Find the broken down train at the southern end of the map and take cover behind the barrels inside.

You can snipe people on the stairs or coming down the fastrope.
-Note: This requires that the free FanPack maps map be downloaded. It is possible to earn some fast A.C.E.S. points on the CQB Dark map--do this on solo so that no enemies are triggered before you are ready for them. Begin a Terrorist Hunt offline and make sure Lone Wolf is on. By doing this, your AI partners will not spoil anything for you. When the game loads, quickly change over to your pistol (Desert Eagle is recommended) and start walking to the corner of the wall on your left. As you near it, sprint around the corner and go up the ladder. The man at the end of the other room may attack you or call for back up, which is perfect. Do not stop to engage him or his friends. Quickly climb the ladder and take cover beside the concrete wall crouched down so that no one below can shoot you. Aim at the ladder and wait for them to come up one by one. When the count reaches 37 terrorists to go, it is time to trigger more. Go down the ladder and go to the room where you began. Go out into the courtyard ahead and move behind the pallets of sandbags. Move just so you can get a shot on the person in the building across from you on the right side of the doorway. Shoot him and run back for the ladder, then go back up and repeat the process. The count should now be 29 terrorists. Run across the map to the other ladder, entering at the closest door to you (behind the broken down van). Shoot at either of the men you encounter (in the window of the middle building or the corner of the far right building), then run for the ladder and go up. Repeat the process. Allow one minute to pass without terrorists to guarantee that it is safe to continue. Move to the wall behind you and do not leave the top of the ladder. Fire a couple rounds, then go back to the ladder. Repeat the killing and continue moving out into the outer perimeter of the building with the ladder. Once you narrow it down to about three to five terrorists that will not fall for your trap, hunt them down and kill them. You can clear the map on your own. You can do this under the Realistic setting at high enemy density. Every kill you make should be while they are on the ladder and you are behind them. You will get Kill At Close Range or more often than not, Kill Opponent From Behind A.C.E.S. points. Kill 40 terrorists like this and for 120 A.C.E.S. points per round.
-To earn a huge amount of A.C.E.S. for Marksman and CQB and a little bit of Assault, equip a sniper rifle with 6X12 scope Note: Any of them except for the first sniper rifle will work, preferably the automatic one. Play Story mode and select the chapter "Monorail". You will start with two doors in front of you--do not open them yet. Find the two supply boxes and open one to receive more ammunition for your sniper rifle. After that, open the doors and order your companions to guard the left entrance of the monorail. Note: If this isn't done, you will be killed from behind. Take cover, but not behind the plants. Also, make sure you don't cross the monorail hall or you will either be killed or will not get what you are looking for. The methods to getting A.C.E.S. after that are as follows:
CQB Once behind cover, pull out your sniper rifle but remain incover. You need to scope twice with your sniper. When the screen goes into focus, blind fire at the turrets and men, but beware as some rush. Your companions should take good care of them.
Marksman This is a bit tougher as it involves you not blind firing but coming out of cover to shoot. Scope into any of the men you see and always make head shots. Some might be too close for the "Long Range" A.C.E.S. and if you just shoot them on the chest, it will not get you the points. Some may rush but, once again, those two soldiers will help you.
Assault Advance through the monorail to your right while taking cover behind a blue box. A shielded opponent will emerge. Snipe him on his leg or arm and he should fall. Proceed forward until reaching the area where enemies charged down the stairs. There should be another shielded opponent on the opposite side. Either let your companions take care of him or you deal with him personally. This strategy should get you a massive amount of A.C.E.S. After every time you finally kill the shielded opponent on the opposite side of the bridge, just reload checkpoint and do it all over again.
After reaching the part of the level where you have to defuse the bomb on the door, have your team hold at the base of the stairs. Then, proceed up the stairs and stand a couple feet back from the double doors. Aim at the bottom of the doors and throw a grenade, then back away from the grenade fast so you do not die when the grenade goes off. A delayed rumble will occur and you will receive experience points. The amount of points is dependent on what difficulty you play at, and you will receive 2 A.C.E.S. Assault points for a kill with a grenade. You will fail the mission because it states that you "Disobeyed a Direct Order,"--but do not worry; you will not lose any experience and can just reload the checkpoint at the bottom of the stairs again. Repeat the process multiple times. This will help you effectively unlock guns and rank up. Note: This was done under the Realistic difficulty setting.
InChapter 1, The Pyrenees, there is a respawning enemy whom you canrepeatedly kill to gain CQB, Marskmanship, and Assault points. Justbefore Gabriel Nowak defuses the bomb, set a C4 charge on the pillarwhere the gun turret on the left will deploy. Order Nowak to "TeamDefuse Bomb", and detonate the C4 to kill the enemies past the shutter.There is one enemy who will continuously respawn on the balcony abovewhere Bishop and the team entered the bomb room. To gain CQB points,move close to him and kill him. To gain Marksmanship points, shoot himin the head. To gain Assault points, allow him to take the gun turretbefore killing him.
-On CQB, take a frag grenade and C4 as your gadgets. You should have an assault rifle with your other weapons. When you set it up, make sure your teammates are in the game at high enemy level and that it is on normal. Once you begin, tell your teammates to go to the box in front of you, then go to the corner to your right and take cover on that wall. Throw a grenade down at the other end of the building to get one or two kills. Wait for another terrorist to appear, then throw the other grenade to get three or four kills. Walk out the door to your left and take out your C4. Throw it inside the door to the brick building, then shoot the upper left green box in the brick building. Wait until some terrorists get close to the door. Detonate the C4 and keep doing this until the terrorists stop appearing. Go to the end of the brick and throw a grenade through the doorway. You should get a few more kills.
-Play single player Terrorist Hunt while making sure you have C4 on you. Select the Presidio map and set it to the Realistic difficulty and high density. Make it that so you are a lone wolf. Once done, launch the game. When you begin, go forward in the direction you are facing. Make sure to sprint to get there fast. After sprinting you should see a set of doors. Take cover next to the closest one and, after you are in cover, open the door. At the far end of the room there will be a man that will walk by. Take him out by precision aiming (firing from cover). On the left should be another set of doors. Throw a C4 in front of it, but not on it. Wait for one of the doors to open and detonate it, then throw in another C4 and detonate it. The most you should get is six kills, but it may be lower though. Repeat this to get a lot of Assault points.
Enter the Game Convention in Act 4 Scene 2-3 and go up to one of the arcade games. Two of them will read "Tom Clancy's Splinter Cell" on the top. If you look at their screen, the arcade machine will cycle through various gamer pics from the Splinter Cell series. Note: You can do this on the way to save the man from the bomb or on the way back.

-In the mission "Ambush", get to the end where you need to order one of your teammates to defuse the bomb. Order him to do that and stand beside him. He will complain about you standing next to you. Have your other person regroup and tell him to throw a grenade at the door in front of the bomb. You should get two kills. Next, look above you to see a person about to go on the turret. If you kill him, he keeps respawing. This is an easy way to boost your Assault points or any other desired A.C.E.S. points. Note: You will get more A.C.E.S. points under the Realistic difficulty setting.
-In Story mode under the Realistic difficulty setting, there is a glitch on the "Ambush" level. Proceed to the first bomb you encounter and tell your team to disarm it. While they are doing that, plant a C4 on the right window in front of the bomb, then turn left, look up top on the turret, and detonate the C4. You will see the enemies respawn. Continue killing them. They will keep respawning, allowing you to get an enormous amount of experience and A.C.E.S. You can do this as long as desired. Get an LMG for more ammunition. When you run out, restart the checkpoint.
