Camouflage - The clothing worn to match surroundings
Make sure you don't have anything that reflects on you as that can give your position away.  Couple of guys tried hiding out of bounds their scope glare gave their position away and they were dispatched.
American BDU | British DPM
These two designs are the two most commonly worn camouflage patterns in the UK.  There is an increase of people wearing German Flectarn.

The point of camouflage is to make yourself hard to spot by the enemy in your surroundings.  I myself prefer the DPM as it is darker like most of the wooded areas in England and the BDU's are a bit light in colour.  Both types of camo should be readily available at your local surplus store.

There are lots of different methods to attempt to cover up all the skin and hair with camo.  Most people wear the popular boonie hat to cover their hair and a green or black pair of gloves. Cam cream is a stick or tin of green and brown colours.  It is applied around the face and ears to cover the face.  It looks very impressive but by wearing face masks it should cover most your face anyway.
Above: A good example of gun camouflage
The gun camouflage in the above photo was simply constructed using a British Army scrim net covered by a small piece of camo net.  As you can see this is very effective even against a fellow team members camouflage jacket in the background of the photo.
A good example of comouflage, CHIFF is hiding in a bush at ambush wargames, the front of his gun has been covered with a camo net, as you can see this makes him almost invisible from even close ranges.
