Caught in the Loop
After starting the mission, the two targets will be shown in the map. You have to knock down the targets so be careful not to accidentally kill them. The targets are armed so you can use your weapon against their escorts. Once they're alone, close in on them and take them out using your melee attack.
Downtown
These targets will attempt to get away so it will be a good idea to ambush them and stop their car either by grenade launcher or shooting the tires. You can also have a vehicle block their path and just quickly get out of the car to attack them. There will be a lot of cars to use as cover so don't hesitate to engage multiple enemies. You can also use your Focus ability to slow down time and give you more precise shots.
The Beast
The targets are in an armored vehicle. If you have IEDs, you can place a couple of them on the road and wait until the armored vehicle drives over before detonating them. Finish off the other targets using your grenade launcher. If you want, you can also ride the armored truck to add it to your Vehicles on Demand app.
Toll Bridge
There are three armored vehicles in this convoy and they are heavily armed so carry some heavy hardware with you. Pick up a vehicle and head to the expressway. Drive to the left until the lanes merge. From there, you can wait for the convoy to arrive and unleash hell. There might be civilians that will get caught in the crossfire, just recover your reputation by hunting down criminals and preventing crimes.
Chasing Shadows
The target is traveling underground. Your best bet is to find the underground access entrance to the westernmost corner of his projected path. You can set up an ambush there. The convoy has a few elite enforcers so be prepared with some heavy firepower, especially grenade launchers since they're weak against explosives.
Excessive Force
The target's route is short but nearby. You have to knock down the target. Take note that his escorts are all police officers so killing them may lower your reputation a lot. You can knock them out one by one but that will be pretty daunting. If you have high reputation, you can kill a few then just recover it by rescuing potential victims via Crime Detection events. The enemies are heavily armed so make sure you don't rush in carelessly. After knocking down the target, you still have to escape the police.
Long Division
There are two targets that you have to knock down. Their projected path is long so there's a lot of places where you can set up an ambush. If you have the capability to overload steam pipes, wait near one and just blow it up when the targets are near. Take note that their guards are heavily armored and armed so you have to bring your own heavy hardware. Make sure that you also have cover since their weapons can easily take you out.
