Remaining A Quiet Exit - secondary mission objectives | Walkthrough MGS V: TPP Guide

Extract 7 tanks and 7 armored vehicles

Sneak up to APCs only when they are occupied with fighting Quiet

It's an incredibly difficult objective - you must extract fourteen (!!!) vehicles that attack Lamar Khaate Palace. Try to complete it while replaying the mission, because you need the best possible equipment.

All of the vehicles enter combat mode when they reach the battlefield, which is a major difficulty. You won't be able to sneak up to all of them. There are two solutions. The first one means that you count on Quiet and wait until tanks and APCs engage in fighting her. The downside is that Quiet might start losing health points.

Another solution is just placing mines on the roads that the vehicles use. It guarantees better results, but you need to take care of two things. First, you need to know the order in which vehicles appear and place the charges underneath them. Second, you must use mines that do not destroy the vehicles (e.g. EMP).
