Frustrated by the way BFBC2 players will happily sit and snipe while doing nothing to help the squad, or win the round, Tom Chick invents a new class, the sniper cop:

Did you know the tracer dart can stick to friendly targets? It sits there and glows. For instance, if you affix it to someone's head - say, someone with a sniper rifle crouching just behind a ridge or in some foliage - that person's head will be super easy to spot from a long way off by other players with sniper rifles. Furthermore, if you attach it to someone's face, it will shine a red glow into his line of site and maybe even obscure his vision. It's like a fantastic glowing clown nose
