First off, let me say that campers blow hairy nads. In order to take them out you need a decent combination of a few things. The first big thing you need is numbers. It is NEARLY impossible to dislodge a well dug in force if you don't have equal or better numbers. With a bunch of guys on your team you can coordinate flanking and, as rockon 1 said, bunker moves. The second is skills. If you just started then you might want to work on snapshooting, this is where you pop out of your bunker and fire a few shots accuratly at them with the idea of being able to hit them first. A good backyard drilll my friend does is he sets up a paper plate on a post, walk kinda far away, then turn around real quick and try to shoot the plate as quick as possible. We used to laugh at him for doing this....key word USED.. he started snapshooting our asses off. Bunkering, if your not sure what that is, is when you run up on someone while they are taking cover in their bunker and shoot them several times at close range. Most of the time you go over the"top" of the bunker. Skills is something you get better with over time... Last there's position, this is something that you have to figure out on the field. Is their a way you can use their position to your advantage. Like, if they are down low in a gully, can you arc your balls to drop right on top of tem over their bunker. Sorry for the novel, hope it helps.....
