Submarine fleet 1 | Caimanes Walkthrough Ghost Recon: Wildlands Guide
Last update: 26 January 2018
In "Submarine fleet 1" you need to find and destroy a hidden drug submarine. It's in the north part of the base. Don't start from the land but rather swim towards your target. This way, you won't have to fight the entire squad.
Once inside, plant C4 on the submarine. Don't detonate the charge right away, and move to a safe distance. Hostile soldiers will not detect you and one bomb is enough to destroy the target and complete the mission.
