This page of the guide to Far Cry 6 features the walkthrough of operation Firebrand , one of the main missions in Valle De Oro. You will learn e.g. how to destroy Maria's trucks and billboards, how to attack the rum distillery and how to bring down Anton's statue.
Destroy Maria's trucks and billboards
You can start this mission after completing the Guerrilla Radio operation. You must return to Camp Maximas (the guerrilla hideout in Valle De Oro) and meet Talia Benevidez there.
You will receive a message from Talia on your phone with a few pictures of all types of objects and vehicles associated with the two new mission objectives.
The first objective is very general, as you can destroy the objects anywhere in the Noventarmas sub-region. It is best to travel around it in your own car, staying on asphalt roads. Smash the large billboards alongside the road and fire at the trucks you encounter. You have to keep doing this until the progress bar is 100% full.
Note - If you have already destroyed Maria's billboards earlier in the game (e.g. while freely traveling through Valle De Oro), the progress bar may be partially full already at the start. This will allow you to complete the mission objective faster.
Attack the Marquessa Rum Distillery
For this mission objective, you must visit a specific rum distillery. You will have to destroy the red crates and tanks. You can use any weapons and explosives to do it. As before, the damage progress bar must reach 100%.
If you cause the required damage before dealing with all enemies in the distillery, you will have to escape from the location - you just need to get far away enough from it.
Destroy Anton's statue
You need to get to El Presidente Square with the large statue of the tyrant - this area is south of the city of Esperanza , and you should expect at least one enemy outpost along the way. It is best to secure it, so that you will be able to get to the capital more easily later in the campaign.
You can destroy the statue in several ways. For example, you can use the rocket launcher you have, or look around for an enemy tank that should be driving around. This will allow you to use an EMP grenade or the Volta supremo on it, take control of it, and use the tank's main gun to fire at the statue.
You will complete the operation regardless of the chosen method.
