First of all, jump on the other side of the yellow barrier in front of you and proceed to the shooting range. Using the precise aiming, destroy all the dummies and prepare for a fight with a manned turret. To finish him, you must follow the given orders; first of all crouch behind the low wall and blind fire at the turret. After that tell your partner to attack (press the right part of the D-pad twice to do this). The gate in front of you will open and you'll be able to surround your enemy and kill him. That will end this part of training.
You'll find yourself in front of a wooden box. Move towards it and - while running - press [Y] to slide into cover.
Now you have to learn how to throw grenades properly. Choose that kind of armament from your inventory and activate the aim, so you'll see the probable grenade trajectory. To perform a perfect grenade attack, throw it through the façade door.
Characters will move automatically to another part of the camp. Choose your primary weapon and get to the stone wall. From behind it shoot all the incoming enemies. Piece of cake.
Now it's time to express some feelings. Press the [A] button to show your appreciation. The fire button can be used to rebuke your partner. If you press [RB], you'll be able to exchange weapons with your mate.
The next enemy will require sneaking. Order your buddy to hold his position and shoot at the heavy armored guy. You must now surround the opponent and attack him from behind.
Now proceed to the yellow barrier. Turn on your GPS with [Back] button. After that press [RB] and right part of D-pad simultaneously. You'll activate a co-op snipe. Your job is to shoot your dummy, that's all.
Now it is time for a cool maneuver called back-to-back. Enter the circle placed on the ground to start the whole action (it should start automatically). You need shoot at all incoming enemies in a slow motion. Have fun!
Only reviving training remains. When you around the corner, a wall mine will explode and you'll get harmed. Your partner should try to bring you to a safe location and revive you. During that action you must cover him with an accurate fire. Note that if your partner will get hurt, you will have to help him.
