Previous: Destroy the Barricade
A pretty easy mission if you have the sneaking suit. Play it once or twice to suss out the location of the enemies, then you can run past most of them for an S rank.
Once you reach the cut scene where Snake has to find the Nukes from the trucks, find the truck with license plate 63824. This will allow to you recruit Hideo Kojima, and will gain you a trophy.
