All five crates of this chapter are at the railway station that you visit towards the end of the chapter and where you are to avoid the enemy chopper. It is necessary not necessary to reach the crates in the order presented here. In each one of them, there is an RPG that you use to shoot the helicopter down.
The first crate is in the left part of the station and the bad news is that there is, at least, one opponent nearby. It is best to eliminate him quickly and loot the crate before other opponents come round.
The second crate is in the right part of the train station. You will find it in the back of the truck shown in the above screenshot. Before you get there, clear the nearby building of the enemies.
The third crate is also in the right part of the train station. It is a bit farther ahead, next ot the bridge above the rails.
The fourth crate is inside the car shown in the above screenshot in the central part of the station. It is under the bridge under the rails. This area is being watched over by an enemy sniper, but after you enter the car, you will not be bothered.
The last crate is at the other end of the train station, next to the tall wall and the locked gate. There should be no opponents around, so you will not be bothered.
