The Hunted
-Sinistar
Upon crashing, head to the crashsite and take the weapons available to you. You don't have the night vision, but the M4A1's red dot sight is larger than the G36C's in this game. Take your choice of topping (with or without the sodium benzoate) -- M4A1, G36C, and MP5, then follow the team to the farm.
Sneak into the farm and make your way to ambush the enemies. This mission pays if you stay silent until the very last minute; then you make sure there are no witnesses to any of your secret activities by shooting people repeatedly in the head.
Jump to the next farm and avoid the chopper by hitting the duck key (hold it to go prone on the console controllers). Once the chopper passes by you, head to the farmhouse and then dive into the basement once the door is bashed open. In the house, enemies will flashbang mid-way through.
Survive the house ambush and then enter the backyard area (no enemies yet). There's a secret here if you care for it, otherwise, you simply get yourself ready for attack dogs.

After escaping the house where the Russian chopper troops flashbang and ambush the team, you come across a peaceful back area with farm houses all around. Locate the house with the soda machine, enter it and claim the secret. If you meet attack dogs, you went too far ahead.
The attack dogs are dangerous only if you are not prepared to kill them. Basically, dogs will cause your character to go prone while being bitten. Unless you shoot the attacking dogs dead, you need to be ready to spam-press the melee button to break Rover's scrawny neck before it bites your neck and kills you.
Of course, the best way to get rid of dogs is with automatic gunfire. Spray the dogs if they get close, and keep behind cover so their handlers cannot shoot you dead while you are wrestling with their mangy mutts. Sweep the farm clean and head into the next field.
The next field is a stealth field, but you will eventually be caught anyway, since there is so little cover. Get as close to the greenhouses as possible by shadowing the team's movement and snipe the enemies if an alarm is raised (you may get lucky and sneak all the way to the greenhouses, so don't fire unless you are compromised!).
The two greenhouses are filled with enemies, as well as gunfire from the Russian chopper. You can kill the gunner (not the pilot) of the chopper by firing into the chopper's gunport. However, your more immediate threat are the 8 billion Russian terrorists on the ground who appear once the alarm has been raised.
Fighting through the greenhouses is a chore, made more difficult by the fact the fake grass will hide enemies but not their incoming bullets. Labor through the greenhouses and kill everyone to reach the barn. Although there is a secret before the barn, you can go and get it once the chopper and its soldiers are dealt with.

Upon leaving the second greenhouse, follow the building on the left to an area covered by a sheet metal roof. The laptop is in that area.
Head into the barn and use the Stingers to down the enemy chopper. Like the Javelin, you need to hold the weapon up with fine aim, achieve lock-on, then fire on the target. Two Stinger missiles will suffice.
When heading to the exfil point, enemy armor and soldiers appear. Wait until air support takes out the roadblock before advancing, otherwise, you will most likely get yourself killed.
