Mission 2: Little Resistance

1. Watch the cutscene as your boat heads closer and closer to shore. You will be launched into the water. When you wash up on shore, you'll be able to control the character.
2. Your first goal is to call in rocket strikes. Push <- on the D-pad, aim at the desired location (straight ahead, the big cluster of enemies), and push RT to fire.
3. Move forward with your fellow soldiers until they crouch down in a small pit. From here, right up and to the left. Up ahead, you can push X to bayonet an injured enemy. Do so, if you like.
4. When you come up to a clearing, with a bunker to the right, call in an airstrike to take it out.
5. After doing so, stay crouched behind the nearest barricade, as enemies will flood out into the battlefield. Use airstrike again, aiming it into the deepest cluster of enemies in the battlefield.
6. Proceed to mop up the remaining enemies in the battlefield. Once the coast is clear, cautiously move forward. You will encounter more resistance, but in fewer numbers. Bayonet anyone who gets too close for comfort, pushing X to do so.
7. Strategy: Remember, if a grenade is thrown your way, quickly press RB to throw it right back.
8. Head to the left of the battlefield. Go slow, there is a tank straight ahead. Head straight through the trench.
9. Strategy: When you come to a long corridor in the trench, you'll notice some barrels that look suspiciously flammable near the enemies up ahead. Shoot the barrels for some easy, explosive kills.
10. Stay behind the first set of crates while finishing off any remaining enemies, then proceed through the trench.
11. Be ready for an ambush coming from the right side. It's just one soldier, no problem.
12. Checkpoint Reached
13. Roebuck will tell you to watch the tree in front of you. Shoot the soldier who is climbing up.
14. Achievement: If you jump and look just to the right of the tree base, you can see a camouflaged soldier hiding. Lay down some gunfire in his direction until you kill him, obtaining "Snake in the Grass."
15. Achievement: Another soldier is waiting in the grass to the left. Approach him, and if he knocks you down, fend him off by pressing RS to secure "Close Shave."
16. Another cluster of soldiers await in the grass. Backpedal while shooting to take them out with little fuss. Continue through the path until you reach a clearing.
17. Checkpoint Reached
18. Your next objective is to attack the Japanese bunker to your left. Instead of fighting head on, move straight through the clearing in the same direction from which you approached to an underground passage across the way.
19. Shoot the few soldiers inside the passage and follow the tunnel all the way through.
20. You should have a clear shot at most of the enemies attacking your men. Take them out, then turn right so you are looking at the bunker.
21. Strategy: Use the tree between you and the bunker as cover from machine gun fire. When you reach the bunker, turn around and shoot any remaining enemies in the clearing.
22. Death Card: Go back to the tree and look on the side away from the bunker entrance. You'll see the "Four of Clubs." Move inside the bunker.
23. Checkpoint Reached
24. Climb the ladder, then turn so you're facing the same side of the bunker where you entered. With any luck, the enemies manning each machine gun won't notice you, allowing for a couple easy revenge kills.
25. Head through the doorway to your left and walk straight to the wall, where you have a clear view of the mortar pit below. Roebuck will tell you to call in a rocket strike on two enemy tanks.
26. Achievement:' Press -> on the D-Pad to set up the strike, but instead of focusing on the tanks, aim at the patch of enemies towards the front left section of the mortar pit. Press RT to call the strike on them, earning "Weapons of Mass Destruction."
27. The first tank is located directly behind the soldiers you just blew up. Call a strike on that one first. The second tank is located to the right of the mortar pit, and further back. Call the second strike and watch the fireworks.
28. Turn left and head through the doorway to where your buddies are waiting. An enemy soldier will burst through the door in front of you and stab Sullivan. Get revenge and watch the chapter end as Roebuck tries to tend to your fallen comrade.
