Strike Force 03: FOB SPECTRE | Strike Force: Challenges CoD: BO II Guide
Last update: 11 May 2016
Attention! You don't have to complete the mission to pass the challenge - you have to lose (Mission Failed) or win (Mission Complete), but you can't leave it by exiting it (Quit).
Melee enemy personnel (x10)
It should not be difficult. During the second mission playthrough, on Recruit level, place the soldier at the entrance to the building, on the balcony. Right in front of you the opponents will repel down the ropes - start killing them quickly (first picture above). An even better place is the fence exactly opposite the abovementioned balcony - the soldiers will be passing through it, and you need to wait for them with combatant suppression knuckles (second picture above). Count the enemies - it may happen that the message doesn't appear at once. If you are sure that you have killed at least ten, start doing a different challenge.
Eliminate enemy personnel (x20) using sentry turret
Another easy challenge. As the turret by the electrical power station, keep looking out for the soldiers going down the stairs on the left, as well as for those who have gone through the fence in front of the balcony and entered the small building just to the right. A little later, when the CLAW is destroyed, it is this very turret that will take over its duties (picture above).
The second turret (by the communications uplink) will be firing at the soldiers appearing in an opposite, long "street" (picture above). You can also turn around if any soldiers run near the communications uplink exactly from the other side or run through the nearby door.
Eliminate enemy personnel as CLAW (x10)
You need to repel only three soldiers' attacks to pass the challenge. If you played the mission through in accordance with the tips given in the guide, the challenge should be passed already. Therefore, during the second playthrough (on Recruit level) it is best to immediately direct the CLAW to a place from where it will be able to kill as few enemies as possible - so that it doesn't disturb you in doing other challenges.
Complete this mission with enemy never lowering defence field
The force field will be turned off if you lose any two of the three objects that you are supposed to defend. Try, playing on Recruit level, not to let that happen - it won't be difficult, and the challenge will be yours.
Eliminate enemy ASD (x3) using only sentry turrets
See the challenge about killing 20 enemy soldiers with turrets. The roads on which the ASDs will be going are the same as those on which the enemy soldiers get to turrets (picture above). Just look for ASDs on the minimap.
Eliminate enemy personnel (x20) with headshots
A bit more difficult challenge, as you need to have a lot more accuracy. There are two easiest ways to give accurate headshots. The first is to stand by the fence (mentioned many times) and wait for the enemies who will be passing through it (picture above). Try to shoot as soon as they are on the top of the fence. The second way is more general - don't aim from a distance, but get closer to an enemy at a distance of several meters, then it will be a lot easier for you to aim (but not too close, because then he will start to melee).
Destroy enemy quad drones (x12)
The quad-drones will be flying in groups of four (picture above). Because of the fact that they are the only ones that can fly, they'll always focus on attacking targets you must defend - and these are the places where it's easiest to find them.
Prevent enemy from planting more than one hacking module
You just need to pass one of the previous challenges, namely not let the enemy lower the defence field, and this challenge will also be yours. Hacking modules are small, vertical tubes that enemies place under the last of the targets (at the time when two of the three targets have been destroyed and you have to defend the fourth - the main computer in the building).
Allow no more than one sentry turret to be destroyed
Similarly to most challenges above - playing on Recruit level and being careful a little, so that the enemies don't destroy more than one turret, is enough to pass it.
Complete the mission in "tactical view" only
Immediately after the mission has begun and after you've started controlling any of the soldiers, don't do anything - don't move, don't shoot, don't look around, just press the change view button to go to tactical view. Don't turn it off till the end of the mission.
Don't change the default deployment of troops and play the mission on Recruit level. The only difficulty will be the situations when some soldiers or quad-drones attack one of the targets and there's simply no one to get rid of enemies. The CLAW is too slow, turrets were destroyed or can't reach the targets, and there's no one left in a given place (first and second picture above). That is why, in such cases your soldiers will be important, as they will be the ones to deal with such situations.
The second problem will be the CLAWs. If you send your soldiers at them, they'll die immediately. Therefore, keep your turrets or CLAW ready to repel such an attack (picture above). What's more, you need to manage to point the targets quickly - e.g. quad-drones for the turrets, to prevent enemies from taking advantage of your inattention.
