Ambushing dummies

Only an idiot don't know how to ambush not to be mean but some people suck so hard a ambushes.One person can ambush the other team by his or her own self.here is so simple go under ground with claymores or C4.Make sure u place them out of sight or they will see it and go around.Once your done hide on the right side of the tunnel and wait if they see your IED blow it up,if not than put some rounds in the guy that always rushes ahead of his team.Then blow your IED's up on the guys hiding by the wall then if u have teammates have them go around and kill the one that chickened out.If you did this correct then you should win.(keep in mind you can only use this once or twice or they will get smart).Hope this works
