Chinese Embassy 2
When you come to the room with the sleeping guards you can avoid two of the guards by not continuing on to the next room, but instead, pick up the med kit, ammo, and frag grenade and go back the way you came in. Continue to the door at the end of the hall. On the left the code for the door is 1436.
The game now bypasses a part where two guards come and open the door. This way you never see those two guards - the part after it will have you stressed out enough as it is

MEET GRIMSDOTTR
In the very beginning of the game on the very first level, Lambert briefs you about Third Echelon, then sends you to an assault course. once he's done blabbing about red lights, he tells you to jump over a wall. Don't do it. go to you'r immediate right and double jump up on to the ledge. Once on the ledge look to your right once more. There is a door, and behind it is a closet or janitor's room with some shelves to your left. On those shelves is a pair of lock picks. Pick them up and go all the way to the end of the course, but don't finish it. Instead of going through that meatal hangar door, go to the right of it. There is another wooden door that is locked. Pick the lock and use the computer in that small room. It will give you a code for a servailance platform or something. That room is all the way at the beginning of the course to your left. where the room was with the lock picks, but on the other ledge. Go up that ledge and there you will find a door that is keypad locked. Use the code you got from the computer to get in. I could have told you the code, but what would the fun be in that? Behind that door is a small room with a doorway in front of you. Go through the doorway and Grim is to your left. You can talk to her, and she'll give you a litte more info on what you're doing here.
