that I feel demonstrate the guidance I have shared above.
Note: If you have Displacement Field Perk or SH-20 active you can purposely miss-dial the disarm code and let the active Displacement Field or Shield save you. Doing so does not fail the objective, but make sure no allies are in the blast radius. Alternatively if you are fast enough you can also LIFT-850 out of blast after miss-dialing (much riskier). You can also dive for cover out of blast after miss-dialing but you have to be positioned just right before you miss-dial to be able to dive for cover away from it (very risky). Generally better just to dial the disarm codes while team has you covered.
Note: If doing this solo, find some way to either avoid alarms (Smoke Grenades Perk, etc) or incapacitate your enemies (Static Field Conductors, AT Mines that cripple IFV, etc) so you have time to find and dial disarm. While doing this solo highly recommend use of SH-20 as it will at least neuter the Hound threat.
