Take an assault soldier with a M16 M203 or carbine 15 M203. Shoot them at the top of the broken buildings. You may might kill snipers easily if they are up there.
CTF weapon strategy
Have a Satchel Charge or Clamore and Grenade Launcher or any other gun mode. When your are near your flag, put down one or two satchels or claymores around it. Then, camp out somewhere that is elevated. When some one steals your flag, either detonate the satchel or blow up the satchel or claymore using your grenade launcher or gun.
Easy completion of Mogadishu Mile mission
Once the mission starts, run in front of the last AAV. Jump on the front of it to get an easy ride to the end of the mission. By doing this, you will be on top of it when they speed up and will not have to catch up. This results in you completing the mission faster and easier.
Large explosion
When you get C4s, lay them down and get some more. When you blow the C4 up, you will get a huge explosion. The best place to do this is in training; when you run out, go back and get more from the weapon crate.

Paperwork mode (CTF)
With the Red team, when you have the flag you are faced with two options. You can go the safe way and probably get killed, or jump off the ledge and take the risk that you might get killed. If you jump off the ledge use the following trick. When you want to jump off the ledge, make sure you have your grenade options out. Jump onto the ledge, but not off it. Turn around then jump backwards. While you do this, throw a grenade then lay down. Chances are, you will kill someone with your grenade or no one may be there. Do this each time and you will capture the flags all the time. With the Blue team, when you come into the flags you will see a table with a hole in it. You can either lay down some claymores in the side entrances then snipe, or grab the flag and run. If you run, try to get some people to follow you and capture the flag.

Team tag
While playing team tag online, if you have the flag some good places to take it to are as follows:
Gasoline Alley: In the garage; on the things that go along the entrance of the garage.
Black Hawk Down: On the broken buildings, top floor.
Last Defense: Keep running around in the trenches with M203s.
