CREW EXPENDABLE"
Infiltrate the cargo ship. Locate the package.
Intel #1: Within seconds of rappelling onto the ship, you'll head down some stairs and shoot a drunk crew member. In the dark room beside him, located on a desk next to a bunk bed, is the first intelligence item. You literally can't miss it.
Intel #2: After running down a red lit hallway and watching a teammate throw a flash bang grenade, you'll enter one of the ship's large cargo containers. Down the stairway immediately to your right and next to the corpse immediately on your left is the laptop
"BLACKOUT"
Work with the 'good' Russians to rescue your informant, Nikolai.
Intel #3: Run through the swamp at mission's start. After sniping the first group of bad guys, head inside the wooden shack on the left. Next to the television set is the third intel.
Intel #4: Directly across from the room holding Nikolai is a bathroom. Next to the toilet is the fourth laptop. You should be using Night Vision at this point.
CHARLIE DON'T SURF"
Search for Al-Asad.
Intel #5: In the level's very first building, you'll be ordered down some basement stairs and into a long room with cafeteria tables. In the back left corner is a smaller room hiding three terrorists and the laptop.
Intel #6: Before you cross the big open street in the middle of town, turn right and head for the far building with the open doorway and the staircase visible. After dispatching the terrorist, go to the second story to find the intel.
Intel #7: Okay, now cross the street. Go forward until you reach a dusty blue car. To your immediate right is an exterior stairway leading to a rooftop with the seventh laptop. Watch out - enemies lurk up there as well.
"THE BOG"
Break through the enemy lines to find the stranded Abrams tank.
Intel #8: During the Night Vision segment, after unloading the stationary machine gun, you'll see two soldiers kick down a hallway door. Follow them into the small room and look left.
Intel #9: Finish blowing up the tanks with the Javelin missiles. Head through the hole in the wire fence and begin worming through the shanty town. At each fork in the path, turn left. You should do this four times before reaching a flaming barrel, a pair of crooked posters and a large stack of cardboard boxes. Tucked behind the boxes is the laptop. You should really watch the video for this one.
"HUNTED"
Shot down in Western Russia with Nikolai, evade enemy patrols.
Intel #10: Gaz opens a cellar door. After going through the basement and upper floor, you'll be blinded by an enemy's flash bang. Past this encounter, when you're outside again, look for a glowing soda machine. In the large workroom behind it is the tenth intel.
Intel #11: Fight through both greenhouses. After the second one, instead of rushing forward to take on the bad guys, turn left and climb into the dilapidated ruins of the house. Ahead, you'll see a slanted tin roof with some simple wooden tables underneath. On one of the tables is the eleventh laptop.
"WAR PIG"
Escort the Abrams back to the highway. 

Intel #12: As you head into town with the tank, through the towering stone archway, look to your right. See the taller, three-story building? Go to the two-story building immediately past it. Up some stairs are three rooms. The one on the left holds the intel. 

Intel #13: Jump down through the bombed hole in front of you. Cross the street, watching for the store front with clothes hanging in the window. In the back, on the left, is a brown stairwell. Go up and enter the second room on your right. You should see the laptop on a bare cot. 
Intel #14: Near the end of the mission, you'll enter a dark, rubble-strewn room where three of your teammates are shooting at a tank. One soldier holds up his hand to stop your entry. While you wait for them to finish, head a little further down the hall, towards the two small windows. The laptop is here.
"SHOCK AND AWE"
Surround the last of Al-Asad's forces in the capital.
Intel #15: On the upper floor of the building where you rescue the recon squad, search the far right corner. Between two barrels, against the front wall, is the laptop.
Intel #16: Jump down into the courtyard, fight off the terrorists and enter the small structure closest. On the second story, in a tiny closet, is the intel.

"SAFEHOUSE"
Find Al-Asad in his safehouse in Azerbaijan.
Intel #17: After the forest pathway with the white picket fences, enter the first building with the satellite dish outside. On the upper floor, in the bedroom directly across from the stairs, is the seventeenth piece of intel.
Intel #18: Now, with so many houses to choose from, it's easy to get lost. The one you want is above the burning building and below the water tower. On the first floor, in a restaurant booth, is the laptop.
ALL GHILLIED UP"
Crawl through Chernobyl in a ghillie suit.
Intel #19: MacMillan will lead you through a deserted church. Before following him back outside, climb the ladder in the back room. At the top of the tower is the intelligence item.
Intel #20: When you're snaking through the maze of shipping containers, wait for MacMillan to slash the enemy's throat with his knife. He'll go left, but you should go right and through a narrow gap. See the laptop? Right next to the sleeping soldier's feet? Yeah, it's tough, but you can nab it without waking him - or alerting the other two soldiers - if you're extremely slow and careful.
Intel #21: After shooting the sniper on the fire escape, let MacMillan go through the first window. You need to climb all the way to the top and through a higher window to collect this intel.
"ONE SHOT, ONE KILL"
Snipe Zakhaev and escape from Chernobyl.
Intel #22: When you're carrying MacMillan out of the building with the attacking dogs, look for another fire escape to your right. Climb the ladder, climb the escape and grab the laptop.
Intel #23: At the end of the mission, you'll fight large swarms of enemies while waiting for a rescue chopper. At some point in the midst of this battle, a double door on the left (if facing the Ferris wheel) will open to unleash a new group of bad guys. It's back in the shadowy, grassy apartment courtyards you came through to get to this area. Be warned - sometimes the door, for whatever reason, doesn't open. Just kill yourself and keep trying until it does.
"THE SINS OF THE FATHER"
Ambush Zakhaev's son.
Intel #24: The first building you enter in this mission is a diner. Look for the laptop on one of the booth tables. Be quick! The scene will fade to black after a few seconds and transport you to a completely new time and place.
Intel #25: During the foot race, you'll find yourself shooting through a square hole in a tin wall, into a courtyard with several parked cars. Snipe the two men on top of the building, jump through the hole and turn right. Behind the tree is a rusty staircase leading to the intelligence item.
"ULTIMATUM"
Find Sgt. Griggs. Kill the power to the ICBM launch facility.
Intel #26: Wait until you reach the large, junkyard courtyard with the rusty car in the middle. You'll fight many, many terrorists here. The laptop is hidden in the corner room of the L-shaped building across the battlefield.
"ALL IN"
Get inside the ICBM launch facility.
Intel #27: When your team has blown up the wire fence gate, look right. At the end of an alleyway tucked behind the large, red brick building is the intelligence item.
Intel #28: Destroy the tanks and find the arch-shaped aluminum hangar on the right of the battlefield. It's the second one, with the open door. Inside, on the floor and towards the back right, is the laptop.
NO FIGHTING IN THE WAR ROOM"
Reach the control room and abort the nukes.

Intel #29: Upon exiting the flooded restrooms and entering the red lit hallway, turn left. Keep going, past the well lit locker rooms, until you reach the fourth door on your left. Inside the darkened conference room, on the far end of the long table, is the laptop. You may need Night Vision to see it.

Intel #30: On the upper left landing of the mission control room is a conference room with a smaller version of the blue and green world map. The thirtieth and final intelligence item should be pretty easy to spot.
