in call of duty 4 online you can unlock certain gunskins & experience points by making a certain amount of headshots, i am a big fan of doing kage matches and i have noticed that some people ask for headshot trades.
the rules of it are very simple, one person stands still and reveals it''s location by shooting once or twice so he is seen on the map and when the other finds him that person can do a headshot on you, this is mostly done three times each untill the max limit has been reached.
if you need headshots but you can't get it fast enough then the kage matches will offer a good solution, simply send a message to the other player with the word hedshots? or headshot trade? in most of the cases he'll understand and reply to your message, of course it will go twice as fast if you use a headset instead but not everybody has these.
sometimes the other person doesn't want to so in that case you'll just have a good match.
Use mostly in grassy maps like Overgrown or Downpour. This also only works as you being SAS or Spetsnas.
These weapons/perks are required:
Primary Weapon: Any sniper rifle
Secondary Weapon: Any other weapon
Side-Arm: Any (silenced)
Perk 1: Bandolier
Perk 2: Over-Kill (For other weapon)
Perk 3: Any
The sniper rifle makes you have a ghillie suit (covered with leaves) on then go prone in a grassy area. Also, for your secondary weapon use a gun you want to kill and finish challenges with.
Okay, I hate those stupid enemy helicopters so heres my way of shooting it down!
-Get a rocket launcher(RPG)
-Follow the helicopter and wait till it stays still
-Shoot it with one rocket
-After shooting it, Quickly take out your primary weapon and fire a few shots and it should go down
I shot down 5 In one game with that trick <img src="http://i.neoseeker.com/d/icons/wink.gif" border=0 vspace=2 alt="" />

First, get in a building with two floors and that has about one or two entrances. Second, put (1) mine per entrance and on stairs. If the entrance is too wide then go ahead and put (2) mines, but make sure the mines are very far apart from eachother. Third, get in your sniping position and look around for 30secs. If in 30secs you don't find anything, switch position because it is likely that somebody is already trying to snipe you. Fourth, if anybody triggers your mines then make sure to go and finish them off or if they're already dead go ahead and replace the mine that was used. Repeat the Third step over and over until you get your desired kills, and happy sniping...
