Thousands of British troops are serving at a military base in Iraq's second biggest city, Basra. Newsround's Lizo went out there to see what life's like for them behind the headlines.
Iraq can be a really dangerous place and troops have to be really careful to make sure they stay as safe as possible.
People who don't want British troops in Iraq often attack the military camp with mortar bombs, which explode when they hit the ground.
There can be up to three or four attacks a day so the Army goes on regular patrols to try to stop them.
The Royal Navy guards the area by flying overhead in helicopters.
And the forces' four-legged friends are also trained to help by searching vehicles that enter the military camp.
All the vehicles have to be checked to make sure there are no bombs hidden on board.
The dogs have really sensitive noses so they can sniff out weapons and explosives.
Other dogs work with military patrols to keep out people who shouldn't be in the camp.
In this training exercise, the dog's chasing the 'intruder' away...
...but he didn't get very far!The dog knows how to grab the man's arm so he doesn't get badly hurt but also can't get away.
