After that, use one of the parked bikes to go to the Merryweather warehouse.
When you get close, equip a suppressed weapon.
If you approach the warehouse from the west, you will see a single guard directly ahead of you. Take him out with a headshot.
Continue moving forward and wait for another guard to pass by the containers. Take him out as well.
Go left, and you will notice two guards chatting by the tractor. Take them both out.
Jump over the fence, and you will see another guard out in the distance, take him out as well.
Now move towards the front entrance of the warehouse and take out the guard closest to you.
You will notice two more guards directly ahead of the guard you just eliminated. Take them both out as well.
After that, go right and behind the warehouse. You will find a single guard here. Take him out before running back to the front.
You will find another guard in the distance by his jeep. Eliminate him.
Now, you can eliminate the guard to your right, standing next to another vehicle with its bonnet open.
Now, there's only one guard left. Go behind him and take him out with a headshot.
Make your way to the warehouse and stay in a stealth position.
As soon as you enter, you will notice one guard directly ahead of you welding. Go for the headshot.
Then turn right, and you will see another guard crouched beside a shelf. Take him out.
Moving forward, you will find another guard crouched next to a generator. Take him out.
After that, take out the guard on the right.
And then the one on the left next to some wooden crates.
Keep moving forward, and you will find another guard on the left side of the office. Take him out.
Now, you can take out the final two guards inside the office by shooting through the window.
After eliminating all the guards, start collecting the crates. They are generally in the same spot. But if you don't find them, just run around the warehouse, and they will automatically be marked as green dots on your minimap when you get closer.
Crate 1
On a stack of wooden pallets next to the office.
Crate 2
On a workbench on the right side of the office.
Crate 3
On a metal shelf to your right as soon as you enter the warehouse.
Crate 4
On a shelf on the left side of the office.
When you grab all four crates, go to the Rumpo (Van) and deliver all the crates.
After that, drive the Rumpo and exit the warehouse.
Now you need to deliver this to LSA Lockup. If you thought of using the Avenger to deliver this Rumpo easily, you're out of luck as Merryweather destroys your Avenger!
Your only option is to drive the Rumpo all the way back to the city and deliver it to LSA Lockup.
As you drive it back to the lockup, you will get two bars at the bottom-right corner of your screen. One is a lock-on meter, and the other is a speed meter.
Some Merryweather guards and a jet will chase you. The speed meter has a black line. Keep an eye out for this bar. Make sure the speed bar doesn't go below the black line. If it does, the lock-on meter will start to rise.
If the lock-on bar is filled, the jet can lock onto you and eliminate you.
Shortly after, you will get Rooster's air support. As long as you stay inside the blue region (as seen on the minimap), the jet won't be able to lock onto you. The meters will turn grey suggesting you are not safe.
Once you get on the main highway, it is a breeze. Drive back to the LSA Lockup to complete the mission. It is also worth noting that the jet and the Merryweather stop chasing you as soon as you enter the city.
With the cargo crates secured, prepare for a rescue mission in Unconventional Warfare.
